The Ando AQ8202-422 is a dual optical switch module that routes optical signals across a 2×2 switching configuration within the Ando AQ8200 Series Optical Test and Measurement System. Equipped with two independent optical switches and FC/APC connectors, this module handles single-mode fiber (9/125 µm) signals across the C and L bands. It delivers low insertion loss, high isolation, and minimal polarization-dependent loss for precise optical path switching in telecom and component characterization applications.
