基于拉曼放大和半导体光放大的BOTDA
Brillouin Optical Time Domain Analysis System Based on Raman Amplification and Semiconductor Optical Amplifier
摘要
Abstract
A Brillouin optical time domain analysis (BOTDA) system based on Raman amplification has been theoretically analyzed. The detected probe waveshape has been simulated by using the probe-pump coupled equations combined with Raman. The numerical simulation shows that the bi-directional Raman amplification is very effective for enhancing the measurement accuracy. The experimental exploration of the BOTDA with Raman amplification and semiconductor optical amplifier (SOA) has been demonstrated. The experimental results are in good agreement with the theoretical analysis. The results show that a temperature resolution of 1 ℃ was achieved over a sensing distance of 49.6 km with a 40 m spatial resolution.关键词
