Abstract

Data for "100km Single-ended Distributed Vibration Sensor based on Remotely Pumped EDFA" published in Optics Letters Fig. 2 Measured Rayleigh backscattered signal (blue) with combined EDFA and Raman amplification using a launched power of 40mW combined with a 500mW 1480nm pump; (orange) without the use of optical amplification with 220mW launched power. (otdr.mat) Fig. 3 3D map of the strain distribution along the sensing fiber as a function of a) time and distance and b) frequency and distance. (3a.mat &3b.mat) Fig. 4 2D cross-section of the 3D diagram of Fig. 3 at a specific location on the sensing fiber where strain is applied (99.5km). a) The 2D cross-section in time-domain and, b) the 2D cross-section in the frequency-domain at fixed point and c) the 2D cross-section in the frequency-domain at fixed frequency. (time2d.mat, freq2d.mat, 4c.mat) Fig. 5 Strain response of the fiber to the PZT input voltage for 10Hz sinusoidal signal measured by the DVS. (pzt.mat)
