An integrated coherent receiver that is configured to receive an optical signal and receive a local oscillator (LO) source from a remote location. The integrated coherent receiver is configured to extract phase and frequency information carried by the optical signal using the LO source from the remote location.

Coherent detection with remotely delivered local oscillators

An optical transceiver in an optical communications network, comprising a receiver configured to receive an optical signal comprising an X-polarization component that comprises a first frame and a Y-polarization component that comprises a second frame. The optical transceiver also comprises a processor coupled to the receiver and configured to determine, in a time domain, a phase estimate according to the first frame and the second frame, determine, in a frequency domain, a channel estimate for the optical signal according to a relationship between the first frame, the second frame, and the phase estimate, and determine a compensated optical signal according to the channel estimate. The optical transceiver further comprises a transmitter coupled to the processor and configured to transmit the compensated optical signal to a downstream component in the optical communications network.
