Fiber Optic In-line Attenuator

Product description
In-Line Attenuator
In-Line Fixed Attenuators convert optical power into heat and the power is then attenuated inside the devices and
dampens the fiber optic signal. Attenuation is needed when an optical signal has too much power and exceeds the
operating range of the equipment.
