AI Technical Summary
The existing ceramic ferrule structure results in insufficient tensile strength of optical fibers, especially in straight-pull and lateral-pull performance.
The design includes a first straight hole section, a second straight hole section, and a third straight hole section that are sequentially connected along the axial direction and have progressively smaller inner diameters. The third straight hole section is fitted with the fiber cladding with a minimum clearance. The inner diameter of the second straight hole section is increased to increase the amount of adhesive. The first straight hole section is used for the insertion of the fiber coating layer to increase the bonding area. The transition section is designed to ensure the concentricity of the fiber and the uniform distribution of the adhesive.
It significantly improves the resistance to direct and lateral tension of optical fibers, enhances the connection strength between the optical fiber and the ferrule body, and reduces the fiber breakage rate.
