AB High sensing resolution in long-distance distributed fiber optic sensors, such as Brillouin Optical Time Domain Analysis(BOTDA), cannot be trivially achieved due to several issues including self-phase modulation, resolution-uncertaintytrade-offs and fiber attenuation. These problems could be fixed by the use of differential pulse-pair techniques incombination with Raman amplification. In this work we present a Differential Pulse-width Pair (DPP) Raman-assistedBOTDA sensor, that can achieve 1 meter resolution in a 100 km range.
