| Abstract: | A cable health state monitoring system based on all-fiber sensor technology is studied.By an analytical research on the backscattering distribution fiber sense theory,the prototyping system is worked out successfully and applied to power cable tunnel which supervises the distribution of kilometers of cable′ running and environmental status along the line of fiber.The results prove that the system is able to supervise such status distribution as temperature,carrying capacity,stealing or invading of cables with embedded poly-cycle 20 km fiber,and then locate the measuring point. |

| Keywords: | distributed optic fiber sensing backscattering power cable health status monitering |
