Abstract :
Cross-phase modulation (XPM) is a dominant impairment in WDM networks employing high bit-rates and narrow channel spacing. The optimization of future networks requires rapid and accurate techniques to predict XPM-induced penalties. We demonstrate the accuracy of predicting penalties from the distortion of a CW probe channel and show that as a consequence, XPM penalties can be calculated by a simplified numerical technique.
