| Abstract: | Chromatic dispersion in optical fiber would bring transmitting signal distortion, the capability of the optical fiber communication system is limited. It is greatly important that the parameters of chromatic dispersion and the expanding of the optical pulse are measured accurately after long distance transmission. The basic theory of chromatic dispersion in optical fibers is discussed and the pulse expanding is analyzed on emphasis. A set of apparatus for measuring chromatic dispersion of multimode fibers is manufactured by us and applied in teaching and engineering expenment now. |
