Nokia and Orange announced the completion of a network trial using the Nokia PSE-Vs, its fifth generation super coherent optics.  With this field trial, Orange has successfully validated a planned upgrade of its long-haul backbone networks to support new high-bandwidth 400 Gb/sec services, and the ability to scale fiber capacity up to 600Gb/sec. This represents an increase in spectral efficiency by 50% compared to prior technologies on its long distance optical network.

The trial was performed in real-world conditions using Nokia PSE-Vs super coherent optics in production-ready optical transport hardware, just 16 months after the lab prototype trial done on Orange’s live network.  Orange and Nokia demonstrated error-free performance at a data rate of 600Gb/sec over a 914 km network between Paris and Biarritz, under challenging  live network conditions. The fiber network consisted of 13 spans of Orange’s existing network, through multiple cascaded reconfigurable optical add/drop multiplexers (ROADM), using 100GHz WDM spectrum channels.

Jean-Luc Vuillemin, Vice President of International Networks and Services at Orange, said: “With the booming market bandwidth requirement and need for scalability and flexibility, it is important that Orange continues to support an ever-greater network scale and new high-bandwidth services across our terrestrial and subsea global footprint.

Validating super coherent optics with Nokia represents an important enabler for future-proof networks which will bring spectral efficiency and operational deployment flexibility to our customer solutions. Furthermore this technology will allow for power savings by nearly 50%, which is key to our objective of developing greener networks for our customers. ”

James Watt, Head of Optical Networks Division, Nokia, said: “We are delighted to work with Orange in continued support of their network upgrade plans. With the introduction of the PSE-Vs super coherent capabilities across our entire 1830 portfolio, Nokia enables spectrally-efficient transport at 600Gb/sec over real-world long haul networks, and 400Gbps services over ultra long haul networks spanning multiple 1000’s of kilometers.”

The Nokia PSE-V
The Nokia PSE-V is the industry’s most advanced family of digital coherent optics (DCO), powering the next generation of Nokia high-performance, high-capacity transponders, packet-optical switches, disaggregated compact modular and subsea terminal platforms. The PSE-V Super Coherent DSP (PSE-Vs) implements the industry’s only 2nd generation probabilistic constellation shaping (PCS) with continuous baud rate adjustment, and supports higher wavelength capacities over longer distances – including support for 400G over any distance – over spectrally efficient 100GHz WDM channels while further reducing network costs and power consumption per bit.

Earlier this week, Nokia and Bell Canada announced the first successful test of 25G PON fiber broadband technology in North America at Bell’s Advanced Technical Lab in Montréal, Québec.

The trial validates that current GPON and XGS-PON broadband technology and future 25G PON can work seamlessly together on the same fiber hardware, which is being deployed throughout the network today. 25G PON delivers huge symmetrical bandwidth capacity that will support new use cases such as premium enterprise service and 5G transport.  Nokia’s 25G PON solution utilizes the world’s first implementation of 25G PON technology and includes Lightspan and ISAM access nodes, 25G/10G optical cards and fiber modems.

For the past decade, Bell has been rolling out fiber Internet service to homes and businesses across the country, a key component in the company’s focus on connecting Canadians in urban and rural areas alike with next-generation broadband networks. With this successful trial, Bell can be confident that its network will absorb the increased capacity of future technologies and connect Canadians for generations to come.

Stephen Howe, EVP & Chief Technology Officer, Bell, said:
“As part of Bell’s purpose to advance how Canadians connect with each other and the world, we embrace next-generation technologies such as 25G PON to ensure we remain at the forefront of broadband innovation. Our successful work with Nokia to deliver the first 25G PON trial in North America will help ensure we maximize the Bell fiber advantage for our customers in the years to come.”

Jeffrey Maddox, President of Nokia Canada, said: “Nokia innovations powered the fiber networks and the connectivity lifeline that carried Canadian homes and businesses through the pandemic. 25G PON innovations will drive the next generation of advances in our connected home experience.”

Bell and Nokia have closely collaborated over the years on many industry breakthroughs, such as the first Canadian trial of 5G mobile technology in 2016. Bell continues to work with Nokia to build and expand its 5G network across Canada.
