A cascaded Kalman filter fiber channel damage adaptive equalization processing optimization algorithm，which is based on the multiple input multiple output constant module algorithm（MIMO-CMA）is proposed to address the issues of excessive rotation of state of polarization（RSOP）speed，polarization mode dispersion（PMD），residual chromatic dispersion，polarization dependent loss（PDL），residual carrier frequency offset（CFO），and carrier phase noise（CPN）that seriously affect communication quality in extreme conditions of optical fiber polarized light signals.Firstly，the quadrature phase shift keying（QPSK）signal containing various optical fiber channel impairments is balanced using MIMO-CMA to achieve residual dispersion and preliminary polarization effect related impairments.Then，the Kalman filter is adopted to balance the residual RSOP damage，CFO，and CPN.Simulation results show that the constellation recovery effect of the input signal after the equalization of the optimization algorithm is good，and the trackable RSOP speed can reach over 9Mrad·s-1，and can effectively reduce the computational complexity of the algorithm.
