Having only one cabinet to install saves remarkably on installation time, reduces both weight and the needed space, and minimizes wind load.

There are also further benefits for design, logistics and assembly. One common challenge is minimizing cable scrap: Cabling costs are approximately 30% of the total site costs, and with an average cabling scrap rate of 17%, it equals to 5% of the total site cost. HELMACAB™ Hybrid Cable solution minimizes cable scrap costs due to simplified cabling systems from design to assembly. Installation time can also be minimized by customizing the number of cables and accessories.

A hybrid cable incorporates optical fibers and copper wires within the same jacket, and can supply power to devices while transmitting data. On campus networks, hybrid cables are typically used to connect access switches and WLAN APs, so that the access switches can supply PoE power to the APs while exchanging data with them. As future-proof WLAN technologies, such as Wi-Fi 6 and Wi-Fi 7, gain momentum, the conventional twisted pairs, however, cannot keep pace with the bandwidth needs of these technologies. Not only this, optical fibers cannot be used for PoE power supply. This is where the hybrid cable comes in.

The future-oriented Wi-Fi 7 standard further requires the cable to deliver a maximum of 40 Gbit/s bandwidth while supplying PoE power to APs over long distances. In most cases, APs are installed in complex environments and require PoE power supply over a distance of more than 100 m. In some special scenarios, the power supply distance will be much longer. For example, APs in some stadiums require 300 m or even longer power supply distances. The conventional twisted pairs, however, can only supply PoE power over a distance of up to 100 m.

As shown in the following figure, if twisted pairs are used, the network bandwidth can only be 10 Gbit/s at most without sacrificing the PoE power supply distance. If the network bandwidth reaches up to 25 Gbit/s, the power supply distance will be as short as only 30 m, which cannot cater to most PoE power supply scenarios. If optical fibers are used, the data transmission speed will not be limited, but we need to add a power supply system to supply power to the APs. However, it is hard to route power cables and manage this power supply system as APs are most often installed in complex environments. Facing this, we need to design a cable that can supply PoE power to APs without limiting the bandwidth evolution. This is where the hybrid cable comes in.

First, the hybrid cable maximizes the advantages of optical fibers. It transmits data signals via optical fibers that are used most often as an optimal means to transmit data over long distances and at high bandwidth. In contrast, twisted pairs transmit data signals via copper wires, and the transmission quality is easily affected by the wire resistance and capacitance, inevitably leading to attenuation and distortion of data signals.

Second, the hybrid cable minimizes the disadvantages of copper wires. Copper wires in a hybrid cable transmit only DC electrical signals. This means that the power supply distance can be quite long. According to Huawei’s tests, hybrid cables can supply 60 W PoE power even at a distance of 300 m. That said, copper wires still have resistance, and thermal effect still occurs during transmission, meaning there is still some energy attenuation. Therefore, the transmission distance over copper wires is limited even for DC signals. Essentially, the transmission distance of a hybrid cable depends on the transmission distance of DC signals over copper wires. But, as technologies and practices improve in the near future, we will see transmission distances reaching beyond 500 m, which will meet the requirements for long-distance PoE power supply in most scenarios.

- Visiomme on tuoda valokuidun ylivoimaiset ominaisuudet mahdollisimman lähelle käyttäjää. Tässä hankkeessa otimme konkreettisen loikan eteenpäin ja toteutimme käsityksemme mukaan Suomen ensimmäisen Fiber to the Office -toimiston, kertoo Lounean teknologiajohtaja Riku Päärni.

Lounea on toteuttanut Salossa sijaitsevaan pääkonttoriinsa uuden sukupolven langattoman sisäverkon, joka perustuu optiseen hybridikaapelointiin. Ratkaisu vie valokuidun suoraan Wi-Fi-tukiasemiin ja tuo samalla virransyötön samassa kaapelissa, mikä tekee verkosta entistä nopeamman, toimintavarmemman ja energiatehokkaamman.

Perinteisen kuparipohjaisen CAT-kaapeloinnin sijaan käytetty hybriditekniikka mahdollistaa pidemmät kaapelivedot, vähentää laitetilojen tarvetta ja yksinkertaistaa verkon arkkitehtuuria. Käyttäjille tämä näkyy tasaisempana kuuluvuutena, vähempinä häiriöinä ja pienempänä ylläpitotarpeena.

Lounean uusi ratkaisu on suunniteltu Wi-Fi 7 -sukupolvelle ja tulevaisuuden langattomille teknologioille. Optinen sisäverkko mahdollistaa jopa 10 Gbit/s -nopeudet ja luo perustan monikymmen­gigaisille yhteyksille sitä mukaa, kun päätelaitteet ja palvelut kehittyvät.

Lounea hyödyntää omaa pääkonttoriaan teknologian kehitysalustana, ja pilotin tulokset ovat olleet rohkaisevia. Yhtiön tavoitteena on paketoida ratkaisu osaksi yritysverkkopalvelujaan ja tarjota suomalaisille yrityksille entistä varmempi ja energiatehokkaampi verkkoratkaisu. Kansainvälistä tunnustusta innovatiivisuudesta saatiin jo syyskuussa, kun Lounea palkittiin Münchenissä Network Innovation Award – Innovation Pioneer -tunnustuksella pitkäjänteisestä valokuituinfran kehitystyöstään.
