Fast Brillouin Optical Time-Domain Reflectometry with Simplex Coding and Coherent Detection
We propose a fast Brillouin optical time-domain reflectometry scheme using simplex coding and coherent detection. Brillouin frequency shift measurement uncertainty of 0.38 MHz is achieved for 10 km fiber and 4.0 m spatial resolution.
