The purpose of a fiber optic attenuator is to reduce the optical power level of a signal traveling through a fiber optic cable. Its primary function is to prevent receiver overload, which can occur when the received optical power is too high for the receiver to handle. Receivers have a specific input power range within which they can operate reliably. If the received power exceeds the maximum input power, the receiver can become saturated, leading to distortion and errors. Attenuators are used to reduce the powe....
