Orange tests Nokia PSE-V coherent engine performance over pan-European fiber backbone network

July 9, 2020

The three-week exercise, concluded last month, saw high-speed coherent transmissions from the PSE-V run alongside commercial traffic on the Orange International Networks Infrastructures and Services (OINIS) pan-European backbone.

Orange and Nokia say that they conducted successful long-haul coherent transmission trials using Nokia’s Photonic Service Engine (PSE-V) chipsets (see “Nokia unveils WaveFabric Elements DSPs, optical engines starting at 400G”). The three-week exercise, concluded last month, saw high-speed coherent transmissions from the PSE-V run alongside commercial traffic on the Orange International Networks Infrastructures and Services (OINIS) pan-European backbone.

The test routes ran from a network node in Paris to 15 points of presence (PoPs). The trial saw the creation of 400-Gbps services on fiber links up to 3400 km. The collaborators also demonstrated transmission of up to 600 Gbps with spectral efficiency of more than 6 Gbps/GHz over paths longer than 1000 km. The test proved the efficacy of significantly increasing the transmission rates that the pan-European backbone could support, including 27 Tbps on a single pair of fibers between such major hubs as Paris and Lyon, say the companies.

“At OINIS, we continuously benchmark our vendors’ technology advances in real-life scenarios to make sure every new development can consistently translate into tangible benefits for our customers,” commented Jean-Luc Vuillemin, executive vice president at OINIS. “Fifth-generation chipsets seem promising as another step towards a more efficient, cost-effective, and environmentally sustainable network, which combined with submarine networks truly connects the whole world.”

“We are delighted to showcase and field-proof the breakthroughs of our new generation chipset and its improved probabilistic algorithms (PCS 2.0) over the network of OINIS. These tests validate our strategy to optimize around the best tradeoff between spectral efficiency, reach, power consumption and overall cost, which today means making 400G ultra long haul and 600G regional a reality,” added Sam Bucci, senior vice president and general manager, optical networks at Nokia.
