Optical fiber connector core components ceramic ferrules will achieve localization
 
The ceramic ferrule, which is a white column fitting with a length of 2 cm and the thickness of a ballpoint pen tube, is the most delicate core component of the fiber optic connector. A fiber optic connector requires two ceramic ferrules, the purchase price is 2 to 3 yuan each, and the production itself, the cost can be reduced by 50% to 60%. However, the manufacturing technology of this product has been monopolized by Japanese companies.
 
At present, the rise of the mobile Internet and the dramatic increase in the broadband network speed are imperative, and the global optical fiber market is booming. The Hebei Sifang Communication Parent Company decided to take the global optical fiber industry development express train, starting from the solution of "China Core", launched the international monopoly and domestic blank ceramic ferrule project.
