Trial Demonstrates Control of Fiber Capacity with Real-Time Optical Awareness
Telia Carrier and Coriant today announced the successful completion of a live field trial of cutting-edge technology optimized for real-time optical performance awareness and dynamic provisioning of fiber optic capacity. The industry-first trial, conducted last month on a live fiber route in Telia Carrier’s backbone network between Hamburg and Prague, 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.
“As the connectivity demands of our global customers become increasingly dynamic and unpredictable, we continue to look for new and innovative ways to enhance the service agility and flexibility of our infrastructure,” said Mattias Fridström, Chief Evangelist, Telia Carrier. “We were very pleased with the results of this trial, which proved out the operational value of optical performance awareness based on accurate residual margin measurement during real-time operations and state-of-life fiber conditions.”
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.
“Delivering the best user experience at the lowest network cost remains one of the most pressing challenges for our customers,” said Uwe Fischer, Executive Vice President, R&D and PLM, and CTO, Coriant. “This trial validates the progress we have made in delivering software-enabled tools that help network operators increase profitability through monetization of dynamic optical networks and the ability to adapt to changing customer needs in real-time.”
