PM 1310nm 1×2 Polarization Beam Combiner/Splitter

The PM1310-1×2 Polarization Beam Combiner/Splitter provides high-performance polarization management with low insertion loss, high extinction ratio, and excellent isolation. Operating at 1310 nm with a ±40 nm wavelength range, this component ensures reliable polarization beam combining and splitting while maintaining signal integrity through precise slow-axis operation with fast-axis cutoff.

Ideal for optical fiber gyros, coherent telecommunication systems, fiber optic testing, and research applications, the combiner/splitter delivers stable performance across extended temperature ranges. Its compact design and flexible configuration options—including power handling up to 10 W, various fiber types (SM-28E or PM1300-XP), and multiple connector styles—enable seamless integration into diverse polarization-sensitive optical systems.
