现阶段,随着时代的发展和科学技术的进步,光缆在人们的日常中发挥着越来越重要的作用。就光缆而言,安装过程和维护过程都是非常关键的,此时需要借助的一个重要工具就是光时域反射仪(OTDR)。该仪器的主要作用是:对光纤中的一些异常现象进行检测,从而协助相关人员及时发现光缆中潜在的风险,并及时对其进行清除。在本次研究中,笔者主要围绕OTDR展开了研究。首先介绍了OTDR的工作原理,接下来分析了使用OTDR时应该注意的一些问题。
At this stage, with the development of the times and the progress of science and technology, the optical cable plays an increasingly important role in people’s daily life. In the case of fiber optic cables, the installation process and the maintenance process are all critical, and an important tool to take advantage of is the Optical Time Domain Reflectometer (OTDR). The main function of this instrument is to detect some abnormal phenomena in the optical fiber to help relevant personnel find out the potential risks in the optical fiber cable in time and remove it in time. In this study, I mainly focus on OTDR research. First introduced the working principle of OTDR, followed by analysis of the use of OTDR should pay attention to some of the problems.
