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.

A central European cable and satellite operator has successfully completed the testing of a hybrid last-mile broadband solution combining Iskratel’s GPON technology and Teleste’s DOCSIS-based mini-CMTS.

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.

Brazilian carrier Eletronet has chosen Ciena’s converged packet optical platform to launch new wavelength services across its national backbone network for wholesale, internet service providers (ISPs) and webscale companies.

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 has developed what it says is the world’s first single-chip L3 routing switch to directly integrate 100G network ports using single-mode fibre, and is now demonstrating its in-package optics platform to select customers and development partners.

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.

VIAVI Solutions has partnered with Microsemi to enable flexible optical networking technologies to meet the demands of 5G networks, providing service providers globally with solution platforms to build, test and quickly deploy 5G-ready optical networks including OTUCn, Flexible OTN (FlexO) and Flexible Ethernet (FlexE) technologies.

The latest Photonic Service Engine (PSE) family of super-coherent digital signal processors, from Nokia, PSE-3, implements its probabilistic constellation shaping technique (developed two years ago) to push fibre-optic performance close to the Shannon limit.

Optical start-up Ranovus has announced general availability of its 200G on-board optics and CFP2 direct detect transceivers. It plans to demonstrate both devices in partnership with ADVA Optical Networking at the upcoming OFC Exhibition in San Diego, California.
