The Application of GIS in the Optical Cable Fault Location

Aimed at the difficulty of the optical cable-maintaining. This paper issues a method for optical cable fault location on GIS (Geographic Information System) and expert system. According to the principle and application of the OTDR (Optical Time Domain Reflectometer) and requirement of the principle To improve the optical cable-maintaining efficiency, the rules of the optical cable-maintaining, a GIS for optical cable-maintaining is built. To improve the optical cable-maintaining efficiency, an algorithm for optical cable fault location has been put forward.
