Telia Carrier, Coriant demo control of fibre capacity with real-time optical awareness

Tuesday 13 March 2018 | 19:10 CET | News
Telia Carrier and Coriant completed a live field trial of technology optimised for real-time optical performance awareness and dynamic provisioning of fibre optic capacity. The companies said the trial is an industry first. Conducted in December on a live fibre route in Telia Carrier’s backbone network between Hamburg and Prague, it demonstrated the ability to enhance end-user service reliability and improve operational efficiencies using innovations in online service planning, in-service optical margin measurement, and real-time health check analytics.

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 1,300-kilometer long-haul transmission route. Powered by Coriant Aware Technology and CloudWave Optics, the live field trial featured an industry-first demonstration of in-service optical margin measurement without the need for additional hardware equipment. Residual margin, which can be impacted by OSNR, linear impairments, and non-linear impairments, is the most useful measure of received signal quality and enables operators to determine how much room there is for a signal to degrade without impacting error-free operation. Assessing residual margin correctly will enable higher throughput, policy-based margin assignments and preventive maintenance, taking optical networking into a new era.

Coriant will showcase the latest advances in Coriant Aware Technology in a live demonstration at OFC 2018 in San Diego from 13 - 15 March.
