Matlab data file for 80km BOTDA system. A 300mw pump pulse with 20 ns is used. The frequency sweeps from10.88 GHz to 11.19 GHz with 1 MHz step and 512 averages per trace are used. A 5m hotspot placed at the end of the 80-km sensing fiber is produced by heating it up to 76 °C, while the rest of the sensing fiber has been maintained at ambient temperature (26°C). The FWHM of BGS is about 50Mhz.
