摘要： A method, device, system for realizing polarization mode dispersion (PMD) compensation are provided. The method for realizing PMD compensation includes: de-multiplexing a polarization-multiplexed optical signal, to obtain a first polarization light and a second polarization light; and joint-equalizing the first polarization light and the second polarization light, to obtain a first equalization signal and a second equalization signal. Since the polarization-multiplexed optical signal is de-multiplexed and then joint-equalized, not only the intra-channel symbol interference but also the inter-channel symbol interference during transmission of the polarization-multiplexed optical signal is eliminated, so as to realize the PMD compensation.
