PROBLEM TO BE SOLVED: To reduce signal waveform deterioration generated by a nonlinear optical effect in wavelength division multiplex transmission.;SOLUTION: The optical transmitter in a wavelength division multiplex transmission system has a light source which generates light with a plurality of wavelength in which phases of light are synchronized and a compensation means for compensating waveform deterioration of the light of each wavelength generated by the nonlinear optical effect of a transmission path. The compensation means estimates the waveform deterioration on the receiving end to compensate the waveform deterioration based on transmission path parameters such as the transmission parameters. Otherwise, the compensation means estimates the waveform deterioration generated in the transmission path by the nonlinear optical effect by using a transmission data pattern of other wavelength. Furthermore, the compensation means estimates phase variation generation in the transmission path by the nonlinear optical effect based on optical field intensity to compensate the waveform deterioration by the phase variation.;COPYRIGHT: (C)2008,JPO&INPIT
