SC single mode fiber attenuators are commonly used in fiber optic communications to the the power level of a fiber cable by controlling the amount of signal loss that is passed through the signal. Commonly used attenuation range is from 1dB to 20dB.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, fiber optic attenuator name is based on the connector type and the attenuation level. SC Build Out Fiber Attenuators include SC/UPC fiber attenuators and SC/APC Female to Male Fiber Attenuators.
