In a recent trial, Nokia and Orange used the Nokia PSE-Vs, the vendor’s fifth generation super coherent optics, to support end-to-end 400 Gbps services across the carrier’s network.

The trial was performed in real-world conditions and over a 914 km network between Paris and Biarritz. The fiber network consisted of 13 spans of Orange’s existing network, through multiple cascaded reconfigurable optical add/drop multiplers (ROADM), using 100-GHz WDM spectrum channels.

According to Orange, the results of the trial validated its plan to upgrade its long-haul backbone networks to support new high-bandwidth 400 Gbps services, and the ability to scale fiber capacity up to 600 Gbps.
