Fiber optic attenuator, also named optical attenuator, is a small device developed to reduce the power level of an optical signal. The receiver may be damaged When the optic signal arriving at the receiver is too strong. The attenuator can be used to avoid it to happen.
This fiber optic LC attenuator is a fixed value male to female attenuator. The attenuation value can be 1~30db. It is widely used on SFP receivers.
