Abstract :
A proposed configuration to monitor a wavelength division multiplexing (WDM) passive optical network (PON) with high quality in service is presented. This system composes of fiber Bragg gratings, an 1 times 4 optical switch and an optical time domain reflectometry to diagnose the broken points in real time. The scheme could simultaneously detect multi-optical network units in a WDM-PON. Remote pump integrated residual pumping reused function is implemented. Broken points in different optical paths can be detected simultaneously even the distances to central office are identical. Bit error rate testing is verified with small power penalty, making it an ideal solution for real-time monitoring in a WDM-PON.
