Underwater cable

Underwater optical cables are optical cables that radiate through the rivers, lakes, beaches and other places under the water. The laying of such optical cables is much more difficult than the laying of pipes. The submarine optical cable must adopt the structure of steel wire or steel tape armor. The structure of the protective layer should be comprehensively considered according to the hydrogeological conditions of the river. For example, in rocky soils, where seasonally eroding seasonal riverbeds are exposed, optical cables are subject to wear and tear, and in cases where the pull force is large, not only heavy steel wires are required to be skid-mounted, but also to use double-layered armoring. The method of construction must also be based on the width of the river. Water depth, flow rate, riverbed drawings, etc. are selected. The laying conditions of submarine optical fiber cables are much more severe than those of direct-buried optical cables, and the technology and measures for repairing faults are also much more difficult. Therefore, the reliability requirements for underwater optical cables are also higher than that of direct-buried optical cables.

The submarine cable is also a submarine cable, but the laying of environmental conditions is more severe than the average submarine cable, and the requirements are higher. The service life of the submarine cable system and its original parts is required to be more than 25 years.
