The probability density function of Stimulated Raman Scattering (SRS) crosstalk for WDM systems with dispersion compensated links is studied and the parameters, mean power depletion and crosstalk variance, are derived. Contrary to the present papers, where these parameters are determined for the most affected channel, the expressions derived here are applicable for any channel. In addition, the presented analysis is more realistic in the sense that the SRS generated by the DCF is taken into account. The derived expressions facilitate in studying the effects of the modulation format (NRZ versus RZ) on the strength of SRS. The procedure of calculating the power penalty due to SRS and the optimum threshold are also presented.
