<p><a href="http://www.osa-jon.org/features/OPM_2004.html">Feature Issue on Optical Performance Monitoring (OPM)</a></p> An effective technique to monitor the quality of wavelength-division-multiplexed (WDM) channels is presented. This process uses a blind signal separation (BSS) method based on higher-order-statistics (HOS), and an optical-loop structure to extract the baseband channels from the WDM transmission. From the reconstructed baseband waveforms, a series of WDM transmission quality parameters are evaluated. Relative to previously proposed methods for WDM-channel monitoring, the HOS-based optical-loop procedure shows reduced complexity, improved cost efficiency, and better performance.
