A method and apparatus for adaptive nonlinear equalization in a polarization multiplexing optical communication system, having a horizontal polarization compensation unit calculating a linear damage value of an input signal, a nonlinear damage value of a horizontal component of the signal, and a crosstalk value caused by a vertical component of the signal to the horizontal component of the signal, and compensate the horizontal component of the signal according to the damage values, and the crosstalk value; and, a vertical polarization component compensation unit calculating a linear damage value of the signal, a nonlinear damage value of a vertical component of the signal, and a crosstalk value caused by a horizontal component of the signal to the vertical component of the input signal, and compensate the vertical component of the signal according to the damage values and the crosstalk value. Intra-channel nonlinear damage is effectively compensated.
