Panda PMF for FOG Winding
Panda PMF series products manufactured by YOEC can be used in the field of fiber optic gyroscope and other polarization-related devices. It has the characteristics of excellent attenuation, polarization-maintaining performance, temperature stability & reliability, which can meet various requirements for application.
YOEC uses chemical vapor deposition process to manufacture Panda polarization-maintaining fiber with the advantages such as good geometric symmetry, good axial uniformity and etc..
1. Introduction
Panda polarization-maintaining fibers for FOG winding manufactured by YOEC are mainly used in the fiber coil of fiber optic gyroscope. In view of its application environment, the mechanical reliability, temperature stability and environmental adaptability of the fibers are improved, the axial uniformity and batch consistency of the fibers are optimized, and the inner & outer coatings of the fibers are coated with self-developed coating materials, which have good full-temperature stability, environmental adaptability and mechanical reliability. It can be used in the temperature range of -50ºC to +105ºC.
