| 摘 要： | 近年来，为满足日益增长的带宽要求，光纤通信得到了长足发展。为了研究色散（PMD）对光纤传输的影响，从而最大限度的提高系统可用带宽。首先提出了运用统计的方法来计算这种随机的色散值，在此基础上，用MATLAB中的模拟块依据统计的结论作了信道仿真，得到了用图形说明的PMD导致的波形失真，计算出工程用G．652光纤最大的无中继传输距离。依据色散散特给出了一阶偏振模色散的一种补偿方法，为今后的偏振模色散补偿提供了一种思路。

| Abstract: | In recent years, to satisfy the increasing need of the band of transmission, great progress has been made in the fiber communication. In order to study the PMD's effects on fiber transmission system and to increase the transmission speed, a statistical method to estimate the PMD value is provided firstly, and based on this, the PMD channel with models in MATLAB is simulated. As a result, the distortion waves caused by PMD are obtained and the maximum no relaying distance of G 652 fiber is worked out. Finally a first order polarization mode dispersion compensation system is presented according to the character of PMD and a new way for future PMD compensation is put forward. |
