摘要
光时域反射仪是一种测量光纤衰减特性的仪器,但其所采集的光纤后向散射数据有很大的噪声,不利于光纤事件的分析。小波变换具有良好的时频域特性,采用小波变换对采集数据实现去噪处理,得到了良好的效果。
OTDR is an important device used to automatically analyze the fiber's attenuation performance, but fiber's backscatter data has much noise, which has bad effect on fiber's events analysis. Wavelet transform has a good performance in both time and frequency field. A denoising analysis to the data using wavelet transform is given with better precision.
