Bi-Directional Brillouin Optical Time Domain Analyzer System for Long Range Distributed Sensing

Bi-Directional Brillouin Optical Time Domain Analyzer System for Long Range Distributed Sensing

We propose and experimentally demonstrate a novel scheme of bi-directional Brillouin time domain analyzer (BD-BOTDA) to extend the sensing range. By deploying two pump-probe pairs at two different wavelengths, the Brillouin frequency shift (BFS) distribution over each half of the whole fiber can be...
