The system and method of the present invention is operative to monitor the performance of an optical communications channel. An optical splitter (14) splits a wavelength division multiplexed (WDM) optical communications signal into a low power WDM signal onto a back-up path (22), where a tunable filter (24) sweeps the optical communications channels, while a monitoring circuit (24) monitors the optical communications channels for performance. Optical power can be stored and subsequently displayed, providing an optical spectrum analysis of the signal.
La présente invention concerne un système et un procédé permettant de surveiller la performance d'un canal de communication optique. Un diviseur optique (14) divise un signal de communication optique multiplexé en longueur d'onde (WDM) en un signal WDM de faible puissance sur un chemin de secours (22) où un filtre réglable (24) balaie les canaux de communication optique, un circuit de surveillance (24) surveillant la performance des canaux de communication optique. La puissance optique peut être stockée puis visualisée, d'où la réalisation d'une analyse du spectre optique du signal.
