Orange trials Nokia’s PSE-Vs coherent optical engine for 400-Gbps transmission

Nov. 23, 2021
This trial, which the companies deemed a success, validated the ability of Orange’s fiber-optic network to support end-to-end 400-Gbps services using the PSE-Vs. Orange plans such an upgrade of its long-haul backbone networks, the companies add.

Nokia and Orange have conducted trials of the Nokia PSE-Vs, the communications technology supplier’s fifth-generation coherent optical engine (see "Nokia unveils WaveFabric Elements DSPs, optical engines starting at 400G"). This trial, which the companies deemed a success, validated the ability of Orange’s fiber-optic network to support end-to-end 400-Gbps services using the PSE-Vs. Orange plans such an upgrade of its long-haul backbone networks, the companies add.

The field trial, which followed a lab trial conducted 16 months prior (see "Orange tests Nokia PSE-V coherent engine performance over pan-European fiber backbone network"), leveraged a live network route of 914 km between Paris and Biarritz. The fiber link included 13 spans of Orange’s existing network through multiple cascaded ROADMs using 100-GHz WDM channels. The trial featured transmission rates as high as 600 Gbps per wavelength, thus confirming a roadmap to such performance in the future.

“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,” commented Jean-Luc Vuillemin, vice president of international networks and services at Orange. “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.”

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