A technique of event detection and location in OTDR-tested data based on Gabor transform

In recent years, more and more optical fiber cable has applied to the long haul trunk, and the optical network has become the backbone of communication network because of the rapid development of optical fiber communication. So higher requirement for management of optical cable network is brought forward. This paper analyzes the technique fo monitoring optical cable, gives an event analysis algorithm based on Gabor transform and minimum description length (MDL) criterion, and analyzes the performance of the algorithm.
