摘要： The present invention discloses a receiving apparatus, a sending apparatus, a system and a method for optical polarization division multiplexing. The receiving apparatus includes: an optical splitter, configured to: split a received polarization-multiplexed optical signal into two identical polarization-multiplexed optical signals, where the two polarization-multiplexed optical signals both include a first State Of Polarization (SOP) optical signal and a second SOP optical signal, and the first SOP optical signal is an optical signal when a horizontal-SOP optical signal is transmitted to the optical splitter, and the second SOP optical signal is an optical signal when a vertical-SOP optical signal is transmitted to the optical splitter; a horizontal optical signal obtaining apparatus, connected to the optical splitter and configured to separate the horizontal-SOP optical signal; and a vertical optical signal obtaining apparatus, connected to the optical splitter and configured to separate the vertical-SOP optical signal.

摘要： The embodiments of the present invention disclose a system, a method, and a device for polarization multiplexing. The method includes: co-direction judgment: after judging that the similarity between the control quantities of the two optical signals meets a predetermined similarity criterion, enabling at least one of the two branches to re-search for the control quantity until the similarity between the control quantities of the two optical signals does not meet the predetermined similarity criterion. The preceding technical solution may substantially prevent the optical signals output by the two branches at a receiving end from having the co-directional state of polarization, without affecting the complexity and implementation cost of the system and the processing time delay of data signals at the receiving end.
