Abstract:
Apparatus and method for digital signal constellation transformation are provided herein. In certain configurations, an integrated circuit includes an analog front-end that converts an analog signal vector representing an optical signal into a digital signal vector, and a digital signal processing circuit that processes the digital signal vector to recover data from the optical signal. The digital signal processing circuit generates signal data representing a signal constellation of the digital signal vector. The digital signal processing circuit includes an adaptive gain equalizer that compensates the signal data for distortion of the signal constellation arising from biasing errors of optical modulators used to transmit the optical signal.

Claim (Index 12):
A method of operating a network comprising:\n in integrated optical module, receiving, by a coherent optical receiver, an optical signal from an optical cable of the integrated optical module; generating, by the coherent optical receiver, an analog signal vector representing the optical signal; processing, by a transceiver, the analog signal vector to generate a digital signal vector, wherein the digital signal vector comprises a digital representation of an in-phase (I) component and a quadrature-phase (Q) component of the optical signal; and generating, by the transceiver, signal data representing a signal constellation of the digital signal vector; wherein generating the signal data comprises\n generating, by an adaptive gain equalizer of the transceiver, transformed signal data by compensating the signal data for distortion of the signal constellation, \n compensating, by the adaptive gain equalizer, for distortion for a first portion of the signal data associated with a horizontal polarization of the optical signal, and \n compensating, by the adaptive gain equalizer, for distortion for a second portion of the signal data associated with a vertical polarization of the optical signal; and \n transferring an outgoing optical signal.
