Remote amplification in long range distributed Brillouin-based temperature sensors

Abstract

A remotely pumped EDFA combined with Raman amplification was used to enhance the performance of spontaneous Brillouin intensity-based temperature sensor. A temperature resolution of 5.7°C, spatial resolution of 20m was achieved at 88km.
