摘要：

This letter describes fault localization in the optical wavelength-division-multiplexing (WDM) submarine cable networks by coherent-optical time domain reflectometry (C-OTDR), Using the bidirectional system designed for WDM signal transmission and a wavelength add/drop branching unit [add/drop brancing unit (BU)] circuit, the trunk path, the branch path and the add/drop BU circuit were successfully surveyed by C-OTDR with wavelength tunability, It is very effective to conduct fault localization even in the optical WDM submarine cable networks by the same way as in the conventional single-channel systems.
