Fiber attenuators, also called optical attenuators, are passive devices used to reduce the power level of an optical signal. Since too much light may saturate the fiber optic receiver, optical attenuators are often deployed in the system to reduce the light power and achieve the best fiber optic system performance.
Generally, multimode systems do not need attenuators as the multimode sources, even VCSELs, rarely have enough power output to saturate receivers. Instead, for single-mode systems, especially the long-haul DWDM network links, fiber optic attenuators are necessary for balancing the optical power during the transmission.
This FC/APC single mode fiber attenuator is a male to female type of fiber optic attenuators that enable them to accept standard fiber optic connectors on each side of the bulkhead (also named as fiber adapter).
