Fiber optic attenuators are devices which reduce (attenuate) the strength of a fiber optic signal within a fiber optic network. Attenuators are usually used when the signal arriving at the receiver is too strong and hence may overpower the receiving elements. Sometimes attenuators are also used for stress testing a network link by incrementally reducing the signal strength (increasing the dB attenuation) until the optical link fails, thus determining the signal's existing safety margin.

Our singlemode attenuators offer a operating wavelength range of 1250nm to 1600nm.Three types (male-female type, fixed type, in-line type) attenuators can be supplied to our client.
