Abstract: This Paper deals with the analysis of the performance limitation of SMF (single mode fiber) due to nonlinear effect. With the help of optsim simulation software a combination of SMF and DCF (dispersion compensation fiber) has been simulated with a proper variation in length to tackle the effects in the transmission system. Better performance was shown when a combination of SMF length 90Km and DCF length 10km was chosen. The Q-value and BER technique has been used for show the system performance.

Keywords: Chromatic dispersion, DCF, Nonlinear effect, SMF, FWM.
