保偏光纤作为一种特种光纤,主要应用于光纤陀螺,光纤水听器等传感器和 DWDM,EDFA 等光纤通信系统。由于光纤陀螺及光纤水听器等可用于军用惯导和声呐,属于高新科技产品,而保偏光纤又是其核心部件,因而保偏光纤一直被西方发达国家列入对我禁运的清单。
As a kind of special fiber, polarization maintaining fiber is mainly used in fiber optic gyroscope, optical fiber hydrophone and other sensors and DWDM, EDFA and other optical fiber communication systems. As fiber optic gyroscopes and fiber hydrophone can be used for military inertial navigation and sonar, high-tech products, and polarization-maintaining fiber is its core components, so polarization-maintaining fiber has been included in the western developed countries list of the embargo against me.
