Polarization-maintaining optical fiber transmission line polarized light, widely used in aerospace, aviation, navigation, industrial manufacturing technology and communications and other areas of the national economy.In the interferometric fiber sensor based on optical coherence detection, the use of polarization-maintaining fiber can ensure the linear polarization direction unchanged and improve the coherent signal-to-noise ratio, so as to realize the high-precision measurement of physical quantities. Polarization-maintaining fiber as a kind of special fiber, is mainly used in fiber optic gyro, fiber optic hydrophone and other sensors and DWDM, EDFA and other fiber optic communication systems.
