摘　　要：讨论了二阶偏振模色散对光脉冲的影响,模拟结果表明,二阶偏振模色散对信号影响起主要作用的是去偏振项,使得信号波形边缘出现能量过冲;同时也讨论了二阶偏振模色散补偿的方法,利用二段偏振模色散补偿器对二阶偏振模色散进行了有效的补偿,并给出了补偿的实验结果。The influences of second order PMD on light pulse are discussed. The results by number simulation show that the second-order polarization mode dispersion (PMD) components associated with depolarization of the principal states can cause significant system impairments. By the same time the compensation method for second-order PMD are also discussed by theoretically and experimentally. The experiment results show that it is very effective to compensate second order PMD by using two stage PMD compensator.
