    With the development of modern communications, in order to meet the needs of Social development and technological progress the optical fibre communications has become the main communication medium for its high reliability and security. Fibre-optic cable is the channel for signal transmission. It is an important Component in the entire fibre-optic network. Once the fibre-optic cable fault happened, the entire communication system would be impacted seriously. When Fault occurs, it is important to find out, locate it accurately, and remove it quickly.In this report we have firstly described what a optical fiber cable is along with it we have explained the different techniques used in multiplexing of Optical fiber network. Then according to the causes and characteristics of fibre-optic cable fault, we use the Optical Time- Domain Reflectometer (OTDR) to test the line, determine the position and feature of the error point. Finally we get the solution to fix the problem.
