Consequently, while 400 gigabit ethernet (GbE) is currently enjoying widespread deployment, 800 GbE is poised to rapidly follow to address these bandwidth demands. https://phys.org/news/2021-06-lasers-capable-transmitting-gigabits-gigabit.html Optics & Photonics Fri, 04 Jun 2021 13:49:01 EDT news542033332 Our world needs reliable telecommunications more than ever before. However, classic devices have limitations in terms of size and cost and, especially, power consumption—which is directly related to greenhouse emissions. Graphene could change this and transform the future of broadband. Now, Graphene Flagship researchers have devised a wafer-scale fabrication technology that, thanks to predetermined graphene single-crystal templates, allows for integration into silicon wafers, enabling automation and paving the way to large scale production. https://phys.org/news/2021-02-wafer-scale-production-graphene-based-photonic-devices.html Nanomaterials Thu, 11 Feb 2021 10:56:22 EST news532263379 The amount of data traffic on the internet and between servers in datacenters has exploded in the past few decades and shows no signs of slowing down. For example, Ethernet technology, used in small to medium-sized networks, has evolved from an original speed of 2.94 megabits per second to 100 gigabits per second, an increase of more than 3,000-fold. An IEEE 400 Gb/s Ethernet Task Force has been formed to take the standard up to 400 gigabits per second in the next year or so, and even this may not be enough for some especially data-heavy companies. https://phys.org/news/2016-02-record-breaking-transmission-capacity-paves-faster.html Telecom Thu, 18 Feb 2016 11:13:54 EST news375016421 (Phys.org)—Carnegie Mellon University's latest robot is called Snake Monster, however, with six legs, it looks more like an insect than a snake. But it really doesn't matter what you call it, says its inventor, Howie Choset—the whole point of the project is to make modular robots that can easily be reconfigured to meet a user's needs. https://phys.org/news/2015-01-six-legged-snake-monster-reconfigurable-modular.html Robotics Wed, 14 Jan 2015 07:50:03 EST news340443553 In the depths of night on August 5th 1914 the British Cable Ship Alert took the first significant action of World War I, severing the five German submarine cables that ran through the English Channel.
