40/50µm Diameter Operating at 1310nm/1550nm Extremely fine PANDA-type pm fiber

The ultra-fine diameter Panda-type polarization-maintaining fiber used for fiber optic gyroscope winding is mainly aimed at the high precision, miniaturization and low cost requirements of fiber optic gyroscopes. We have developed an ultra-fine diameter Panda-type polarization-maintaining fiber with an outer diameter of 80 microns to meet the winding requirements of various small-sized rings. In particular, the 50/80 size series polarization-maintaining fiber is compatible with the current mainstream fusion splicing equipment and can be normally connected with 60/100 waveguide fibers.
