ABSTRACT:
A method for verifying fiber connections and diagnosing loss of light or loss of signal conditions in a WDM optical system. The method utilizes an optical time domain reflectometer (OTDR) having user-selectable wavelengths to shoot OTDR traces at a specified wavelength corresponding to an optical data-bearing channel into a selected one of a plurality of optical fiber transmission lines that are connected to a multiplexer that respectively multiplexes a data bearing channel carried on each of the plurality of optical fiber transmission lines onto a trunk, or a demultiplexer that demultiplexes multiplexed data bearing channels from the trunk. The OTDR receives backscattered light from the selected optical fiber transmission line and generates a trace of the backscattered light, thereby enabling a fault location in the WDM optical system to be determined from the trace.
