Description of the invention: 'Technical field to which the invention pertains>> The present invention relates to a fiber coupling process, and more particularly to a fiber coupling process having a high optical coupling efficiency. [Prior Art] In the optical fiber communication system, optical power loss is inevitably generated in the process of laser-to-fiber, fiber-to-fiber, and optical-to-photodetector optical I. f, the laser beam provided by the laser diode is a beam with an elliptical cross section, but the cross-sectional shape of the fiber is circular, so in the process of coupling the fiber with the laser diode, it must be due to the mode of the light field. Mismatch, so that the laser beam can not fully enter the fiber, resulting in reduced light efficiency. Conventional techniques perform various processing procedures on optical fibers in an attempt to improve the efficiency of fiber bonding, such as grinding, sinter spinning, and laser micro-turning. The optical fiber is processed by the grinding method, which is difficult to manufacture, costly, and difficult to mass produce. The fiber is processed by the melt-spinning method, and the core of the fiber is thinned during the drawing process, which makes the geometric shape difficult to control and increases the coupling difficulty. The optical fiber is processed by the laser micro-turning method, and the pulsed laser equipment is expensive and the output is low, which does not meet the requirements of actual mass production. SUMMARY OF THE INVENTION The present invention is directed to an optical fiber processing process for solving the problems of the prior art, including the following steps. First, a bare fiber is provided, the bare fiber including a first segment and a second segment. Next, a surface of the first segment of the bare fiber is coated with a protective structure, wherein the protective structure is formed on the first segment by molding. Finally,
