A method for optimizing parameters between two optical coherent transceivers connected via an optical link, the method comprising:
- operating the two optical coherent transceivers using a set of parameters;
- wherein data transmission between the two optical coherent transceivers is coherently encoded on one or more optical signals;
- determining performance based on the set of parameters;
- determining a side channel communication to update the set of parameters;
- and
- modulating an amplitude of the one or more coherently encoded optical signals transmitted across the optical link to encode a side channel information by a respective optical coherent transceiver for the side channel communication;
- wherein data is transmitted through the coherent encoding of the optical signal and the side channel information is encoded on the amplitude of the coherently encoded signal enabling contemporaneous transmission of data and the side channel information.
