Ando AQ8201-21 Optical Power Meter Module

The Ando AQ8201-21 is a high-sensitivity optical power meter module designed for accurate, real-time measurement of optical power in fiber optic networks. Built around a cooled InGaAs detector, it integrates into Ando AQ8201 Series mainframes as a single-slot module, enabling deployment across laboratory characterization, component testing, and telecommunications network maintenance workflows.
