A system receive, from an optical receiver, a signal derived from a first optical signal and a second optical signal generated by a local oscillator, that includes a first component that is an in-phase component and a second component that is a quadrature phase component; filter the signal, using a filter, set to one or more configurations, to obtain one or more recovered signals, where each of the recovered signals includes a respective quantity of noise; perform forward error correction, on the recovered signals, to obtain one or more quantities of bit errors that correspond to the recovered signals; and process the signal using the filter set to a particular configuration, of the one or more configurations, that corresponds to a lowest quantity of bit errors of the one or more quantities of bit error. |
