The Exfo IQ-3100-C54 Variable Attenuator 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-C54 maintains an attenuation value within ± 0.1 dB throughout the complete WDM spectrum, simultaneously. 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. Specifications. Fiber type: 50/125 µm. Wavelength range: 700 to 1350 nm. Wavelength resolution: 0.1 nm. Max. attenuation: >= 100 dB (700 nm to 1000 nm), >= 65 dB (1000 nm to 1350 nm).
