A process for tunable filter train alignment comprises detecting a spectral response of the filter train and aligning an optical fiber that transmits an input optical signal to the filter train during operation. Further, the tunable filter is moved relative to the filter train in response to a spectral response of the filter train. As a result, the alignment and spectral response of the tunable filter train are optimized. In the preferred embodiment, the alignment and SMSR optimization occur simultaneously with respect to each other.
