چکیده
In this paper the analysis of Stimulated Raman Scattering induced crosstalk in Subcarrier Multiplexed WDM system has been discussed. The expression for SRS induced crosstalk have been observed for different fiber types such as single mode fiber, dispersion compensation fiber, non-zero dispersion shifted fiber and non-zero dispersion fiber. Comparison of different fibers is done at varying transmission length keeping the modulation frequency constant at 5 GHz. In general, it has been observed that that the SMF and DCF show the better results over span of the transmission length. The present work shows that out of four different types of fiber SMF and DCF have the minimum crosstalk range as (-82dB to -75dB) and (-70dB to -75dB) but DCF shows the fluctuation over the span of transmission length.
