Abstract

The optical performance monitoring method using asynchronous amplitude histograms was introduced. Its capability to monitor both SNR and waveform distortion due to chromatic dispersion was experimentally confirmed using a 10 Gbit/s optical NRZ signal, and bit-rate flexibility from 10 to 160 Gbit/s optical RZ signal was also discussed. This method is intrinsically flexible with respect to the signal format and modulation format, and is a useful candidate for optical signal quality monitoring in optical networks in the future.
