800G network launched in Vienna

Deutsche Telekom Global Carrier, the international wholesale unit of Deutsche Telekom, has turned up its European 800G network, connecting its data centres in Vienna.

Flexible friend

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

CableLabs specifications bring higher speeds to access networks

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.
