Abstract

Abstract This study has presented the nonlinear medium such as passive nonlinear medium like highly nonlinear fiber (HNLF) and active nonlinear medium like SOA. The FWM effects have ended up plainly huge at high optical power levels and have become even more meaningful when the capacity of the optical transmission line is increased, which has been reached through decreasing the channel separations. Also, anatomy has been done to analyze the performance of FWM when unequal channel spacing is considered. The outcomes indicate that when unequal channel spacing is used, the power levels of the beat frequency generated due to FWM effect in WDM system was increased to large values, so the performance of the wavelength division multiplexing (WDM) system is not enhanced, on the other hand when equal channel separations are used, and at the same bandwidth required to transmit 4 input channels the quality of receiving signal is greater than the system used unequal channel separation. This means that in the WDM system equal channels separation is more efficient than unequal channels separation-based SOA. The simulation is done using 4 channel wave division multiplexing signals at a rate of 10 Gb/s.
