Fiber optic attenuators are used in the fiber optic links to reduce the optical power at a certain level. We supply various kinds of fiber attenuators, including LC, SC, and ST, FC and Variable fiber optic attenuators.
 

Commonly used fiber optic attenuators are the female to male type, which is also called a plug fiber attenuator. They are with ceramic ferrules and there are various types to fit different kinds of fiber optic connectors. Fixed value fiber optic attenuators can reduce the optical light power at a fixed level, for example, a 10dB SC fiber optic attenuator will reduce the optical power 10dB and utilize a SC male to female attenuator.  Variable fiber optic attenuators are with adjustable attenuation range. There are also attenuation fiber optic patch cables available, their function is same as attenuators and are used inline.
