Performance of chromatic dispersion monitoring using statistical moments of asynchronously sampled waveform histograms

Abstract

The performance of the chromatic dispersion monitoring method using statistical moments of asynchronously sampled waveform histograms is investigated in detail. We show its robustness against signal-to-noise ratio degradation and its wide monitoring range using experiments and a newly developed numerical simulation method. We also show the effectiveness of radio frequency bandwidth reduction of the waveform monitor to widen its monitoring range, and also estimate its performance with duobinary and return-to-zero modulation formats.
