COTDR技术在海光缆监测中的应用

Application of COTDR Technology in Submarine Cable Monitoring

由于海光缆铺设在复杂恶劣的海洋环境中,容易受到环境因素的破坏,传统的OTDR技术已经无法满足监测需求,而COTDR技术正好能弥补不足。在介绍COTDR技术的原理和海光缆监测技术发展现状基础上,研究了COTDR对应力的检测方法,并对COTDR在海光缆监测和维护中的应用进行了探讨。

Because the submarine cable laying in the complex and harsh marine environment,easy to be damaged by environ- mental factors, the traditional OTDR technology can not meet the monitoring requirements, and the cotdr technology can make up for deficiencies. Based on the introduction of the principle of cotdr technology and the development status of sea optical fiber monitoring technology, the detection method of cotdr for stress is studied, and the application of cotdr in monitoring and main-tenance of sea optical cable is discussed.
