Submarine Pipeline Safety Inspection Based on OTDR Distributed Optical Fiber
A kind of submarine pipeline safety inspection technology based on optical time domain reflection (OTDR) distributed optical fiber sensing system is proposed. The composition and operation principle of the system are analyzed. The positioning structure and the methods of the inspection system are described. The disturbance position is obtained through the time delay between injection pulse and received signals. Theoretical analysis and inspection results show that the inspection system has better stability and positioning precision.
