Nokia and Orange have completed 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.” 

Meanwhile, 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.”
