An optical system that maximizes signal quality related to spectral shape of an optical signal includes a light source module, a light receiver module, a plurality of fixed optical filters and a tunable optical filter. The light source module includes a light source that provides an optical signal to an optical fiber that includes a plurality of optical fiber segments. The light receiver module includes a receiver input that receives the optical signal from one of the plurality of the optical fiber segments. The plurality of fixed optical filters filter the optical signal and are coupled between the light source module and the light receiver module by the plurality of optical fiber segments. The tunable optical filter includes a control input, a filter input and a filter output. The filter input receives the optical signal and the filter output provides a filtered optical signal. A center filter frequency of the tunable optical filter is varied to maximize signal quality exhibited by the filtered optical signal responsive to a control signal on the control input.
