This successful record test validates Orange network infrastructure’s capability on transatlantic submarine cable to support 400GE and 800GE (Gigabit Ethernet) transport services over its entire network.
To prepare for the expected traffic surge on the transatlantic route, Orange and Nokia have successfully tested Nokia’s sixth-generation super coherent optical technology (PSE-6) in real-life conditions on this strategic axis.
800 Gigabits per second were achieved on the 6,600km Dunant transatlantic submarine cable and terrestrial backhaul, on an existing fiber pair carrying customer traffic, which will eventually enable wholesale and enterprise customers to benefit from capacity of up to 400GE and 800GE.
These tests validate the transport of 800 Gigabits of traffic per wavelength, demonstrating the possibility of almost doubling the range, extending the capacity transmitted and optimizing spectral efficiency on an existing infrastructure. Orange and Nokia regularly carry out full-scale tests on Orange’s long-distance and international network to test their latest-generation super coherent optics technology.
Jean-Louis Le Roux, Vice President International Networks at Orange, said: “This trial demonstrates Orange’s commitment to supporting ever-greater network scale and new high-bandwidth services across our existing global network, which combined with our subsea networks truly powers global connectivity for our customers. We are pleased to be the first operator to validate Nokia’s latest generation of super coherent optics in a subsea application as an important enabler to our constant need for network upgrades, with high spectral efficiency, sustainability and operational deployment flexibility.”
