分析并通过实验验证了光纤通信系统中偏振模色散引起的脉冲展宽对接收信号频谱的影响 ,在此基础上提出了一种偏振模色散的补偿技术。在 10Gbit/s的传输线路中实现了一阶偏振模色散 (PMD)的自动补偿。
The influence of the pulse broadening caused by the polarization mode dispersion in the optical fiber communication system on the spectrum of the received signal is analyzed and verified through experiments. On this basis, a compensation technique of polarization mode dispersion is proposed. In the transmission line of 10Gbit / s, the first-order polarization mode dispersion (PMD) is automatically compensated.
