Nokia and Orange validate the performance of fifth generation super coherent optics on live network to enable 400Gbps services
18 November 2021
Espoo, Finland – Nokia and Orange announced today the completion of a network trial using the Nokia PSE-Vs, its fifth generation super coherent optics. This trial successfully validates Orange’s network capability to increase its optical capacity to support end-to-end 400Gbps services across its network.
With this field trial, Orange has successfully validated a planned upgrade of its long-haul backbone networks to support new high-bandwidth 400Gbps services, and the ability to scale fiber capacity up to 600Gbps. This represents an increase in spectral efficiency by 50% compared to prior technologies on its long distance 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 600Gbps over a 914km 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 multiplers (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 600Gbps over real-world long haul networks, and 400Gbps services over ultra long haul networks spanning multiple 1000’s of kilometers.”
Notes to editors:
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.
