FOG PM Panda Fiber
Description
We have complete equipment technology and process technology for polarization maintaining fiber, including PCVD equipment, drilling equipment, wire drawing equipment, and testing equipment with independent intellectual property rights. The polarization-maintaining optical fiber is made of invention patented technology, and has a complete set of proprietary technology for drilling the polarization-maintaining core rod, boron stress rod, and mother rod at one time.
Our polarization-maintaining fiber products for gyroscopes are special fibers designed for fiber optic gyroscopes (FOGs). They adopt a panda structure (Panda), which contains a perfect and symmetrical "panda eye" stress unit. The core and the center of the panda eye are in a straight line at three points. This design provides high reliability for high polarization crosstalk.
