PM 1550nm 2×2 Polarization Beam Combiner/Splitter

The PM1550-2×2 Polarization Beam Combiner/Splitter provides high-performance polarization management with low insertion loss, high extinction ratio, and excellent isolation. Operating at 1550 nm with a ±40 nm wavelength range, this 2×2 port component ensures reliable polarization beam combining and splitting while maintaining signal integrity through precise slow-axis operation and fast-axis cutoff.

Ideal for optical fiber gyros, coherent telecommunication systems, fiber optic testing, and research applications, the combiner/splitter offers stable performance across extended temperature ranges. Its robust design and flexible configuration options—including power handling up to 10 W, multiple fiber types, and various connector styles—enable seamless integration into a wide range of polarization-sensitive optical systems.
