The Horizontal Type Splice Closure is a mechanical pressure seal joint system, which is a joint protection device that provides optical, sealing and mechanical strength continuity between adjacent cables. It is mainly used for straight-through and branch connection of overhead, pipeline, direct burial and other laying methods applicable to various structural optical cables. The box body is made of reinforced plastic, high strength and corrosion resistance. The splice closure is suitable for connection in the terminal room of the structural fiber optic cable. The structure is mature, the seal is reliable, and the construction is convenient. Widely used in communications, network systems, CATV cable TV, fiber optic cable network systems, and more.
