| Abstract: | Fiber chromatic dispersion is not only a major factor restricting the transmission velocity and distance but also a problem pressed for urgent solation in high-speed light communication systems at present. In this paper the components of single-mode fiber dispersion are introduced and the formula of calculating pulse expansion for chroma dispersion is deduced. Moreover, the progress of measuring chromatic dispersion by modulating phase is analyzed and the necessity for compensating chromatic dispersion is parsed while the theory of the chirped fiber bragg grating compensation dispersion is given and the developmental trend of single-model fiber is expounded . |

| Keywords: | chromatic dispersion group delay pulse expansion chirped fiber bragg grating |
