The JW8606 dual-channel polarization extinction ratio tester is a new-generation precision optical testing instrument developed by Jiahui Company, dedicated to the polarization characteristic testing of polarization-maintaining devices and light sources. Its core functions include polarization extinction ratio testing of polarization-maintaining fibers, polarization-maintaining optical devices, and polarization-maintaining connectors, as well as measurement of the degree of polarization and polarization axis angle of light sources. It also supports measurement of the additional loss and splitting ratio of Y-waveguides. The instrument is also equipped with powerful, user-friendly host computer software, integrating multi-purpose, high-precision, and ease of operation, and can effectively improve testing efficiency.
