Fiber optic testing updates

Few days ago I read The remarkable evolution of modern fiber-optic connector inspection probes article tells about the current state of fiber inspection. Especially with multifiber connectors such as MPO, MT, and MXC microscopic connector endface dirt and debris cause light reflections and attenuation – the enemies of optimal optical signal transmission. Thankfully there now

Low Energy: Mesh Bluetooth Technology

https://www.bluetooth.com/what-is-bluetooth-technology/how-it-works/le-mesh Bluetooth® Low Energy (LE) enables short-burst wireless connections and supports multiple network topologies, including a mesh topology for establishing many-to-many (m:m) device communications. New control and automation systems, from lighting to heating/cooling to security, are about to make homes and offices a lot smarter. Bluetooth mesh networking supports these smart buildings, enabling tens, hundreds

Probing Ethernet cable with an oscilloscope

This article talks about measuring 10 Mbit/s (10Base-T) and 100 Mbit/s (100Base-TX) twisted pair Ethernet signals. Those standards use two wire pairs for the communications and use differential signaling. Differential signaling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals,

A Photon Has Been Sent To Space Using Quantum Teleportation | IFLScience

http://www.iflscience.com/physics/a-photon-has-been-sent-to-space-using-quantum-teleportation/ Last month, Chinese researchers showed that quantum communication between Earth and space is possible, and now they have used the tech to send a photon to space using quantum teleportation. As this research shows, to create a truly global network for quantum communication, we will need quantum satellites.

The internet is actually controlled by 14 people who hold 7 secret keys | IFLScience

http://www.iflscience.com/technology/the-internet-is-actually-controlled-by-14-people-who-hold-7-secret-keys/ This sounds like something out of a Dan Brown book, but it isn’t: The whole internet is controlled by seven actual, physical keys. ICANN maps the numbers (easier for computers to use) with words (easier for humans to use). If someone were to gain control of ICANN’s database, that person would control the internet.  The physical

Researchers train drones to use Wi-Fi to look through walls | TechCrunch

A new system by University of California, Santa Barbara researchers Yasamin Mostofi and Chitra R. Karanam uses two drones, a massive Wi-Fi antenna, and a little interpolation to literally see through solid walls. One drone blasts Wi-Fi through the structure and another picks up the signal.

Who catches the IMSI catchers? Researchers demonstrate Stingray detection kit

https://techcrunch.com/2017/06/02/who-catches-the-imsi-catchers-researchers-demonstrate-stingray-detection-kit/?ncid=rss&utm_source=tcfbpage&utm_medium=feed&utm_campaign=Feed%3A+Techcrunch+%28TechCrunch%29&utm_content=FaceBook&sr_share=facebook What’s needed is an independent method of identifying IMSI catchers in the wild. That’s what University of Washington researchers Peter Ney and Ian Smith have attempted to create with SeaGlass. “Up until now the use of IMSI-catchers around the world has been shrouded in mystery, and this lack of concrete information is a barrier to

The Many Benefits of HTTP/2 – The Media Temple Blog

http://mediatemple.net/blog/tips/many-benefits-http2/?utm_source=facebook&utm_campaign=blog&utm_medium=paidsocial&utm_term=linkpreview&utm_content=http2 Now there is a budding new alternative to the endless caching and performance supplements. HTTP/2 — a new protocol update for HTTP by IETF (Internet Engineering Task Force).  HTTP/2 is the spiritual successor to HTTP/1 and provides much needed changes in security, speed, and usability. Let’s explore some of the key features and main benefits of implementing
