Realization of auxiliary management and control channel in WDM-PON based on DBPSK re-modulation and delay interferometer detection

Dianxin kexue, 2018
In WDM-PON,the OAM data path and user data path were independent in the TC layer.The OAM data could be transmitted either transparently or by codec.Specifically,the transparent mode was preferred by the industry network due to the free of codec and low ...
