One of the biggest trends in optic fiber inspection is the use of automated and robotic systems. they can inspect large quantities of fibers in a shorter amount of time, which saves. Traditional inspection methods often suffer from low efficiency, prompting the exploration of fiber fingerprint technology for intelligent inspection and fault prediction of optical cable resources. Bridges, tunnels, dams, pipelines, and underwater structures all need thorough and regular inspections. as the demand. Distributed Strain and Temperature Sensing (DSTS) systems provide an effective way to monitor the quality or working status of fiber optic cables or power cables carrying optical fibers. Manual inspection in optic cable quality cannot catch up with the development of optic cable industry due to its low detection.
