The Exfo IQ-3100 Variable Attenuator series is a flexible and fully programmable module. Choose from three attenuation modes: absolute, relative and X+B. Cycle through a repeatable sequence of up to 100 attenuation steps, with a dwell time of up to 1000 hours per step. The IQ-3100 maintains an attenuation value within ± 0.1 dB throughout the complete WDM spectrum, simultaneously for all channels from 1520 nm to 1570 nm. Attenuation from minimum insertion loss (typically 1.5 dB) to 100 dB according to operating wavelength and recurring attenuation (± 0.03 dB) each time you select a specific setting at a specific wavelength. Single mode models have a wavelength range of 1200 to 1650 nm, multimode models have a wavelength range of 700 to 1350 nm. Max. attenuation is 100 dB.
