Background
The submarine cable is an optical cable laid on the seabed, and optical fibers are wrapped in the submarine cable for realizing transmission of optical signals between different islands or across the ocean. Due to the long submarine communication distances, it is often necessary to interface a large number of submarine cables in sequence, or to interface submarine cables in sequence with other intermediate equipment (e.g., repeaters, splitters, etc.), to form long-distance optical signal transmission paths.
The sea cable is usually stored in a winding and curling manner, but the intermediate equipment is of a rigid structure, so that the curvature of the joint of the intermediate equipment and the sea cable is smaller, namely the winding and curling are stored, and the bending of the joint is more obvious. And the connection that the camber is less, the condition that the submarine cable excessively bends appears easily, and the submarine cable of excessively bending can direct influence the transmission quality of optical signal in the submarine cable inside.
In order to solve the problem that the connection between a submarine cable and intermediate equipment is excessively bent to cause poor optical signal transmission quality, in the prior art, a rubber sheath is generally arranged at the tail end of the intermediate equipment in a buckling or bonding mode to protect a tail fiber at the tail end of the intermediate equipment, so that the intermediate equipment is protected as protected equipment, but the existing sheath is generally simple thin-wall rubber and has poor performance, the thin-wall rubber is still easy to bend, the submarine cable is excessively bent, and the rubber sheath is flexibly connected with a metal structure in a buckling or bonding mode, so that the connection is easy to loosen and has low protectiveness.
