We extend the functionality of the nonlinear amplifying loop mirror (NALM) to a multi-channel RZ WDM system by demonstrating the NALM as a single module for amplification and background noise suppression for four WDM data channels simultaneously. The NALM itself consists of an Er-doped fiber amplifier (EDFA) (70 mW saturated power) placed at one end of a 500 m long length of single mode fiber (SMF) and joined in a loop by a 3dB fiber coupler.
