Optical Attenuator (Adjustable Type)

Overview

Adjustable fiber optic attenuator, also called variable fiber optic attenuator, usually is inline type, the appearance likefiber optic patch cords; it is with an adjustable component in the middle of the device to change the attenuation level to a certain figure. There are also handheld variable fiber optic attenuators; they are used as test equipment, and we have the inline fiber optic attenuators.
