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. 1525.0nm to 1575.0 nm Attenuation range > 30 dB Monitor Attenuation resolution < 0.1 dB I N Monotonicity > 0 dB/step Minimum insertion loss2 PMD 20 to 30 dB attenuation 0.30 dB max. 0.10 ps max.
