Abstract

In WDM systems, the impact of fiber nonlinearity can be detrimental: four wave mixing (FWM), cross phase modulation (XPM) and parametric gain (PG) are the main causes. Whereas FWM, XPM and single channel PG have been extensively studied, the PG impact on WDM systems was not yet investigated in detail. The purpose of the work is the analysis of PG in a WDM environment. In this case, WDM signals propagate along an amplified fiber link, and optical carriers may act as pumps and generate spectral regions where ASE noise may experience gain, thus potentially degrading system performance
