Arelion and Nokia complete 500 km coherent-optics field trial
Arelion said it completed a live-network trial between Amsterdam and London using Nokia's Super C and Super L open-line system and 400G/800G ZR+ coherent pluggable optics. The company reported about 21% more usable optical spectrum on the route. This is a trial result, not an announcement of a network-wide rollout.
