Orange said that it has successfully validated a planned upgrade of its long-haul backbone network to support new high-bandwidth 400 Gbps services. The development was the result of a field trial in real-world conditions of Nokia’s Photonic Service Engine V (PSE-V) and production-ready optical transport hardware.
PSE-V, Nokia’s fifth generation coherent digital signal processor family, enables spectrally efficient transport at up to 600 Gbps. In the trial, spectral efficiency improved by 50 percent compared to what Orange could previously expect on its long distance infrastructure.
The demonstration achieved error-free performance at a data rate of 600 Gbps over a 914 km network between Paris and Biarritz. It was carried out sixteen months after a laboratory prototype trial completed on Orange’s live network.
With ‘super coherent’ DSP (Digital Signal Processing), PSE-V is part of Nokia’s family of digital coherent optics (DCO). It belongs to the WaveFabric Elements portfolio of photonic chips, devices and subsystems, unveiled by the Finnish equipment maker in May 2020.
