A novel distributed fiber-optic sensor based on Wavelength Division Multiplex (WDM) for determining the position of disturbances is presented. The configuration and operating principle of the system is illustrated. The location principle and the method for the detection system are analyzed. Based on the initial method in the frequency domain, the system realizes the disturbances location using the WDM technology to compare the signals which are the same vibration corresponding to different light sources and light paths. Theory analysis and experiment results show that the proposed algorithm can realize the detection and location of the multipoint disturb signals rapidly and effectively, this method is simply and can be obtained easily, it could increase the length of fiber-optic sensors which has high measurement sensitivity and location precision.
