The Yokogawa AQ2200-332 is a single-slot optical attenuator module for the AQ2200 Multi Application Test System. It delivers precise optical signal attenuation across a broad wavelength range while simultaneously monitoring output power through an integrated optical power meter. The module combines variable optical attenuation with real-time power measurement in a compact footprint, making it essential for bit error testing, optical attenuator evaluation, and photoreceptor characterization in laboratory and field environments.
