1. An optical communications network, comprising:

  • a transmitter, further comprising;

    a forward error correction (FEC) encoder;

    a precoder; and

    a modulator;

    a receiver, further comprising;

    a detector;

    a FEC decoder;

    a decision block; and

    an error check block; and

    an analyzer configured to generate nonlinear statistics of an optical channel between the transmitter and the receiver, and adapting the encoder, the precoder and the modulator, individually or in any combination to the nonlinear statistics.
