RECEIVER, SENDING DEVICE, SYSTEM OF OPTIC-DEMODULATION OF POLARIZATION MULTIPLEXING AND METHOD THEREOF

摘要

A receiver, a sending device, a system of optic-demodulation for polarization multiplexing and a method thereof are disclosed. The receiver includes: beam splitter, which divides received optical signal for polarization multiplexing into two same optical signals for polarization multiplexing; these two same optical signals for polarization multiplexing both include a first polarization optical signal and a second polarization optical signal respectively; the first polarization optical signal is optical signal when the optical signal with horizontal polarization is transmitted to the beam splitter; the second polarization optical signal is optical signal when the optical signal with vertical polarization is transmitted to the beam splitter; an acquisition device for horizontal optical signal, which is connected with the beam splitter, for detraining the optical signal with horizontal polarization; an acquisition device for vertical optical signal, which is connected with the beam splitter, for detraining the optical signal with vertical polarization. The crosstalk of optical signals is reduced; the performance of optical transmission system for optic-demodulation of polarization multiplexing is improved.
