We provide a theoretical (signal and noise) and an experimental characterization of the nonrecirculating and the recirculating fiber-optic delay-line filters that include one fiber loop. Signal and noise analysis for passive and active operation are presented, and measurements of both the filter modulus and the phase are presented, showing good agreement with results predicted by the theory.
