      Optical fiber line, considered to be highly effective for signal transmission, sometimes suffer from fiber cut resulting in signal loss. It is highly desired that the exact cut location is found by use of fiber length so that entire fiber cable need not be replaced. An optoelectronic instrument OTDR (Optical Time-DomainReflectometer) is used to find the position of the cut along the fiber length. There is the need to find the physical location on the GIS map which can provide the exact location where the replacement of fiber or maintenance activity has to be carried out. This paper proposes Vincenty’s formula to be used for fiber cut localization using GIS mapping which assumes the Earth to be oblate spheroid instead of exact sphere. This method will be highly accurate than any other method for exact localization of fiber cut.
