| 1. A towed decoy communications system, comprising:
a laser signaling system operable to generate an optical signal for a towed decoy;
an erbium doped fiber amplifier (EDFA) coupled to the laser signaling system that amplifies the optical signal for application
to at least one towed decoy; and
an optical switch coupled to the EDFA operable to convey the amplified optical signal to the at least one towed decoy;
wherein the EDFA operates in saturation mode and produces a constant output power to compensate for attenuation of fiber optic
connections to the towed decoy.
