Fiber optic attenuator or optical attenuator is a passive component used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. However, the optical attenuator classified as fixed or variable attenuators. What’s more, they can be classified as LC, SC, ST, FC, MU, E2000, etc. according to the different types of connectors.
FOS provides optical attenuators with various connector types, such as LC/FC/SC/ST/MU/E2000, available with UPC or APC polish, male or female interface. Our fixed fiber attenuators with attenuation range from 1 dB to 2r dB (step by 1 dB), while the variable optical attenuators (generally used as in-line attenuators) can be adjusted from 0 to 60 dB.
