The most commonly used type is female to male plug type fiber optic attenuator. It has the optical fiber connector at one side and the other side is a female type fiber optic adapter,Website:://.zgtech-solution.com, fiber optic attenuator name is based on the connector type and the attenuation level. ST 5dB fiber optic attenuator means this attenuator use ST fiber optic connector, and it can reduce the optical fiber power level by 5dB. Commonly used attenuation range is from 1dB to 25dBSize Information:
