The Exfo IQ-3100-BWEI is a variable attenuator module engineered for precise optical power control within IQ-2000 and IQ-3000 series test platforms. It delivers sub-dB resolution and exceptional repeatability across a broad wavelength range, enabling accurate receiver sensitivity testing, dynamic range verification, and optical margin analysis. The module supports multiple attenuation modes and programmable step sequences, with remote control via GPIB and LabVIEW drivers.
