How It Works
Polarization maintaining optical fiber, or the so-called pm fiber array alignment 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, PMF 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 poly-maintaining fiber and increase the dosage of products, it is better to integrate PM
fiber into fiber array.
