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.

Ciena’s GeoMesh chosen to enhance submarine networks in Caucasus and Latin America

Ciena’s GeoMesh Extreme open network architecture with high-density 100G transponders has been selected to enhance two submarine networks in the Caucasus and Latin America regions.

As sole owner of the Black Sea submarine cable, Caucasus Online provides critical services in regional communications, acting as a major gateway for internet traffic from Europe to South Caucasus and the Caspian region.

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.

Rockley Photonics raises $40 million funding for platform expansion

Rockley Photonics has raised $40 million in its most recent round of funding, taking its total raised since its launch to $100 million. The company says that this will rapidly expand the design and production of its platform for high performance optical networking solutions, imaging and sensor photonics, and custom photonics for consumer applications.
