    • Provided are a polarization mode dispersion (PMD) compensator and method for automatically and rapidly compensating PMD occurring in an optical transmission fiber in a high-speed optical transmission system. The polarization mode dispersion compensator includes a separator and a differential time delay remover. The separator aligns orthogonal first and second polarization components of a received optical signal with respect to two orthogonal axes of a polarization beam splitter using optical signal information output via a second path of a first path and the second path of the two outputs of the polarization beam splitter, splits the first and second polarization components, and transmits the first polarization component via the first path and the second polarization component via the second path. The differential time delay remover receives the first and second polarization components that have been split to remove a differential time delay between the first and second polarization components.
    • 提供了一种用于自动快速补偿在高速光传输系统中的光传输光纤中发生的PMD的偏振模色散(PMD)补偿器和方法。 偏振模色散补偿器包括分离器和差分时间延迟去除器。 分离器使用经由第一路径的第二路径输出的光信号信息和偏振束的两个输出的第二路径,使接收的光信号相对于偏振分束器的两个正交轴的正交第一和第二偏振分量对准 分离器,分离第一和第二偏振分量,并且经由第二路径经由第一路径和第二偏振分量发送第一偏振分量。 差分延时去除器接收已经被分离以消除第一和第二偏振分量之间的差分时间延迟的第一和第二偏振分量。
