The fully programmable IQ-3100 Variable Attenuator offers reliable and repeatable performance and is ideal for automated BER testing.

Optical system manufacturers know that variable attenuators are essential in order to keep their test systems running smoothly. They look for performance, user-friendliness, complete control of test parameters and advanced programming capability. EXFO’s IQ-3100 Variable Attenuator combines innovative design techniques, high-quality components and meticulous calibration procedure. Reliability and repeatable performance. That’s what the IQ-3100 offers, in 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. Add a user-friendly Windows environment, and you’ve got a first-class variable attenuator.
