Paper Abstract

Simultaneous distributed strain and temperature measurement based on Brillouin frequency shift (BFS) was demonstrated using a dual-Brillouin-peak single-mode (SM) optical fiber. The fiber is designed and fabricated with enhanced Brillouin gain of higher-order acoustic modes so that the gains of the multiple Brillouin peaks are at a similar level. In a 25-kilometer sensing length with 5-meter spatial resolution, the achieved temperature resolution is 2°C and the strain resolution is 40 microstrain.
