Attenuators Specifications1 Miniature Variable Attenuator Attenuators Optical Performance Miniature Variable Attenuator DiCon's Miniature Variable Attenuator is a fiber pigtailed component which is used to set attenuation levels in the range of 0 to 50 dB. By turning a high precision adjustment screw, attenuation can be set to within 0.1 dB. The compact housing is designed for mounting on a printed circuit board or within an enclosure.
