Other Attenuators

Network Attenuator

DiCon’s Network Attenuator is a stepper motor-based component which is used to adjust power levels in DWDM network transmission systems. It features a novel shutter design, which can be customized to provide any arbitrary relationship between insertion loss and control voltage.


Network Attenuators are used to adjust gain tilt in erbium-doped fiber amplifiers. Network attenuators can also be used for signal pre-emphasis of WDM lasers in long haul systems as well as power equalization in optical add/drop multiplexers and optical cross connects.
