Because of the miniaturized trend of fiber optic gyros, it is necessary to wind fiber coils through smaller diameter Panda PM fibers. In order to meet the needs of customers, the small diameter PMF is designed and manufactured through thin coating technology which decreases the PMF diameter from 165μm to 135μm, and delivers outstanding performance in compact gyros. The performance of small diameter Panda PM fiber can be guaranteed, such as high birefringence, low attenuation, crosstalk stability, precise refractive index profiles, good geometric symmetry and longitudinal uniformity.
