SC fiber attenuators are used to reduce the power level of an optical signal of a fiber optic cable by up to 30dB. A fiber attenuator is commonly used in fiber-optic communications to the power level of a fiber cable by controlling the amount of signal loss that is passed through the signal. Fiber optic attenuators can also be used on a more permanent basis in order to match the signal with a transmitter and receiver's specific power levels.
