WDM guy here. Sure, 80 channels are space for lots of 400 Gb/s circuits... But we still fill cables and keep laying more. Though yes, the big 1288 fibers cables

WDM guy here. Sure, 80 channels are space for lots of 400 Gb/s circuits... But we still fill cables and keep laying more. Though yes, the big 1288 fibers cables aren't common. Also, lambdas don't terminate at every node - so sparse network topology implies that filling all channels on a single link is a merely theoretical situation.
