Ferrule and optical fiber connector used for optical fiber butt joint and method for achieving optical fiber butt joint

Abstract

The invention provides a ferrule and an optical fiber connector used for an optical fiber butt joint and a method for achieving the optical fiber butt joint. A though hole is arranged in the ferrule, an optical fiber is inserted into one side of the through hole or an embedded optical fiber is distributed in the one side of the through hole, an optical fiber is inserted into the other side of the through hole, so that the optical fibers on the two sides are in the butt joint at the preset butt joint position of the through hole, the side wall of the ferrule, which corresponds to the preset butt joint position, is provided with an exhaust passage, and then the through hole is communicated with outside. The ferrule is utilized in the optical fiber connector and the method for achieving the optical fiber butt joint. According to the ferrule and the optical fiber connector used for the optical fiber butt joint and the method for achieving the optical fiber butt joint, the optical fibers are in the butt joint in the through hole of the same ferrule, the accuracy of the diameters of the through hole and the optical fibers is high, the diameter of the through hole is excellently matched with the diameter of the optical fibers, thereby the accuracy of the optical fiber butt joint is improved, the structure is simple, the production processing is convenient, long-term and reliable operation after the butt joint can be guaranteed, due to the fact that the exhaust passage is arranged at the position of the optical fiber butt joint point, bubbles generated during the optical fiber butt joint process are eliminated, and the butt joint reliability is improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber connection, in particular to a sleeve for optical fiber connection, an optical fiber connector and a method for realizing optical fiber connection. Background technique [0002] In the construction site of optical fiber communication, especially in the construction process of optical fiber to the home, it is necessary to realize fast and reliable connection of optical fiber. The welding method can achieve reliable connection, but requires special equipment and has high requirements on the operation process. Some existing connection methods need to grind the end face of the optical fiber and assemble it into a specific connector, which is not suitable for installation on the construction site. Although some existing fast connection methods can directly connect the cut optical fibers, the connection is not stable enough due to some defects in the technical solution, and there are problems in ...

AI Technical Summary

Problems solved by technology

[0005] 1. The part of the optical fiber protruding from the ceramic sleeve is easy to break during the assembly process, which affects production efficiency and yield;

[0006] 2. The precision of the V-groove is not high, and it is difficult to ensure high docking accuracy when the optical fiber is docked in the V-groove; the opening on the top of the V-groove needs to be pressed tightly by the cover plate, and the compression of the cover plate is difficult to ensure the accuracy of the fiber docking;

[0007] 3. Since the pre-embedded optical fiber and the inserted optical fiber are respectively clamped in the ceramic sleeve and V-groove, the difference in thermal expansion coefficient of different materials will also affect the reliability of the optical fiber docking in different environments, and the reliability of various materials after long-term use Aging will also lead to poor docking effect and shorter service life
