What Are Fiber Optic Attenuators?
Fiber optic attenuator, also called optical attenuator, is a passive device used to reduce the power level of an optical signal. Owing to that too much light can make a fiber optic receiver saturated, the light power must be reduced by using fiber optic attenuator to achieve the best fiber optic system performance.
