OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software. Operation is possible at 300, 600, 1,200, 2,400, 4,800, 9,600, 14,400, 19,200, 28,800, 38,400, 57,600 or 115,200bit/s. “The actual fibre optic emitter and receiver pair can operate up to 5M baud – the shield ...
Perle Systems has introduced industrial grade real-time managed Ethernet switches with both fibre and copper ports, in a 45 x 93 x 109mm DIN rail mount package. “This represents a significant advancement in network infrastructure for industrial environments,” claimed the company. “The two 1000Base-X fiber connectors can extend Gigabit Ethernet operating distances over fibre up to 160km.” The fan-less units come ...
Wind turbine blades can be recycled, at least partially, accoriding to researchers at Aarhus University in Denmark. The chemical process disassembles epoxy composite, releasing intact glass fibres and extracting one of the chemical component of the resin. Both are as good as new materials, according to the university, which added that the process could also be used with some materials ...
Route planning has started on the pan-Arctic submarine cable that could link Europe, North America and Asia via the Northwest Passage – the latter opening as formerly permanent ice yields to climate change. The idea of the project, dubbed Far North Fiber, is to terminate in Japan, Norway and Ireland, and have branches to Alaska, Canada and Greenland (see map). ...
Beijing University of Technology has created red-green-blue lasing using three optical fibres coated with dye-doped polymer. Each whispering gallery fibre supports multiple lasing modes, with their colour defined by brushing on dye-doped polymer ink. Before weaving together, each fibre has a lower excitation threshold of 19.1μJ/cm2, narrowest spectral line width of 0.045nm and Q (quality factor) of 104, according to ...
Aiming at data centres, Ranovus and AMD are demonstrating 800Gbit/s optical comms at OFC 2022. The optical interface and its fibres, emerging from under the aluminium block The optical module co-packages Xilinx Versal ACAP (adaptive compute acceleration platform) and Ranovus’ Odin 800Gbit/s ‘CPO 2.0′ module. Odin is a protocol agnostic optical engine build around Ranovus’ 100Gbit/s/λ monolithic electro-photonic IC and laser ...
Fujikura Europe has launched its most compact active cladding alignment fusion splicer, engineered for network installers. Called 41S+, it borrows ‘active fusion control and ‘active blade management’ from the company’s flagship 90S+ model. Active fusion control activates when a cleave end face is bad quality, and automatically adjusts settings to improve fusion stability and decrease splice loss. “It also analyses fibre ...
Researchers at Washington University in St Louis have engineered bacteria to make ‘polymeric amyloid’, which, spun into fibres, achieved average ultimate tensile strength of 980MPa and an average toughness of 161MJ/m3. Lead by professor Fuzhong Zhang, the team was aiming to create a protein that forms ‘β-nanocrystals’, a significant component of natural spider silk. “Spiders have figured out how to spin ...
ProLabs of Cirencester has unveiled a plug-and-play optical fibre transceiver that can add DWDM to existing network infrastructure. Called Clarity Auto-Tuneable DWDM Transceiver, it plugged into the host device and passive mux, and is compatible with any OEM switch platform that supports SFP+ transceivers including switch platforms that do not natively support tuneable transceivers. The transceivers auto-discover and self-tune to individual ...
Direct GPS-over-fiber (GPSoF) from Huber Suhner allows a fiber optic connection to be made directly onto an antenna eliminating the need for a separate power line. This capability means power constraints in remote antenna applications landscape can be addressed at the remote end. Huber Suhner expects this capability to provide significant benefits to installations within the aerospace and defense markets. ...
