摘要: An apparatus for mitigating polarization dependent loss (PDL) in an optical signal-to-noise ratio (OSNR) of a modulated signal is disclosed. The may comprise spectrum analyzer to measure power signal. also measuring unit select first portion the and second signal, where each portions signals include independent noise distribution indicative PDL, time-varying parameter portions. processor PDL OSNR by transforming any elliptical associated with into ball polarization, determining correlation between parameters portions, calculating mitigated OSNR.
