摘要
为有效实现通信光缆信号和噪声之间的分离,准确定位通信线路的故障点,降低漏判或误判故障点的情况,文章在参考前人研究结果的基础上,提出了光时域反射仪及检测方法。该方法在详细介绍光时域反射仪的相关理论知识后,依托小波变换模极大值监测信号奇异点理论,总结了小波变换模极大值降噪处理方法的计算公式,并将其与阈值去噪方法相结合实现设备的去噪处理。此类检测技术可有效去除光时域反射仪测试曲线噪声,提升通信光缆线路故障点定位点的准确性,可在今后的工作中进行推广和运用。
In order to effectively realize the separation between the signal and noise of the communication optical cable,accurately locate the fault point of the communication line,and reduce the missed or misjudged fault point,the article proposes the optical time domain based on the results of previous studies.Reflectometer and detection method.After introducing the relevant theoretical knowledge of optical time domain reflectometer in detail,this method relies on the wavelet transform modulus maximum monitoring signal singularity theory,summarizes the calculation formula of the wavelet transform modulus maximum denoising processing method,and compares it with the threshold The denoising method is combined to realize the denoising processing of the equipment.This type of detection technology can effectively remove the noise of the optical time domain reflectometer test curve and improve the accuracy of the fault location of the communication optical cable line.It can be promoted and used in future work.
