A simple 100-km long distance fiber Bragg grating sensor system was proposed and demonstrated. It can achieve 100-km measurement length with reflected Bragg wavelength spectrum of 30 dB signal noise ratio by using only one Raman pump laser source with 1 W power at 1395 nm and two segments of erbium-doped fiber at the locations of 50 and 75 km separately.
