Abstract
Optimization systems and methods are described configured to optimize filter coefficients in pulse shaping filters in transmitters and matched filters in receivers to maximize Q-factor in a fiber optic system. The systems and methods include receiving a measured Q-factor for one or more channels; iteratively adjusting filter coefficients of the pulse shaping filters and the matched filters to maximize a measured Q-factor of a channel of the one or more channels; and setting the filter coefficients of the pulse shaping filters and the matched filters to optimized values based on the iteratively adjusting.
