1. A method comprising:
generating, by a component of a coherent optical transceiver, an impairment within the coherent optical transceiver;
generating, by the coherent optical transceiver, a light signal from an electrical signal, the light signal having a wavelength of light encoded with coherent optical data impaired by the impairment;
transmitting, by the coherent optical transceiver, the light signal from an output of the coherent optical transceiver to an input of the coherent optical transceiver;
removing, by the coherent optical transceiver, the impairment in the light signal; and
recovering, by the coherent optical transceiver, the wavelength of the light encoded with the coherent optical data.
