摘要

In order by the fact that the polarized wave multiplex BPSK signal optical phase is modulated pseudo in the polarized wave multiplex QPSK signal, to do the polarized wave separation of the polarized wave multiplex BPSK signal in the reception circuit whose scale is small, using the lightwave signal polarized wave multiple to be done, being the optical communication system which it communicates, modulating the phase of the multiple lightwave signals to be the BPSK modulation technique which includes the information which it should communicate, the polarized wave separating the polarized wave multiple lightwave signals multiple to be done from the optical phase modulation section which generates the multiple lightwave signals to become pseudo QPSK modulation technique and the multiple lightwave signals to be modulated in pseudo QPSK modulation techniqueIt features that it has the signal return which reconstructs the information which it should communicate and.
