Abstract

An inservice supervisory 10-Gb/s dense wavelength-division-multiplexing (DWDM) system containing Mach-Zehnder fiber Bragg grating (MZ-FBG) optical add-drop multiplexers (OADMs) is demonstrated. The link fault location is realized 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-μm OTDR supervision on such 10-Gb/s 80-km system link is achieved without degrading the system performance.
