The growth of the four-wave mixing (FWM) near the zero-dispersion wavelength (ZDWL) is analyzed in wavelength-division multiplexing (WDM) solitons systems. The phase-matching conditions lead to a slight reduction of the frequency offset. Numerical analysis of the reduced model predicts a variation of appearance of the FWM along the transmission line, and comparison of the FWM crosstalk is presented in the case of well-separated input channels approximation. Considering the full model, the FWM decreases along the transmission line. For long distances, an analytical asymptotic solution of the FWM is used and confirms this feature beyond the tenth amplification node.
