Networking trends for 2018

Here are some of my collection of newest trends and predictions for year 2018. I have not invented those ideas what will happen next year completely myself. I have gone through many articles that have given predictions for year 2018. Then I have picked and mixed here the best part from those articles (sources listed on the end of posting) with some of my own additions to make this posting.This article contains very many quotations from those source articles.

Big Data, mobility and the Internet of Things (IoT) are generating an enormous amount of data, and data center operators must find ways to support higher and higher speeds. Recent data center trends predict bandwidth requirements will continue growing 25 percent to 35 percent per year. Many older data centers were designed to support 1-gigabit or 10-gigabit pathways between servers, routers and switches. Today’s Ethernet roadmap extends from 25- and 40-gigabit up through 100-gigabit, and 400-gigabit and even 1-terabit Ethernet loom within a few years. The biggest sales are forecasted for 25G and 100G ports for next few years. Ethernet switch market has now 100 Gbit/s products in the volumes at the moment, and both 200G and 400G Ethernet versions will be taken to use in 2018.

Broadcom dominates the Ethernet switch chip market today with a 73 to 94 percent share, depending on how market watchers slice the sector valued at nearly a billion dollars. Its closest rival, Cisco Systems, takes most of the rest with systems using its own ASICs. Juniper, Hewlett Packard Enterprise and Huawei also make Ethernet switch ASICs for their systems. With seven merchant chips in the pipeline and four in-house ASICs in the works, we will see a record number of unique platforms ship in 2018. Wheeler of the Linley Group expects the competition will drive Ethernet switch costs from about $60/port today to about $36/port by 2020.

Data center giants “are driving their own code and programmable capabilities as close to the server as possible.The dozen largest data center operators — including the likes of Facebook and Google — build their own switch systems or specify systems built by ODMs. They can drive sales of millions of chips a year but demand maximum bandwidth at minimum cost and power consumption. The Tomahawk-3 is geared for the next-generation of their top-of-rack and aggregation switches, delivering up to 128 100GE or 32 400GE ports, the first merchant chip to support 400GE rates.

China will start making more optical components: Several Western component and subsystems vendors have cited reduced demand from Chinese systems houses such as Huawei and ZTE for revenue declines in 2017. One reason for the slowdown is the fact that these systems houses have begun looking for more local optical technology sources. In addition to doing more development work in-house (particularly in the case of Huawei), the two Chinese systems vendors have begun to work more closely with Chinese companies such as Accelink, Hisense, and HiSilicon as well as Japanese vendors. This can mean that Western firms (particularly in the U.S.) may not see their Chinese orders return to previous levels.

Higher power power over Ethernet: 802.3bt – IEEE Draft Standard for Ethernet Amendment: Physical Layer and Management Parameters for DTE Power via MDI over 4-Pair amendment to IEEE Std 802.3-2015 increases the maximum PD power available by utilizing all four pairs in the specified structured wiring plant. This represents a substantial increase to the capabilities of Ethernet with standardized power – allow delivery of up to 90 watts of power via existing Ethernet cabling. The Ethernet Alliance has announced details of its next plugfest: Dedicated to pre-standard testing of Power over Ethernet (PoE) technologies against Draft 3.2 of the IEEE P802.3bt standard, the event will be held in February 2018. The specification’s ratification is expected in September of 2018.

802.11ax hasn’t been signed off yet, but promises to send WiFi towards 10 Gb/s thanks to its use of both multi-user multiple-input and multiple-output (MU-MIMO) and the new Orthogonal frequency-division multiple access (OFDMA). 802.11ax is  good at combining lots of different links so that users get more connections, more often, and end up with more bandwidth.  Marvell claims it’ll have the first chipsets for new 10G WiFi ready for products in H2 2018. Marvell said the chipsets will ship some time in early 2018 and will appear in products in the second half of the year. Widespread 802.11ax adoption in devices probably won’t happen until 2019.

5G something in it for everyone. 5G is big.  5G New Radio (NR) wireless technology will ultimately impact everyone in the electronics and telecommunications industries. Most estimates say 2020 is when we will ultimately see some real 5G deployments on a scale. In the meantime, companies are firming up their plans for whatever 5G products and services they will offer. Though test and measurement solutions will be key in the commercialization cycle. 5G is set to disrupt test processes. If 5G takes off, the technology will propel the development of new chips in both the infrastructure and the handset. Data centers require specialty semiconductors from power management to high-speed optical fiber front-ends. 5G systems will drive more complexity in RF front-ends .

Networks will become more and more virtual, especially on 5G. 5G networks will build on LTE network architecture with the introduction of cloud RANs (C-RANs) and virtualized RANs. Network function virtualization (NFV) and software-defined networking (SDN) tools and architectures could enable operators to reduce network costs and simplify deployment. For more details read System architecture milestone of 5G Phase 1 is achieved article.

Automotive Ethernet: Automotive Ethernet will replace the Media Oriented Systems Transport (MOST) bus found on many vehicles today and also compete with systems like Maxim’s Gigabit Multimedia Serial Link (GMSL). The standards include IEEE 802.3bw 100BASE-T1 and IEEE P802.3bp 1000BASE-T1 that adopt the 100-Mb/s and 1-Gb/s Ethernet protocols to run over over a single twisted pair up to 15 meters. Chips, PHYs and switches are now readily available for automotive Ethernet. Automotive switches will support time-sensitive networking (TSN) features like audio video bridging (AVB) ingress policy, rate limiting andalso features 802.1Qav/Qbv queue-shaping support. We will need a Security Blanket for Automotive Ethernet.

Car-to-car communication: The industry and government have defined several versions of vehicular communications. These are vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-everything (V2X). V2V is the direct communications between vehicles within range of one another. V2V link-up is automatic and cars exchange status information messages Basic Safety Message (BSM) 10 times per second (contains data such as GPS location, speed, direction, brake status, and related conditions). There are competing technologies to make this all work. IEEE802.11p ahead of LTE-V2V for safety critical applications. 5G will offer increased capacity and decreased latency for some critical applications such as vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communications for advanced driver assistance systems (ADAS) and self-driving vehicles. The big question is whether 5G will disrupt the landscape or fall short of its promises.

TSN (time sensitive networking) will be talked on many application. Success in the IIoT requires that information- and operational-technology networks work in tandem—time-sensitive networking can make it happen. A converged industrial network will address several challenges that currently exist in today’s disparate network architecture, and it is believed that needed convergence is provided by time-sensitive networking (TSN). TSN is a set of IEEE 802 sub-standards that, when implemented, enable deterministic communication over Ethernet networks while keeping the benefits of communication in best effort manner, on that same network. TSN introduces different traffic classes that share the same link. Proper implementation of TSN requires a solution that can provide a low latency and deterministic response at TSN end points and TSN bridges – it is usually implemented with combining a processor and a FPGA or using advanced Ethernet switch chip.

Gartner analyst says on-premises data centers will soon be ‘useless’: Govekar said that as soon as 2019, at least a third of the largest software vendors will have transitioned their products from cloud-first to cloud-only. For this reason Gartner analyst predicts doom for on-premises data centers. If this happens , there will be a lot of work for network operators and cloud service companies to be able to build the infrastructure that can handle all this without problems. I expect that not all on-premises data centers are doomed. There are applications where moving everything to central could does not make sense – for example many IoT applications are moving some of the processing from cloud to edge devices for various reasons (lower latency, reduce needed bandwidth, work also when communications does not work etc..). There is also place for some on-premises data centers on some application (may them be depending on need anything from embedded server to room full of equipment racks). When designing for the IoT, security needs to be addressed from the Cloud down to each and every edge device. Protecting data is both a hardware and a software requirement, as more data is being stored and analyzed in edge devices and gateways.

Network neutrality talks will continue in 2018. Federal Communications Commission (FCC) on December 14, 2017 overturned the Title II-based Open Internet Order the previous Democratic-controlled FCC regime put in place in 2015. So what happens next? In the immediate term, nothing. The Restoring Internet Freedom Order won’t go into effect until sometime in the first half of 2018.

IPv6 usage seems to be finally accelerating in 2018. IPv6 has been a “future” since 1998, and an important future since 2007. IPv6 deployments have been increasing and chances are you have already used IPv6 – but haven’t realized it yet. IPv6 deployment is increasing around the world, with over 9 million domain names and 23% of all networks advertising IPv6 connectivity. Network admins will have many concerns about migrating to IPv6 in 2018. China plans to put the Internet Protocol version 6 (IPv6)-based network into large-scale use, to boost the development of the Internet industry. China aims to have 200 million active users of IPv6 by the end of 2018. IPv6 use is increasing, but that does not mean that IPv4 is no way dying. It seems that both of those technologies will co-exist in Internet for a long time.

    Differences between industrial Ethernet switches and business IT switches

    Industrial network switches are designed for harsh conditions and environments and last for a long time while business information technology (IT) switches are designed for data center applications and have a shorter overall lifespan.

    Dirt. Dust. Vibration. Shocks. Electrical noise. Blistering heat. Freezing cold. The quick answer to the question of why industrial Ethernet switches differ from business information technology (IT) switches is the industrial Ethernet switch is built to withstand all these challenges. The business IT switch, cosseted by air conditioning in data centers or nestling in a quiet corner of an office where dust is a dirty word, doesn’t have to.

    Take dirt and dust. Business IT switches with fans for cooling will suck in air and, with it, dirt or dust particles. To compound the problem, fans have moving parts and lower mean time between failure (MTBF). Industrial network switches do not have fans. They rely on rugged design to resist heat better, and any buildup of dirt or dust.

    The components used to build authentic industrial network switches are designed and tested for operation in broad operating temperature ranges, for example from -40 to +75°C (-40 to +167°F). Commercial switches are built for operation within much narrower temperature ranges. Outside these limits, their integrated circuits may fail when temperatures are high, or their network connections may lose their contact because of the cold.

    Management and security considerations

    Often, industrial network switches have been installed, configured, and left to get on with it. The priorities were network speed and reliability. In older installations, network management functionality in the switch was not included, because it interfered with the high communications performance (high speed, low latency) needed. Security is also largely absent because in yesterday’s isolated industrial networks, nobody could get in from the outside to hack them. Business IT switches are typically equipped for both management and cybersecurity.

    With industrial networks are being connected to the Industrial Internet of Things (IIoT), they will need suitable management and security. Older industrial switches will gradually be replaced by new ones, although for all the reasons above, business IT switches will not be used. Management and security will need to be done differently, for example, via an industrial network with the intelligence and performance to help meet these requirements.

    Software-defined networking

    One robust, affordable solution that does have negative impacts on network performance is software-defined networking (SDN). By introducing SDN-compatible switches in the network, for instance, as part of the replacement program for older units, a software-defined network can make it easy to configure, control, and monitor Ethernet switches. This includes managing security policies in the switches on the types of traffic to let through or to block.

    Industrial network switches will continue to differentiate themselves from business IT switches, but at the same time be on par with them in terms of external networking, network management, and cybersecurity.

    Donald Trump Is the Toast of Sweden and Finland
    Nokia and Ericsson will be relieved at the blocking of Broadcom/Qualcomm.

    Donald Trump was the toast of Nordic boardrooms on Tuesday morning, after he blocked Broadcom Ltd.’s proposed acquisition of Qualcomm Inc.

    Telecoms equipment giants Nokia Oyj and Ericsson AB depend on Qualcomm for crucial chipsets used in their networks. The Finnish and Swedish companies each spend about 1 percent of their revenue on kit from the San Diego-based maker of semiconductors, according to Bloomberg supply chain estimates.

    That matters to Nokia and Ericsson because the more advanced Qualcomm’s technology, the better their own equipment will be.

    Crucially, the two companies aren’t just competing against each other. The big threat is Huawei Technologies Co Ltd. The Chinese telecoms giant designs its own chips, through its HiSilicon subsidiary, so far largely for cellphones themselves. It buys other gear from Broadcom. Should Qualcomm’s designs fall behind, that would threaten the Nordic manufacturers’ ability to keep pace with Huawei and, increasingly, Samsung. The South Korean company also makes its own chips and is expanding its equipment business.

    Molex Optical Solutions Group and Elenion team up to manufacture silicon photonics

    Molex Ventures has announced that its Optical Solutions Group (OSG) and Elenion Technologies, LLC (Elenion) will partner to develop, manufacture, and market silicon photonics technology. The strategic investment and collaboration between the Molex OSG and the semiconductor company will use CMOS and high-volume manufacturing processes to develop enhanced interconnect technologies that scale to 400 Gbps and up, Molex Ventures says.

    In March of last year, Elenion’s sister company Coriant offered a 200-Gbps short-reach CFP2-ACO pluggable optical transceiver for the Coriant Groove G30 Network Disaggregation Platform (NDP) that uses Elenion’s silicon photonics technology (see “Coriant offers 200-Gbps short-reach CFP2-ACO for Groove G30 platform”).

    Fujitsu enables 1.2-Tbps coherent transmission with DCO daughter card

    Fujitsu Optical Components Ltd. (FOC) said it has developed what it attests is the world’s first digital coherent optics (DCO) daughter card enabling up to 1.2-Tbps coherent transmission for various applications to support baud rates and modulation formats from 32-GBaud QPSK to 64-GBaud 64 QAM in fine resolution.

    The card can support applications including metro, 80 to 120km ZR transmission, long-haul, data center interconnect (DCI), and submarine to address capacity needs and system upgrades of data center operators and global network service providers. FOC says it plans to release the 1.2-Tbps daughter card for general availability later this year.

    The 1.2-Tbps DCO Daughter card uses in-house L-band LN modulator to support L-band transmission, in addition to the C-band, to enable large capacity coherent transmission in the C + L bands, says FOC.

    Broadband: Cable still adding, telcos still shedding

    Continuing a years-long trend, in 2017 cable added about 2.7 million broadband subscribers while telcos lost about 625,000. Cable companies accounted for 130% of the net broadband adds for the year.

    According to the Leichtman Research Group, the 14 largest cable and telephone providers in the United States – representing about 95% of the market – acquired about 2.1 million net additional high-speed Internet subscribers in 2017. Annual net broadband additions in 2017 were 78% of the 2.7 million net adds in 2016.

    The top broadband providers now account for nearly 95.1 million subscribers, with top cable companies having about 61.2 million broadband subscribers and top telephone companies having 33.9 million subscribers.

    Mixing 4G And 5G
    Why a hybrid solution is required, and what that means for future chips.

    5G networks will impact the number and types of ICs in end-user devices and the base stations used to transmit the signals (including the repeaters that rebroadcast those signals). And this is before we begin to consider the technology impact to the infrastructure required to support the data generated in a 5G ecosystem (servers, memory and so on).

    First, 5G is expected to transmit up to 10 times the data rate compared to today’s 4G technology. Additionally, 5G will have a greater number of multiple input (MI) streams/channels as well as multiple output (MO) streams compared to what is achievable today. However, because it is a higher frequency signal, it will only be able to transmit to a distance of about 150-200m and it will face absorption issues. 5G is short range and not suitable as a complete 4G replacement. The final solution will be some combination of 4G and 5G.

    EXFO unveils new test system for passive components

    EXFO Inc. (NASDAQ: EXFO) (TSX: EXF) has released what it asserts is the fastest component test system for insertion loss (IL) and return loss (RL) measurement for an array of passive components, such as photonics integrated circuits. The CTP10 component test platform combines technology obtained from EXFO’s acquisition of test and measurement instrument developer Yenista Optics in September of 2017 (see “EXFO eyes Yenista Optics acquisition”). The new CTP10 platform can be used by research scientists to characterize components, or in automated mode for high volume production, says EXFO.

    The growing demand for photonics integrated circuits (PICs) comprised of hundreds of passive components, and for lowering network equipment costs have contributed to passive component manufacturers’ need to decrease their testing time, while maintaining accuracy and reliability. According to EXFO, the CTP10 component test platform has a capability to measure IL and RL in a single sweep up to 1000 Nmps to address these challenges.

    “When EXFO acquired Yenista, the objective was to leverage their expertise to bring some of the most innovative testing solutions for the optical telecom industry,”

    Cumulus Networks announces availability of Cumulus Linux for early access on Voyager

    The availability of Cumulus Linux on Voyager follows the ADVA Optical Networking and fellow Telecom Infra Project (TIP) member InterNexa S.A. announcement in November 2017 that a successful trial of TIP’s Voyager open whitebox packet DWDM transponder platform was complete

    Integrating DWDM technology with switching and routing functionality, Voyager is the industry’s first open packet-optical transport system, Cumulus Networks attests. Cumulus Linux meets operator demand for scalable, affordable backhaul infrastructure to support growing internet usage worldwide and bandwidth-intensive applications, including scientific research, machine learning, video, and virtual reality.

    Cumulus says it offers interfaces for programmability and automation, along with delivering a L2/L3 stack, and an open Linux model that provides operators with deep, fabric-wide visibility. With the combination of IP and optical, Cumulus Linux’s routing protocol stack, VXLAN, and EVPN enable customers to build low-cost, high-performance long haul systems. The collaboration creates a market for Cumulus beyond the data center to data center interconnect

    Menara Networks announces availability of new OTN tunable SFP+ for commercial and industrial temperature applications

    Menara Networks said its OTN tunable SFP+ transceiver is generally available for commercial and industrial temperature applications. The “system-in-module” features integrated forward error correction (FEC) and improved monitoring capabilities.

    According to Menara, its OTN SFP+ is based on the company’s proprietary high speed integrated circuit, and delivers enhanced optical performance, FEC, and full G.709 OTN functionalities similar to functionalities in chassis-based DWDM transponders, in a pluggable small form factor.

    Compatible with all key routers and Ethernet/MPLS switches, the OTN tunable SFP+ processes 10G Ethernet, 10G FC, and 9.96 Gbps SONET/SDH transparently, and is the only module in the industry capable of 120 km reach without optical amplification or dispersion compensation at 11.1 Gbps, Menara asserts. With “near-end” and “far-end” in-service monitoring, Menara’s transceiver is well-suited for zero foot-print 10G NID applications, the company says. The Telcordia qualified module is tunable over the entire C-Band on the 50-GHz grid.

    So What Is 4.9G Anyway?

    Nokia is saying that it will start to offer “4.9G” technology by the end of the year, which could deliver download speeds of up to 3 Gbit/s over the air.

    So what is 4.9G anyway? Well, it’s basically another incremental upgrade to 4G LTE, this time super-charged with large antenna arrays. (See Eurobites: Nokia Promises ’4.9G’ in 2017.)

    Nokia’s Twist says pushing 4G to get “something close to 5G” speeds is important, because “the early implementations of 5G will be in islands.” At the moment, three carriers in the US — AT&T Inc. (NYSE: T), T-Mobile US Inc. and Verizon Communications Inc. (NYSE: VZ) — have access to 28GHz licenses that could be used for 5G. None have the licenses for nationwide coverage yet.

    LTE-A Pro and 4.9G networks are expected to be workhorse data networks long after 5G arrives

    Nokia reaches ultimate capacity of optical networks

    Nokia announced a new chipset it says will make it possible to boost the spectrum efficiency of optical networks to close to theoretical limits. The increases in capacity that will result in some instances could be as much as 65 percent.

    Nokia said its Photonic Service Engine 3 (PSE-3) coherent DSP is the first chipset to implement a technique called probabilistic constellation shaping (PCS), which improves the spectrum efficiency of nearly any optical network to close to the Shannon limit, while also reducing energy consumption. The figure for energy reductions is nearly as impressive as the capacity gain from the spectrum efficiency boost; it can be as high as 60 percent, Nokia claims.

    California Bill Seeks to Adopt Strict Net Neutrality Despite FCC Ruling

    As Americans wait to see whether net neutrality can gain enough support among lawmakers to invoke disapproval via the Congressional Review Act, individual states are not waiting — several are working on state laws to maintain net neutrality within their own borders.

    In December 2017, under the chairmanship of Ajit Pau, the FCC voted 3-2 to remove net neutrality protections by rolling back its earlier Obama-era classification of ISPs as telecommunications service providers (and therefor under FCC purview) to the common carriers as they had been previously classified. This has now happened. It simply means that existing FCC rules can no longer be applied to ISPs because they are not telecommunications services. This ruling won’t come into effect until April 23; that is, 60 days after publication of the ruling in the Federal Register.

    Nokia touts ultimate in spectral efficiency via PSE-3 chipset and probabilistic constellation shaping

    Nokia has unveiled what a company source described as possibly “the final piece of the puzzle when we talk about coherent transmission.” The company says the Photonic Service Engine 3 (PSE-3) coherent chipset provides the ultimate in spectral efficiency thanks to its use of a digital signal processing (DSP) technology called probabilistic constellation shaping. The technique, paired in the PSE-3 with 64-QAM modulation, can increase fiber capacity by as much as 65% over current deployments, Nokia asserts.

    IEEE Publishes Standard Specifying 200 Gb/s and 400 Gb/s Ethernet

    IEEE, the world’s largest technical professional organization dedicated to advancing technology for humanity, and the IEEE Standards Association (IEEE-SA), today announced the availability of IEEE 802.3bs-2017-Standard Amendment for Media Access Control (MAC) Parameters, Physical Layers and Management Parameters for 200 Gb/s and 400 Gb/s Operation. The new standard amendment addresses the growing diverse bandwidth requirements and cost considerations from network providers needed to meet the burgeoning high-bandwidth requirements driving a range of different application areas, such as cloud-scale data centers, internet exchanges, co-location services, and broadband wireless infrastructure.

    “When you consider the notable move to 25-50 Gb/s Ethernet for servers and 100 Gb/s Ethernet for networks, it has become clear through proactive engagement with industry that 200 Gb/s and 400 Gb/s Ethernet is needed to meet growing capacity demand for high-bandwidth services today and for the future,” said John D’Ambrosia, chair, IEEE 802.3bs and senior principal engineer, Futurewei, a subsidiary of Huawei. “The publication of IEEE 802.3bs represents a nearly 5-year endeavour to ensure Ethernet’s continuing support of the accelerating curve for higher bandwidth that can support ongoing robust industry growth and expansion.”

    Renesas RV2X6376A Laser Diodes for 5G LTE Base Stations and Server Racks

    Renesas Electronics Corporation announced the RV2X6376A Series of directly modulated laser (DML) diodes. The DML diodes deliver 25 Gbps x four wavelengths as the light source in 100 Gbps optical transceivers that enable high-speed communications inside 4.9G and 5G LTE base stations, and between data center routers and servers. The RV2X6376A Series are the industry’s first DML diodes that support full 25 Gbps speed (per individual laser) and industrial temperature (-40°C to 95°C) without cooling.

    The RV2X6376A Series are designed into compact 100 Gbps QSFP28 optical transceiver modules that use conventional NRZ modulation. They are compatible with the Coarse Wavelength Division Multiplexing (CWDM4) standard that specifies four lanes of 25 Gbps optically multiplexed onto and demultiplexed from duplex single mode fiber. The RV2X6376A Series extend the laser diodes family, joining the proven, commercial temperature grade (-5°C to 75°C) NX6375AA Series used in data centers.

    Mobile communications and the Internet of Things (IoT) are driving high-speed optical communication systems, which are experiencing rapid growth due to an explosion of data usage. The Cisco® Visual Networking Index (VNI) forecasts global mobile data traffic to grow 44 percent annually from 11,000 Petabytes/month in 2017 to 48,000 Petabytes/month in 2021. To service this hyper-growth, base station manufacturers are transitioning to interim 4.9G and higher throughput, low-latency 5G technology.

    Ciena offers 8180 Coherent Networking Platform, 6500 Reconfigurable Line System to aid fiber network densification efforts

    Ciena (NYSE: CIEN) used OFC 2018 in San Diego, CA, last week to unveil the 8180 Coherent Networking Platform and 6500 Reconfigurable Line System (RLS). The two platforms are designed to provide the aggregation, scale, and programmability that network operators will need as they embark on fiber network densification strategies.

    Operators are looking for scale, operational simplicity and rapid deployment capabilities, a means to grow their competitive edge, and a way to ensure the best customer experience possible as they extend their fiber footprints, to support such applications as data center interconnect
    (DCI), 4G/5G backahaul and front haul, and cable systems operator’s “Fiber Deep” initiatives, according to Helen Xenos, senior director, portfolio marketing at Ciena. An optimal approach would leverage highly scalable, small-footprint platforms that provide programmability and built-in Layer 2 capabilities, she said.

    The two new platforms aim to meet these requirements. The 8180 Coherent Networking Platform scales to 6.4 Tbps of switching capacity within a 2RU chassis. It also will support tunable 100- to 400-Gbps coherent transmission based on Ciena’s WaveLogic Ai engine as well as 10, 40, 100, and eventually 400 Gigabit Ethernet client side ports. It is fully compatible with Ciena’s full software-defined networking (SDN) and network automation suite, Xenos added.

    Full duplex coming soon to a fiber near you

    CableLabs is working on a new fiber technology, Full Duplex Coherent Optics, an approach that is being incorporated into CableLabs’ point-to-point coherent optics specification, which is slated to be issued later this year. Changing network topology configurations will not be required.

    Full Duplex Coherent Optics enables a coherent signal to be transmitted over the same fiber using the same wavelength, simultaneously in the downstream and upstream directions. This differs from traditional coherent optic links, which use the same wavelength but a separate fiber for the downstream and the upstream. Non-coherent systems, on the other hand, use a single fiber, but two wavelengths.

    “The coherent technical approach CableLabs has proposed uses one wavelength and one fiber, meaning it uses only one-half of fiber wavelength resources [compared to] traditional technologies,” said Steve Jia, CableLabs distinguished technologist, wired technologies.

    Coherent optics could potentially increase the fiber capacity of any existing access network fiber by 200 times. The way this would play out in a traditional system is that if an operator has 10 wavelengths in the downstream direction and 10 in the upstream direction, carrying coherent signals, the total system requires 20 wavelengths. With the full duplex coherent optics mechanism, the same system can carry these signals using only 10 wavelengths.

    Cable operators will be able to meet the increasing bandwidth demand without the need to lay more fiber or redesign chips for signal processing, CableLabs says.

    Huawei introduces 400G optical network technology for commercial use
    March 20, 2018

    Huawei used the Optical Networking and Communication Conference & Exhibition (OFC) last week to introduce 400G optical network technology for commercial use. The technology is designed to provide rapid 400G optical network deployment for all service scenarios on carriers’ networks.

    Huawei’s 400G offering leverages its latest oDSP chips, which the company claims enables its platforms to surpass industry standards in transmission performance. It supports adjustable bandwidths at a tunable single-wavelength rate ranging from 100 Gbps to 400 Gbps. By delivering a variety of flexible configurations, this technology offers carriers accelerated 400G network deployment on live networks, says Huawei.

    Huawei says its 400G optical network technology targets actual commercial scenarios to optimize high-speed optical transmission signals, including slicing, shaping, and compression, and balancing between theoretical limits and commercial use. Huawei asserts that it meets the requirements of a variety of service scenarios by giving the best possible transmission performance within transmission limits, including the following:

    No future-oriented IT megatrends without real time capable fiber optics

    The digital transformation casts its shadows. The world of applications is thrown upside down. The purpose and size of the project take a back seat. Users with their expectations of a modern, digitized world are in the focus of attention. Edge Computing and the new 5G mobile network are on everyone’s lips. They are the prerequisite for real-time applications and low latency. But are these pure hype topics or concrete solutions that make future-oriented applications possible in the first place?

    Experts agree: without a modern, real-time-capable infrastructure, neither the Internet of Things (IoT), nor autonomous driving or Smart Cities can be realized. The fact is that data volumes around the globe are exploding. Real-time applications need to be processed within seconds and in the area where they are created and used.

    In the case of autonomous driving cars, for example, all data processing is carried out directly in the vehicle. Reactions must occur within milliseconds, for example to prevent accidents. The necessary real-time data processing is only possible with 5G mobile communications and Edge Computing. The construction of structures is no magic trick, because network nodes for edge computing can be integrated in the next street light, an advertising pillar or near a mobile radio cell, even in the middle of such a cell. Data processing at its best.

    A dream of the future? Not at all! At the 2018 Winter Olympics in South Korea, for example, visitors and athletes at the venues have already been able to test a 5G installation and immerse themselves in the world of new applications. At the Mobile World Congress 2018 in Barcelona, 5G was also one of the central themes. Commercial projects based on 5G are already planned for 2018 in the EU. The Federal Ministry of Transport and Digital Technologies estimates that by 2020, rapid mobile communications technology will then be available everywhere.

    The speed of Ethernet quadruples

    Ethernet Alliance has announced a new roadmap technology for future development. Even after five years, the data rate of local area network technology can reach up to 1.6 terabytes per second.

    In the Alliance Roadmap, the fastest Ethernet speed for this moment is 400G, or 400 gigabytes per second. Fourfold speed requires improvements both in the number of lines, signal sampling, and modulation.

    For example, the 400G speed can be implemented in different ways. On four lines it will succeed if one line speed is 400 gigabytes per second. If there are 16 lines, there is enough 25 gigabit speed per line.

    To gain 1.6 terabytes it is necessary that the modulation is updated either to the PAM4 signaling input, which transfers two bits of data in each frame. PAM8 signaling increases this to three bits per frame and a new coherent signaling for 4 bits in the frame.

    Why Did Swarm Launch Its Rogue Satellites?

    Nearly two weeks after IEEE Spectrum broke the news that Swarm Technologies had carried out the first ever unauthorized satellite launch, mystery surrounds the company’s reasons for doing so. And uncertainty clouds the air around it because it’s not clear what the consequences for the stealthy start-up might be.

    For the past two years, the company has been working on four small SpaceBee satellites, prototypes for an innovative constellation it believes will enable Internet of Things data communications for as little as one-hundredth the cost of existing services.

    In November, Swarm’s founder, Sara Spangelo, delivered the four satellites to Spaceflight, a company in Seattle that consolidates multiple small satellites (often called Cubesats) for launch alongside larger payloads.

    Nokia reaches ultimate capacity of optical network

    Nokia announced a new chipset it says will make it possible to boost the spectrum efficiency of optical networks to close to theoretical limits. The increases in capacity that will result in some instances could be as much as 65 percent.

    Nokia said its Photonic Service Engine 3 (PSE-3) coherent DSP is the first chipset to implement a technique called probabilistic constellation shaping (PCS), which improves the spectrum efficiency of nearly any optical network to close to the Shannon limit, while also reducing energy consumption.

    TSN solves measurement and control challenges

    Time-sensitive networking (TSN) is an evolution of standard Ethernet and adds the bounded latency and guaranteed bandwidth provided by hard real-time Ethernet, which is crucial as more devices are connected to the Industrial Internet of Things (IIoT).

    Of the 50 billion devices it is said will be connected by the year 2020, experts estimate that the industrial sector will account for nearly half. This means that engineers and scientists have a big voice when it comes to implementing the Industrial Internet of Things (IIoT) across factories, test laboratories, power grids, refineries, and infrastructure.

    The global processing industry is an early adopter of IIoT, and it’s easy to see why. Unscheduled asset downtime in the industry costs $20 billion annually, 80% of which is preventable, according to ARC Advisory Group. However, it’s not just the global processing industry that can benefit from IIoT. Among business leaders, 95% expect their companies to use the IIoT within the next 36 months.

    Engineers can expect to gain three key benefits:

    Increased uptime with predictive maintenance
    Boosted performance with control at the edge
    Improved product design and manufacturing through connected, real-world data.

    A few challenges arise when attempting to develop such a system:

    Synchronizing the potentially thousands of channels and numerous measurement systems
    Synchronizing the control systems such that all actuation happens at the correct time
    Synchronizing the measurements and control systems.

    These challenges are further exaggerated as systems grow, and more measurement and control capabilities are added to an application. Synchronizing measurement systems with other measurement systems, and control systems with other control systems, is not a new challenge. Typically, this can be achieved with signal-based methods, in which physical cabling is used to route a common time base or signal to distributed nodes. Unfortunately, this has limitations on distance and scalability, as well as a risk of noise.

    Another possibility

    Figure 2: Time-sensitive networking is the evolution of standard Ethernet to include time-based synchronization, traffic scheduling, and system configuration. Courtesy: National InstrumentsAnother option is to leverage a protocol built on top of a common standard like Ethernet. Ethernet offers openness and interoperability but has no bounds for latency or guarantees for bandwidth. To solve this challenge, custom versions of Ethernet, often referred to as Hard Real-Time Ethernet, have been developed. EtherCAT, Profinet, and EtherNet/IP are prime examples. These custom variants of Ethernet provide hard real-time performance and best-in-class latency and control. However, each variant includes both hardware and software modifications to network infrastructure, which increases costs and means different devices from different vendors cannot function on the same network.

    A new technology to solve this synchronization challenge is coming to market now, called time-sensitive networking (TSN). TSN is an evolution of standard Ethernet that provides openness and interoperability but adds the bounded latency and guaranteed bandwidth provided by hard real-time Ethernet. Specifically, TSN delivers three key components: time-based synchronization, traffic scheduling, and system configuration. The synchronization capabilities are based on the IEEE 1588 precision time protocol profile, providing a sub-microsecond level of network synchronization. In addition, traffic scheduling and system configuration power deterministic data communication, so users can schedule and prioritize time-critical data (such as control signals) across the network.

    An important aspect of TSN is the convergence of time-critical traffic and other Ethernet traffic. Because TSN is a feature of the Ethernet standard, the new capabilities of time synchronization and deterministic communication run over the same network as other network communication. This means a single port on the measurement or control system can perform deterministic communication while also updating remote user interface terminals and supporting file transfer.

    TSN is a key enhancement for many industrial applications, such as process and machine control, in which low communication latency and minimal jitter are critical to meeting closed-loop control requirements. Time-based synchronization over Ethernet also minimizes cabling traditionally found in monitoring applications and physical system testing (like our structural example) leading to a simpler, cost-effective solution without sacrificing reliability.

    11 Myths About Wireless

    1. Wireless was invented by Marconi.

    No, it was not. I would give my vote to Heinrich Hertz

    2. The Federal Communications Commission is the primary communications regulator.

    But they aren’t the only U.S. regulatory agency.

    3. Radio waves work like magnetic induction.

    Not so. A radio wave is really a combination of an electric field at a right angle to a magnetic field.

    4. The propagation of a radio wave is basically the same for all wireless applications.

    No way. Radio signals act differently depending on their frequency.

    5. We have totally run out of frequency spectrum.

    Not completely, but we’re working toward that it seems. Most of the so-called “good” spectrum (~500 MHz to 6 GHz) is pretty much consumed, but plenty of spectrum exists at the higher frequencies beyond about 30 GHz.

    6. Radio broadcasting is dead.

    You may have gotten the impression that AM, FM, and TV broadcasting were on their way out thanks to all the internet streaming of music and video. But it’s not. While the number of AM stations has declined a bit, FM is growing. Satellite radio is also healthy. Furthermore, almost 20% of the U.S. population gets its TV by over-the-air (OTA) broadcasts. This includes satellite TV broadcasting. On top of that, short wave broadcasting is still around

    7. The most widely used wireless standard is Wi-Fi.

    Wi-Fi is certainly a heavily used wireless standard. But in terms of sheer volume of radios in use, Bluetooth is probably the more widespread.

    8. Cell phones give you a brain tumor.

    That myth has been around ever since the first cell phones emerged in the late 1980s. It’s been studied multiple times, and the outcome is that cell phones don’t cause brain tumors.

    9. Wireless data transfer is always faster than wired data transfer.

    Not true. Wired data communications say by Ethernet or fiber optics, is very solid and usually faster than wireless. Ethernet can do 100 Gb/s and optical is now doing up to 400 Gb/s using PAM4. With a solid link, data can be faster because it doesn’t have to deal with all of the free space link and path problems of wireless.

    10. Rain and snow make satellite TV, phones, and data services unreliable.

    You have probably heard of this one but it not true. Actually, at some frequencies in older systems, rain does attenuate the signal. But today, most components, equipment, and systems compensate for it with good link margins.

    11. Millimeter waves will never be practical.

    today mmWaves are widely used thanks to the availability of semiconductor devices to generate and process these signals. Millimeter waves cover the 30- to 300-GHz range.

    OTDR – Optical Time Domain Reflectometer

    An Optical Time Domain Reflectometer (OTDR) is an important instrument used by organizations to certify the performance of new fiber optics links and detect problems with existing fiber links.

    Tier 2 (Extended) Fiber Optic Certification
    Better Network Visibility with Tier 2 Certification of Fiber Installations

    Pass/Fail Inspection and Beyond

    While Tier 1 fiber optic tests can identify problems in terms of pass or fail, they cannot determine the root cause or location of the problem. Tier 2 fiber optic testing is used to pinpoint root-cause locations and the amount of loss and optical return loss (ORL) from each problem contributor and is performed selectively in addition to Tier 1 testing under specific conditions and situations. Tier 2 fiber testing provides a deeper level of link visibility unlike any other fiber infrastructure tests. The optical time-domain reflectometer (OTDR) is used to perform Tier 2 fiber optic testing.

    Infrastructure Verification as a Service

    A standardized approach to infrastructure documentation and maintenance

    It is a widely accepted truth that all information and communications technology (ICT) infrastructures require some level of documentation in order to be properly maintained. From the specific contents of their spaces and pathways to cable endpoint documentation, most organizations want accurate documentation of their infrastructure, while few actually have it. The disparity between the ICT documentation “haves” and “have-nots” is attributable to the lack of a standardized approach to conducting a comprehensive, and verifiable, survey-documentation-maintenance effort against an existing infrastructure.

    In the case of internal survey-­documentation-maintenance attempts, organizations often are met with a series of obstacles that prove difficult, if not impossible, to overcome independently; resource limitations coupled with issues such as key person risks, lack of standardized training, conflicting requirements, and access coordination, all amount to fracture points inherent in most internal programs.

    As the growth of the infrastructure outstrips the accuracy of the initially collected data, additional surveys are needed to produce a “here-and-now” inventory audit, with little (or false) expectation of any effort to maintain the resulting documentation beyond the immediate need of the current project.

    This mentality has helped to cause industry-wide resignation to infrastructure disorganization, resulting in its acceptance as the de facto baseline for new projects.

    “The key, I believe, is to have someone ‘own’ the responsibility of keeping documentation updated,” says Cindy Montstream, RCDD, director of technology support and training with Legrand North America.

    Clearfield says pre-connectorized aerial terminal sets benchmark for faster FTTx deployments

    Clearfield, Inc. (NASDAQ: CLFD), a specialist in fiber management for communication service providers, has introduced its YOURx-Aerial Terminal, an enclosure for optical service aerial applications aimed at reducing service provider operational costs.

    According to Clearfied, “The YOURx-Aerial Terminal is a free-breathing, aerial interconnection point supporting up to 144 fiber feeds with a distribution capability of up to 24 individual service drops per site. It can mid-span a larger count fiber cable, allowing the service provider to deploy multiple terminal access points along the same cable run, thus maximizing their fiber investment. Another installation headache for both contractors and service providers is excess fiber slack storage, and this has also been addressed by accommodating ample internal slack storage capability of ribbon or loose tube fibers.”
