Polarization Maintaining Optical Fiber Array
MEISU's polarization maintaining optical fiberarray is a row of PM fiberof any specified orientation (error< 3 degree). The most common orientation of this polarization maintaining fiber alignmentis 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, or the so-called pm fiber array unitand 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, PMF fiber is widely used in interferometric fiber optic sensor, which is theoretically based on optical coherent detection, fiber optic gyro and fiber optic hydro. Thus, in order to expand the use of poly-maintaining fiber and increase the dosage of products, it is better to integrate PM fiber into fiber array alignment.
