Network Attenuator
DiCon’s Network Attenuator is a stepper motor-based compo-
nent 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 con-
nects.
