1310/1550nm Polarization Maintaining Filter WDM
The 1310/1550nm Polarization Maintaining Filter WDM is a thin film filter-based wavelength division multiplexer designed to combine or separate 1310nm 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 PM1300 and PM1550 fiber support and both-axis operation, this PM Filter WDM is suitable for polarization-sensitive optical communication, PM fiber amplifiers, fiber laser systems, fiber sensing, interferometric systems, and laboratory test applications requiring reliable wavelength combining or splitting with polarization-maintaining performance.
