Recently, Nokia and Orange announced that they have successfully set a single-carrier 800Gbps transmission record on the 6600-kilometer Orange transatlantic route Dunant using the super-coherent optical transmission module based on PSE-6s on the Nokia 1830 PSI-M modular optical transmission platform. The trial was conducted under challenging existing network conditions, validating Orange's ability to increase the capacity of existing optical networks to support end-to-end 400GE and next-generation 800GE services.
The Orange transatlantic submarine cable route Dunant won the 2021 Global Operator of the Year Submarine Project Award. It is a unique "hybrid" land and submarine connection solution for commercial wholesale customers. Its traffic can reach four different POP points in the Paris area, providing more connection options for commercial wholesale customers.
In the trial, Orange and Nokia demonstrated error-free transmission performance of single-carrier 800Gbps on a link up to 6600 kilometers between the cable landing stations in Virginia Beach, USA, and Saint-Hilaire-de-Riez, France. The transmission rate in 2021 was 400G. The trial also proved that the total link distance from Virginia Beach to Paris is 7345 kilometers, the transmission rate is 700Gbps, and the transmission rate in 2021 was 300G. The land fiber optic link part contains nine spans and multiple cascaded ROADM of Orange's existing optical network, using 150GHz WDM channels.
This field trial successfully verified the upgrade plan planned for Orange's long-distance network using Nokia's PSE-6s super-coherent photonic business engine, proving that the device can expand the capacity and spectral efficiency of existing submarine cable systems, and compared with existing coherent optical products, the number of required coherent optical devices is reduced by 33%, and the total power consumption is also reduced. The introduction of PSE-6s super-coherent capabilities in the Nokia 1830 PSS product family can achieve high-performance, high-spectral efficiency high-speed business transmission in long-distance, ultra-long distance, and transoceanic networks, with a transmission distance of up to thousands of kilometers.
Jean-Louis Le Roux, Vice President of Orange International Networks, said: "This trial shows that Orange is committed to supporting larger network scales and new high-bandwidth services in our existing global network, providing our customers with true global connections based on our submarine cable network. We are pleased to be the first operator to verify Nokia's latest generation of super-coherent optical technology in a submarine cable network. This technology has high spectral efficiency, sustainability, and operational deployment flexibility, which is an important means to meet our continuous network upgrade needs."
James Watt, Global President of Nokia's Optical Networks Business Division, said: "We are very pleased with the success of Nokia's high-performance PSE-6s in this trial and are honored to continue to work with Orange to support its network upgrade plan. As global data volumes continue to grow, innovation in optical networks is crucial to maintaining a leading position. The PSE-6s super-coherent photonic business engine injects strong power into Nokia's optical transmission product family, providing a large-scale optical network and business coverage, while ensuring sustainably optimized energy efficiency.
