1064/1550nm Polarization Maintaining Filter WDM
The 1064/1550nm Polarization Maintaining Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate 1064nm and 1550nm 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 and PM1550 fiber support and both-axis operation, this PM Filter WDM is suitable for PM fiber laser systems, polarization-sensitive optical communication, fiber sensing, interferometric systems, optical test equipment, and applications requiring reliable wavelength combining or splitting with polarization-maintaining performance.
