Deep sea optic cable and its manufacture method

Abstract

The invention provides a deep sea optical cable and producing method thereof, relating to a deep sea optical cable with a tension-resistant compact composite structure and producing method thereof. The structure of the deep sea optical cable comprises a plurality of full chromatogram high-strength optical fibres, high-strength anti-corrosion stainless steel tubes, ointment exclusive for sea cable optical fibre, special-high-strength armouring wires with three diversified diameters, a heavy viscous waterproof agent, metallic conductor brass pipes, organic plastic composite materials, and a polythene insulation material protective layer. High-strength anti-corrosion stainless steel tubes are sleeved on several full chromatogram high-strength optical fibres, ointment exclusive for sea cable optical fibre is filled into the high-strength anti-corrosion stainless steel tubes, special-high-strength armouring wires with three diversified diameters are inlaid on the outside of the high-strength anti-corrosion stainless steel tubes and are filled with heavy viscous waterproof agent of sufficient amount, the special-high-strength armouring wires are covered with the metallic conductor brass pipes, so that special tension-resistant compact composite structure is formed. Organic plastic composite materials are added on metallic conductor brass pipes, and then an insulation material protective layer is extruded thereon.

Description

technical field [0001] The deep-sea optical cable and its manufacturing method of the present invention relate to a deep-sea optical cable with a tensile compact combined structure and its manufacturing method, which is a kind of high-strength steel wire armoring of three different specifications with a stainless steel optical fiber unit and special tooling equipment. , and then the metal tube is covered and locked. The outer layer is protected by insulating materials with excellent electrical properties. The gaps between the steel wires and the gaps between the steel wires and metal conductors are all sealed with high-viscosity elastic materials. This kind of structure submarine optical cable is suitable for the sea state with the maximum water depth of 5000 meters and the optical communication system under the water pressure of 5000 meters. Background technique [0002] At present, the international deep-sea optical cable technology has completed structural verification an...
