Stimulated Raman Scattering (SRS) effect is one of the Nonlinear effects in Dense Wavelength Division Multiplexed (DWDM) Fiber Optic Communication System. The effect of Stimulated Raman Scattering causes power to be transferred from the lower wavelength channel to the higher wavelength channel. This will reduce the Optical Signal to Noise Ratio (OSNR) for the high frequency channel or low wavelength channel. SRS effect is studied for different input power and for different number of wavelengths. SRS effect could be reduced by setting optimum optical power in the fiber. Various channel (4,8,11) DWDM system for various power levels of individual channels is stimulated in the sample mode of OPTSIM software for getting the effects of SRS like Power Tilt in the optical spectrum, after the fiber.
