The embodiment of the invention discloses an
optical fiber butting device, including a butting matrix
barrel and a plurality of line butting devices located in a butting matrix
barrel cavity and fixedly connected with the butting matrix
barrel, one line butting device is fixes an external
optical fiber, during specific working, only the line butting devices need to be utilized to fix external optical fibers, the external optical fibers are inserted in butting holes of the butting matrix barrel, then the
tail fibers or two cord circuit butting pieces connected by the
tail fibers are utilized to be inserted in the butting holes into which two external optical fibers to be butted are inserted, thus automatic butting of the two external optical fibers can be realized, the operation is simple, manual participation can be greatly reduced, and plenty of manpower and
material resources are saved. In addition, in the
optical fiber butting device provided by the embodiment of the invention, the butting matrix barrel is of a hollow columnar structure, and the butting holes are arranged on the side wall of the butting matrix barrel, and thus on the premise of the same number of butting holes, the horizontal occupation area of an optical
fiber core butting matrix structure is greatly reduced.
