The signal amplitude transmission model of polarization field coupled with the polarization mode coupling effect is proposed, and then the expression of the signal field amplitude transfer matrix and the amplitudes of the received signal field are obtained. The results of the existing experiments , The physical meaning of the model is pointed out. According to two different thresholds of receiver decision, the systematic error characteristics of the system are affected by the polarization mode dispersion in the presence of polarization mode coupling effect. The results show that the polarization mode dispersion After more than 10% of the signal symbol interval will significantly deteriorate the system’s error characteristics
