The simulation studies are carried out using optisystem software from optiwave. The performance of improved detected signals has been evaluated by the analysis of Quality factor and bit error rate (BER). we use the dispersion compensation fiber along with single mode fiber (SMF) for length of 100km at 1550nm to reduce the dispersion of optical signal. In this paper we analyze the performance of Dense Wavelength Division Multiplexing (DWDM) based fiber optic communication system at different modulation schemes, various power level and different number of data channels. They are Cross phase modulation (XPM), Self phase modulation (SPM), four wave mixing (FWM), stimulated brillouin scattering (SBS) and stimulated Raman scattering (SRS). The performance of DWDM is degraded by non-linear optical effects. This technology utilizes a composite optical signal carrying multiple information streams. Abstract Dense Wavelength Division multiplexing (DWDM) is a novel technology that can improve the channel capacity and meet growing demands for bandwidth of the optical fiber communication system.
