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.
Features
•Low polarization dependent loss and wavelength flatness over
the entire attenuation range
•Standard model features ultra-linear response function
•Customer-specified attenuation range and response function
•Optional input and output monitors
Applications
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.
