Collimator Variable Optical Attenuator
OPTICO's single-mode variable optical attenuators allow the user to manually change the attenuation of the signal in the fiber as it travels through the device. These VOAs can be used to precisely balance signal strength in fiber optic circuits or to balance optical signals when evaluating the dynamic range of a measurement system. The maximum specified attenuation is achieved within 10 turns of the adjusting screw. See Decay Data Tab for more information.
