Abstract

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.
