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.

Telia Carrier, Coriant successfully complete real-time optical awareness trials

Telia Carrier and Coriant have successfully completed a live field trial of technology optimised for real-time optical performance awareness and dynamic provisioning of fibre optic capacity.

The trial was conducted on a live fibre route in Telia Carrier’s backbone network between Hamburg and Prague. During the trial, 200G wavelengths were provisioned on-demand based on the accurate and real-time (DSP-independent) visibility of residual margin and OSNR on the 1,300km long haul transmission route.
