Field trial demonstration of novel optical superchannel capacity protection for 400G using DP-16QAM and DP-QPSK with in-service OTDR fault localization
A novel optical superchannel protection scheme is proposed and successfully demonstrated over field fiber links for 400G capacity using main 400G DP-16QAM and protection 400G DP-QPSK superchannels together with in-service OTDR fault localization.
