980/1064nm Polarization Maintaining Filter WDM
The 980/1064nm Polarization Maintaining Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate 980nm and 1064nm optical signals while maintaining the polarization state in PM fiber systems. It provides low insertion loss, high channel isolation, high extinction ratio, and stable optical performance in a compact package. With PM980 fiber support and both-axis operation, this PM Filter WDM is suitable for PM fiber laser systems, pump laser coupling, fiber sensing, interferometric systems, optical test equipment, and other polarization-sensitive applications requiring reliable wavelength combining or splitting between 980nm and 1064nm channels.
