The probability density function of four-wave-mixing crosstalk in wavelength-division-multiplexing systems is derived analytically in a closed-form formula. For dispersion shifted fiber the plots were given for different number of channels, different channel indexes and different channel spacings. The comparison with Gaussian approximation is given, and the limits of its application are pointed out.
