NeoPhotonics has completed experimental verification of the transmission of 400Gb/s data over data centre interconnect (DCI) ZR distances in a 75GHz spaced dense wavelength division multiplexing (DWDM) channel.
Deutsche Telekom Global Carrier, the international wholesale unit of Deutsche Telekom, has turned up its European 800G network, connecting its data centres in Vienna.
Inphi is now sampling the new Canopus coherent digital signal processor (DSP), which it calls the industry’s first merchant 7nm coherent DSP.
Industry market research firm, Cignal AI has released its 1Q19 Optical Applications Report.
Network core flexibility will become just as important as capacity for future networks, and coherent solutions could be key to accommodating changing traffic flows, argues Eugene Park
Nokia, in partnership with Netia, has conducted a field trial of Photonic Service Engine 3 (PSE-3) super coherent technology over a live production network.
Cignal AI has released its Optical Applications Report for the third quarter of 2018, which details a healthy growth of coherent 200G shipments during the period, even slowing the adoption of lower 100G speeds.
CableLabs has published two new specifications to ‘dramatically increase’ capacity of the fibre access network with point-to-point coherent optics technology, allowing for 100Gb/s per wavelength.
Using amplitude, phase, and polarisation to enable much higher fibre capacities, coherent optics can help to improve streaming, video conferencing, file uploads and downloads and future usage needs for technologies such as virtual and augmented reality, and by gaining more capacity from existing fibres, the need to lay more can be eliminated.
