It uses one or more optical fibers as the transmission medium. The basic structure of the optical cable is composed of cable core, reinforcing steel wire, filler and sheath. Ribbon optical cable is an installation-related technical standard. Multiple optical fibers are pasted and arranged in a specified manner to form one or more groups of ribbon-shaped optical cables. Such optical cables are called ribbon optical cables.

[0004] The inventors have discovered in their daily work that in the process of using micro-ribbon optical cables as transmission media, there is a problem that existing ribbon optical fibers, such as the above-mentioned ones, use fiber reinforcements to strengthen the structural strength of both sides of the optical fiber. Since the two sides of the entire optical fiber have a large area, when only fiber reinforcements are used for reinforcement, the reinforcement range is limited, and the structural strength of the optical fiber end face is not uniform, thereby reducing the compressive performance of the end face.

By installing the end sleeve on the free end of the protective layer, the outer protective layer and the inner protective layer installed on the protective layer can be blocked, thereby ensuring that the outer protective layer and the inner protective layer are on the protective layer.

[0009] Preferably, the buckle frame is stepped, and the end of the buckle frame away from the end sleeve is hook-shaped, and the inner wall of the hook of the buckle frame is adapted to the connecting column. By buckling the elastic buckle frame onto the connecting column, the buckle frame can cooperate with the connecting column to tighten the outer protective layer and the inner protective layer.

The rubber gasket can replace the threaded rod in contact with the protective layer, thereby reducing the problem of direct contact of the threaded rod with the protective layer, which may easily cause damage to the protective layer.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, by setting the protective components and the auxiliary components, after the production of the optical cable is completed, the outer protective sleeve and the inner protective sleeve are aligned with the arc surface on both sides of the optical cable, and the outer protective sleeve and the inner protective sleeve are pushed to make them cover the surface of the optical cable. After the outer protective sleeve and the inner protective sleeve completely protect the optical cable, the end sleeves are covered on the free ends of both sides of the optical cable. In the process of installing the end sleeves, the buckle frame is gradually clamped on the connecting column. When the end sleeves are completely covered on the surface of the optical cable, the knobs on both sides of the end sleeves are rotated respectively, and the knobs drive the threaded rod to rotate. The threaded rod gradually rotates the knobs and pushes the rubber gasket When the threaded rods on both sides are fully tightened, the rubber gaskets on both sides are tightly against the surface of the protective layer, and cooperate with the threaded rods and the threaded sleeves to clamp the protective layer to fix the end sleeve, and then the installation operation of the protective component is completed.
