The JW18001 PER multi-channel polarization extinction ratio test system is a high-precision test platform developed by Jiahui Optics based on years of experience. It is dedicated to the core performance evaluation of polarization-maintaining devices and systems, and can accurately perform polarization extinction ratio (PER) measurement, light source degree of polarization analysis, and extinction ratio testing of polarization-maintaining fibers and connectors. The system has large dynamic range PER measurement capability, supports multi-channel synchronous detection and channel expansion, and while achieving high-precision, high-stability testing, integrates insertion loss measurement, temperature monitoring, and continuous data recording functions. Its host computer software facilitates data management and statistical analysis and supports long-term reliability monitoring, making it an ideal test solution for ensuring efficiency and reliability of polarization-maintaining devices in R&D, production, and quality inspection.
