Fiber optic attenuator is a device 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.

Fixed optical attenuators used in fiber optic systems may use a variety of principles for their functioning. Preferred attenuators use either doped fibers, or mis-aligned splices, since both of these are reliable and inexpensive.

Inline style attenuators are incorporated into patch cables. The alternative build out style attenuator is a small male-female adapter that can be added on to other cables.

The fiber optic attenuators can be used on a more permanent basis in order to match the signal with a transmitter and receiver's specific power levels. Commonly used attenuation range is from 1dB to 30dB.

MPO Attenuator is used to reduce optical-signal electric power in all channels of 40/100G Parallel Optic Transmission, and other equipment with using MPO interconnection.

Technique of this product makes network's composition more concise than those of conservative way which is the connection method of attenuator independently in each channel, as downsizing the volume and saving time.

This MPO Attenuator meets TIA/EIA 604-5. And IEC 61754-7 with compliance for RoHS.
