The module includes a multi-core optical fiber and a single-core optical fiber bundle. The single-core optical fiber bundle includes multiple single-core optical fibers squeezed and bundled together. The number of single-core optical fibers in the single-core optical fiber bundle is the same as the number of cores of the multi-core optical fiber, and the arrangement position of the single-core optical fibers at the end face of the single-core optical fiber bundle corresponds to the arrangement position of the cores at the end face of the multi-core optical fiber. The end face of the single-core optical fiber bundle is docked and fixed to the multi-core optical fiber at the end face, and the single-core optical fibers of the single-core optical fiber bundle are connected one-to-one with the cores of the multi-core optical fiber.

[0003] The number and arrangement of the optical fibers in a single-core optical fiber bundle strictly correspond to those in a multi-core optical fiber, but inaccurate docking may occur during the actual manufacturing process. Utility Model Content

The structure includes a single-fiber capillary, a base, and a cover plate. The single-fiber capillary is penetrated by an MCF optical fiber along the front-to-back direction. The top surface of the base is provided with a positioning groove, through which an optical fiber array is penetrated. The optical fiber array is arranged along the front-to-back direction, and the front end of the optical fiber array is coupled to the rear end of the MCF optical fiber. The cover plate covers the top surface of the base and is located above the positioning groove.

[0007] Optionally, the positioning groove is a V-shaped groove.

[0008] Optionally, the positioning groove is in the shape of an isosceles triangle.

[0009] Optionally, the top surface of the base is stepped, and the front side of the top surface of the base is higher than the rear side.

[0012] Optionally, the single-fiber capillary is provided with a through channel for the MCF optical fiber to pass through.

[0013] Optionally, the through-channel has a cylindrical structure.

[0014] The beneficial effects achieved by the utility model are:

[0015] 1. The structural design of the single-fiber capillary, base, and cover ensures precise docking between the fiber array and the MCF fiber end face, solving the possible problem of inaccurate docking.

[0016] 2. The positioning groove and optical fiber array provide a simpler and more efficient optical fiber connection, simplifying the assembly and operation steps;

[0017] 3. Due to the presence of the positioning groove, the present application improves the stability of optical fiber docking, ensures a more solid and stable connection between the optical fiber array and the MCF optical fiber, and avoids optical signal loss caused by unstable connection;
