In some cases when building and operating telecommunication fiber optic network, operator need to reduce or balance the power of the optical light transmitted from one device to another one, fiber optic attenuators are widely used for such applications, they are able to control, reduce, the output power of fiber light to a certain level depending on attenuator dB value. We supply several types fiber optic attenuators,  fixed value fiber optic attenuator – refer to the attenuator that can reduce the power of fiber light at a fixed value loss, for example, 10dB. All fixed ATT can be divided on several groups: Male to Female FM, Female to Female FF, In-Line type – certain length of a fiber optical cable with special  attenuation fiber and  connectors on both sides. While adjustable, or so called variable  fiber optic attenuator, refer to the attenuator that can adjust inserted Loss to the fiber optic link.  Our fiber attenuator series include: SC , FC, LC, ST, MU, SC/APC, FC/APC, single mode fiber optic attenuator and multimode fiber optic attenuator available. 
Inline fiber optic attenuator are with more accurate attenuation compared with traditional connector type fiber optic attenuators.
