<p>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.</p> |
