A 150-km long distance fiber Bragg Grating (FBG) temperature and vibration sensor system was proposed and demonstrated by using the stimulated Raman amplification. It can achieve 150-km measurement range by using a low power 1480-nm laser as the Stokes of the pump laser at 1395 nm in the progress of stimulated Raman amplification. And the whole system only consist one Raman pump laser source with 1-W power at 1395 nm, a low-power 1480-nm laser and two segments of erbium doped fiber (EDF) at the location of 50 km and 75 km separately.
