The Engineering and Physical Sciences Research Council (EPSRC) has committed a £4.9 million grant to fund a national research facility to support UK researchers in creating communications networks for the future.

A group of researchers from Universitat Politècnica de Catalunya in Barcelona, alongside Huawei, have re-tooled an artificial intelligence technique to improve efficiency in optical transport networks (OTNs).

Ciena has revealed its latest range of WaveLogic technology products, which includes a single-wavelength 800G solution.

Researchers at Royal Melbourne Institute of Technology (RMIT) in Australia have developed new fibre optic technology that can harness twisted light beams to more quickly carry and process data.

ADVA Optical Networking is developing a commercial device to support the Telecom Infra Project's (TIP) Disaggregated Cell Site Gateway (DCSG) group.

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.
