MEISU's industry-leading pm fiber assemblies are designed for high-performance interferometric sensors, integrated optics and communications. All the rich experience and know-how in ultra-precise assembles enable us to offer PM fiber array sub-assemblies and other optical devices for different areas like optical communication, biological/chemical sensing, and laser imaging.
MEISU's polarization maintaining optical fiber array is a row of PM fiber of any specified orientation (error< 3 degree). The most common orientation of this polarization maintaining fiber alignment is slow axis horizontal, vertical or 45 degree tilted. PM FAU is normally used in coherent communication and fiber sensoring system.

How It Works
Polarization maintaining fiber pdf or the so-called pm fiber array and PMF fiber, can normally ensure the direction of linear polarization and effectively improve the coherent signal-to-noise ratio. Capable of realizing the high-precision measurement of physical quantity, polarization maintaining fiber is widely used in interferometric fiber optic sensor, which is theoretically based on optical coherent detection, fiber optic gyro and fiber optic hydrophone. Thus, in order to expand the use of polarization maintaining single mode fiber and increase the dosage of products, it is better to integrate PM fiber into fiber array.
