Miniature Variable AttenuatorAttenuators
Units: mm
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 tur ning 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 boar d or
within an enclosure.
Features
•Wide attenuation range
•Precise r esolution
•Low back reflection
•Low insertion loss
•Low polarization dependent loss
Applications
Miniature Variable Attenuators can be used to adjust optical power
levels in factory test and field transmission systems. Applications
include optimizing receiver sensitivity in optical networks.
