Abstract: Optical Time Domain Reflectometer(OTDR) is an optoelectronic integration precision instrument that makes use of Rayleigh back scattering and Fresnel reflection in optical fiber for optical fibre link chacterization, it is widely used in fiber maintenance, construction, fault location and other measurements. In the dissertation, the design of an OTDR system is studied. Background theory of the system and detailed system design are described. A light pulse with 5000Hz frequency and the duty cycle of 1/200 is launched into an eight kilometer optical fiber link. The backscattered and reflected light is detected and measured. Experimental results have demonstrated the effectiveness of the designed system.
