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.

Kocent Optec Limited can supply all attenuation grade of fiber optic attenuator such as 1dB, 2dB, 3dB, 5dB, 7dB, 10dB, 15dB, 20dB, 25dB, etc. The fiber optic attenuator can be in fix type or adjustment type. For fix type, we can supply adapter type and male convert into female type. For adjustment type, we can supply in female to female type and online type. Adjustment type fiber optic attenuator can be adjust any attnuation grade as you need.
