Experimental Measurements of the Effectiveness of MLSE against Narrowband Optical Filtering Distortion

We experimentally investigate the application of MLSE-EDC to signals transmitted through narrowband optical filters. We find MLSE affords significant OSNR improvement of ~5 dB for NRZ signals, but less or none for duobinary and DPSK.
