Full Link SNR Equalization DAS System over 80km Based on Gradient Discrete Scattering Enhanced Fiber

Not Accessible

Your library or personal account may give you access

Abstract

We proposed a full-link SNR-equalization DAS based on gradient discrete scattering enhanced fiber with backscattering rates increase gradually according to optical loss. The experimental results show a 15pε/√Hz strain resolution over 80km.
