摘　　要：应用于高精度光纤陀螺的细径熊猫型光纤属于应力致偏型保偏光纤(PMF)。对工作波长为1 550nm的细径PMF的特性与研制过程进行了详细的阐述。所制备出的拍长为3.2 mm、消光比为26 dB(1 km)、低衰减、高强度且温度特性稳定的实用型细径熊猫型PMF为开拓国内高精度光纤陀螺及相关的光纤传感器件的工程化应用奠定了重要的基础。The reduced diameter PANDA type PMF used for high precision gyro belongs to stress-induced PMF. The characteristics and development process of the reduced diameter PMF which is operated at 1 550 nm are described in detail. The fabricated fiber offers 3.2 mm of beat length, 26 dB（1 km） of extinction ratio, and the features of low attenuation, high strength, and stable temperature characteristic. It is a PANDA type PMF suitable for practical use and establishes a firm foundation for the engineering application of high precision gyro and associated fiber optic sensors in China.
