ABSTRACT:
An optical attenuator is included within an aircraft decoy driver system for driving a fiber optic towed decoy system to compensate for variability in the fiber optic connection to the towed decoy system. The attenuator is controlled by a control signal from the towed decoy system and adjusts the link gain based on this feedback control signal to compensate for link loss, which is highly variable and may include losses as a function of cable, connectors and splices, and to maintain a relatively constant gain. To ensure the broadest range of performance, a higher power laser can be used to drive an external Mach Zhender Modulator or an erbium doped fiber amplifier (EDFA) prior to the optical attenuator. The result is a fiber optic towed decoy system that is adaptable to various platforms and design configurations without degradation in performance of the towed decoy system.
