A distributed optical fiber sensor based on Raman and Brillouin scattering is provided. The distributed optical fiber sensor includes a semiconductor FP cavity pulsed wideband optical fiber laser (), a semiconductor external-cavity continuous narrowband optical fiber laser (), a wave separator (), an electro-optic modulator (), an isolator (), an Er-doped optical fiber amplifier (), a bidirectional coupler (), an integrated wavelength division multiplexer (), a first photoelectric receiving and amplifying module (), a second photoelectric receiving and amplifying module (), a direct detection system (), a narrowband optical fiber transmission grating (), a circulator () and a coherence detection module (). The temperature and the strain can be measured simultaneously, and the signal-to-noise ratio of the system is enhanced.
