摘要

In order to expand the capacity of optical fiber communication system the most important phenomena is the emergence of dense wavelength division multiplexing (DWDM). Using DWDM, multiple channel of information can be transmitted on single fiber. There are some limiting factors related to data rate and capacity in DWDM optical fiber communication system. These limiting factors can be linear or non-linear. We can compensate the linear effect such as dispersion and attenuation by using pulse having right shape called soliton but the non-linear effect accumulate. The most important non-linear effect occur in the fiber optics communication system are Self phase modulation(SPM), stimulated brillouin scattering (SBS), Cross phase modulation (XPM), Four wave mixing (FWM) and Stimulated Raman scattering (SRS). These non linear effects are the most important limiting mechanism to the capacity of optical fiber communication system. Self phase modulation (SPM), Stimulated brillouin scattering (SBS) occurs only in single channel fiber optics communication system and Cross phase modulation (XPM), Four wave mixing (FWM), Stimulated Raman scattering (SRS) have impact on multichannel DWDM fiber communication system. In this paper, we analyze the impact of cross phase modulation (XPM), Four wave mixing (FWM), stimulated Raman scattering (SRS) on DWDM communication system at different power level & different number of data channels. We also describe some novel technique to reduce the effect of these non linearities (XPM, FWM, SRS) in DWDM fiber communication system. For simulation we use OptiSystem software.
