| Abstract: | Used the split step Fourer algorithm to solve the coupled nonlinear schrodinger equation in birefringent fibers,the influence of polarization mode dispersion (PMD) is numerically calculated.Through numerical simulation it is found that the influence of polarization mode dispersion to communication system can be effectively reduced by synchronous modulation. |

| Keywords: | Polarization mode dispersion Principal states of polarization Random birefringence Synchronous modulation |
