Abstract :
In this study, we introduce the third nonlinear optical effect known as four-wave mixing (FWM), its implications in optical fiber systems and finally a proposed technique for channel allocation to reduce its effect. Then, we investigate the channel crosstalk due to the FWM for various values of: fiber length, core effective area, dispersion, channel spacing and channel power as a function of the number of multiplexed channels in a multi-channel system. Results show that, the ultimate factor, which degrades the system performance, is the FWM power
