Abstract

In this paper, we propose a novel method to depict 2-dimension (2-D) phase portrait by using single-channel-sampling (SCS) technique, which can be used for optical performance monitoring. Single low speed sampling scheme reduces cost and complexity of monitoring system setup significantly. In the experimental demonstration, optical signal to noise ratio (OSNR) is monitored from 10 dB to 30 dB by statistical analysis on pattern evolution of the generated 2-D phase portrait in both NRZ and RZ systems. The chromatic dispersion (CD) influence on OSNR monitoring performance is also investigated.
