The invention discloses a chaotic visible laser-based optical fiber fault positioning device and a positioning method thereof. The positioning device comprises a chaotic visible laser emitting device, an optical fiber coupler, an optical circulator, a photoelectric detector, an A/D (Analog/Digital) converter, a signal processing device and a display device. Chaotic visible laser signals emitted by the chaotic visible laser emitting device generate obvious visible bright spots at a fault point (11) of an optical fiber line to be tested (4) due to transmission, and the accurate positioning of the fault point can be realized by finding the visible bright spots in a range of the distance between a detection point and the fault point (11). According to the positioning device and the positioning method, the chaotic visible laser is used as a detection light source, and a chaos-related fault point detection technology and a visible optical fiber fault point detection technology are integrated, so that the fast and accurate detection and positioning of the optical fiber fault point is realized, and the problem that the optical fiber fault point is easily measured and not easily positioned is solved.
