Fiber Bragg Grating

Fiber Bragg Grating (Fiber Bragg Grating) :

FBG is a kind of technology that "selectively" reflects the signals of different wavelengths in the "core" of optical fiber according to a certain "proportion".

Industry pain points: the volume of products and top quality products are still blank in China; Major domestic research institutions have developed fiber Bragg gratings to form corresponding solutions for research topics in certain fields. But at present they do not have the ability of industrialization;

FBG products can be called "chips" in the field of optics. Up to now, the top technology of FBG products has always been monopolized by foreign countries. The United States has banned exports to China for decades
