CDL公司根据一些规范的要求研制了一种光缆结构,它是将高性能的光纤松弛地置于一根塑料棒的槽内,而塑料棒则位于高强度光缆的中央。深海光缆是铠装光缆或登陆光缆的基本结构。加铠装的过渡段设计得能减小光缆的扭绞。耦合部的设计使光缆和中继器之间保持良好的光电和机械连续性。所设计的深海维修技术可在光缆船上进行。光缆、维修技术和耦合技术已经成功地经受了好几次海洋试验,二条实验线路现正在运行。在使用了19个月的第一条线路上没有观察到光缆中光纤的衰减有什么增加。S280光缆的研制工作正照此正确路线进行。
CDL has developed a fiber optic cable structure based on a number of specifications that loosely place high-performance fibers in the grooves of a plastic rod while the plastic rod is centered in a high-strength fiber optic cable. Deep sea cable is the basic structure of armored cable or optical cable. Plus armored transitional section designed to reduce the cable twist. The design of the coupling maintains good optical and mechanical continuity between the optical cable and the repeater. The design of deep sea maintenance technology can be carried out in fiber optic boats. Cable, maintenance, and coupling technologies have successfully undergone several marine tests and two experimental circuits are in operation. No increase in attenuation of the optical fiber in the optical cable was observed on the first line of 19 months. Development of S280 cable is taking the correct route.
