Abstract
We investigate and demonstrate experimentally a two-stage erbium-based amplifier with a larger amplified-spontaneous-emission light source for a long-distance fiber sensor by using strain-induced fiber Bragg gratings in the fiber systems. In a 20-km-long fiber sensor system, the sensor has a maximal ≈2.28-nm wavelength shift under a 1500-μm/m strain. [ABSTRACT FROM AUTHOR]
