We present a practical method of monitoring system performance of WDM signals. The method is based on an intelligent combination of optical and electrical signal processing. The photocurrent of a detected (multi-channel) optical signal is analyzed using an adaptive signal separation method. A maximum data decorrelation criterion is used to separate the WDM channels from a set of multi-channel photocurrents. Although this chapter shows an accurate separation of four WDM channels, we believe that this method can also be applied for monitoring a larger number of WDM channels.
