Speciality PM Fiber for Gyro

      The polarization maintaining optical fiber of type 'I' has an excellent structure with independent innovation, absorbing the double advantages of bow-tie type and elliptical jacket type, and creating a unique structure of small stress area at home and abroad, whose area of stress area is only 1/3~1/4 of that of the Panda type, which can achieve the same or even better polarization maintaining effect. It bring great improvement to the temperature performance, bending resistance and strength performance of polarization maintaining optical fiber.

     This fiber has been successfully applied to the navigation, positioning and attitude control systems of various platforms in sea, land, air and space.
