Applications of BOTDR in the manufacturing processes of optical fiber cable
摘要
文章首先介绍了用 BOTDR测试光纤应变分布的原理
然后介绍了用 BOTDR测试、分析层绞式光缆的生产各工序过程所引入的光纤应变大小的一种方法
事实证明
这一方法对于分析光缆各生产工序的控制状态十分有效 .
Abstract
In this paper
we have introduced the principle of measuring the fiber strain with a BOTDR
and have introduced a test method with BOTDR to analyze the fiber strain distribution of each process in manufacturing stranded loose tube cable. It was proved by two examples that the method introduced below is very effective for the analyzing of manufacturing control process.
