Patent ID: 8687979

Claim:
A device for generating a phase polarization modulated signal, comprising: a Laser Diode (LD), a time division demultiplexer, a phase precoding module, a phase modulating module, a polarization precoding module and a polarization modulating module, wherein the LD is configured to output an optical signal; the time division demultiplexer is configured to divide service data to be transmitted into first sub-service data and second sub-service data; the phase precoding module is configured to perform phase precoding processing on the first sub-service data, so as to obtain phase precoded first sub-service data; the phase modulating module is configured to phase modulate the phase precoded first sub-service data on the optical signal, so as to obtain a phase modulated first sub-service data optical signal; the polarization precoding module is configured to perform polarization precoding processing on the second sub-service data, so as to obtain polarization precoded second sub-service data; and the polarization modulating module is configured to perform polarization modulating processing using the polarization precoded second sub-service data on the phase modulated first sub-service data optical signal, so as to obtain a phase polarization modulated signal.
