Telia Carrier and Coriant Demonstrate Industry First Control of Fiber Capacity with Real-time Optical Awareness


owner and operator of the world’s number one ranked global
network backbone, and Coriant,
a global supplier of open, disruptive, and hyperscale networking
solutions for service providers and web-scale Internet operators, 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.”

Coriant will showcase the latest advances in Coriant Aware™ Technology
in a live demonstration at OFC 2018 in San Diego from March 13 – 15
(Booth #2239). To arrange a demonstration or schedule a meeting with our
