ST/APC Singlemode Female-Male Fixed Fiber Attenuator options from 1-25dB
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.
Fixed Fiber Attenuators 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.
Bulkhead Female to Female Fiber Attenuators (look likes fiber adapter) is ideal for use in fiber optic patch panels, the instrument from panels, and other applications that require a fixed level of attenuation and easy connectivity.

How to Use Fiber Attenuators?
For female to male fixed fiber optic attenuators, we can plug the patch cord to the female fiber optic adapter of the attenuator. And then plug the male plug connector of the attenuator to the equipment directly. For female to female fixed fiber optic attenuators, we should plug the two patch cords to the two female fiber optic adapter of the attenuator (shown in the figure below).
