Summary:Provided is an operation method of a coherent optical reception system. The operation method includes the following configurations. A coherent optical receiver configured to receive light from at least two light sources; a local oscillator (LO) configured to transmit first LO light to the coherent optical receiver, and a polarization controller configured to transmit a signal for polarization control to the LO, wherein the polarization controller is configured to transmit a first control signal to the LO on the basis of a first reception signal, and the LO is configured to transmit second LO light to the coherent optical receiver on the basis of the first control signal.
