Abstract
An inservice supervisory 10-Gb/s dense wavelength-division-multiplexing (DW DM) system containing Mach-Zehnder fiber Bragg grating (MZ-FBG) optical add -drop multiplexers (OADMs) is demonstrated. The link fault location is real ized simply by using a conventional optical time-domain reflectometry (OTDR ) directly through the used MZ-FBG OADM without needs of restructuring OADM configuration and extra optical components in the OADM node. The 1.65-mum. OTDR supervision on such 10-Gb/s 80-km system link is achieved without deg rading the system performance.
