摘要
随着光纤传输的高速发展,对光缆线路的维护和管理要求越来越高。特别是在发生光纤故障时,会产生较强的噪声干扰。如何能够准确、快速地进行故障定位,成为保证通信网络畅通运行的关键问题。针对这一问题,提出一种基于通信光缆OTDR信号去噪的新方法。最后通过仿真实验证实,此方法可有效去除OTDR光缆信号中的强噪声,实现光缆断点的准确定位。
With the rapid development of optical fiber transmission,the maintenance and management requirements of the optical fiber are more and more high.Especially in cases of optical fiber fault,will have the strong noise interference.How to accurately,quickly find out breakpoint,become the key problem of smooth communication.To solve this problem a method based on denoising optical cable OTER signal is put forward.Finally through the simulation experiments verify that this method can effectively remove the OTDR optical signal in strong noise,realizing of the optical cable breakpoint positioning accuracy.
