With the development of the telecommunication, optical fiber has been widely used. It has the characteristics of long distance transmission and large capacity, but it also has dispersion exists. The dispersion can be divided into some types. Mode dispersion plays a major role in multimode fiber, while chromatic dispersion or intramodal dispersion are the main mechanism in single mode fiber. Generally, it is quite important to test the dispersion and know the dispersion characteristics. The theoretical basis and experimental device, which are both based on the interference principle, have been introduced in detail. The device is used to measure the fiber dispersion characteristics of optical fiber and the results shows the validity of the theory and the designed test device.
