The coupled-mode equations based on data-pump degenerate four-wave mixing (FWM) are presented for multi-wavelength regeneration. The equalization method using quasi-phase-matching is put forward for time-interleaved wavelength channel regeneration. Starting from optimizing the phase-mismatch factors of degenerate FWM, the equalization and regeneration of fixed or arbitrary four wavelengths are realized by the optimization of wavelength distribution or the fiber parameters, respectively. The calculations show that the variations of output peak power, extinction ratio (ER) and Q factor for the equalized channels are less than 0.25 dB, 0.42 dB and 1.5, respectively.
