提出了一种基于电缆内埋光纤的海底电缆状态监测新技术。它表明，分布式光纤振动传感器可以用来映射动态应变的所有沿着电缆同时。实验结果表明，该系统可以完全量化的位置和应变水平在每个点上的电缆作为时间的函数的突然冲击和循环加载。该传感系统在10公里的传感范围内，空间和应变分辨率分别为1米和4 μ m。
A novel subsea cable condition monitoring technique based on embedded optical fiber inside the cable is demonstrated. It is shown that a distributed optical fiber vibration sensor can be used to map dynamic strains all along the cable simultaneously. It is experimentally shown that such system can fully quantify the location and strain level at each point on the cable as a function of time for both abrupt impact and cyclical loading. The sensing system demonstrated a spatial and strain resolution of 1 m and 4 mu epsilon, respectively, over a 10-km sensing range.
