Zusammenfassung: | The invention discloses a device and a method for vibration detection and automatic positioning of an optical cable routing detector, the device comprises a narrow linewidth laser, an acoustic optical modulator, a first erbium-doped optical fiber amplifier, a circulator and a wavelength division multiplexer which are connected in sequence, the wavelength division multiplexer is externally connected with a Raman pump laser and a sensing optical fiber, and the Raman pump laser is externally connected with the acoustic optical modulator. A first port of the circulator is connected with the first erbium-doped optical fiber amplifier, a second port of the circulator is connected with the wavelength division multiplexer, and a third port of the circulator is connected with the second erbium-doped optical fiber amplifier, the photoelectric detector, the electric signal acquisition and signal processing module and the signal generator which are connected in sequence; and the acoustic optical modulator and the electri |
