Design Of A Specially Spherical-Glowing Optical Fiber

Since the Corning company of USA has succeed in developing the first practical silicon optical fiber in the world at the beginning of the seventies of the 20th century, the optical fiber communication taking optical fiber as media and optical fiber transmission technology has been fast developed. In recent years, as the research of the transmission technology of optical fiber is being deepened constantly, its characteristics and using has been paid attention to by the people, especially in the medical treatment, application of respect of measuring and decorating.Through surveying and studying and comparing on domestic and international and of different optical fiber technology, the spherical-glowing optical fiber is not enough in luminance in medicine at the present, and it has influenced its medical result greatly. On the basis of existing condition, this laboratory develops a study of specially spherical-glowing optical fiber. So this way has some realistic meaning and research value. The main content of this text is as follows:1. The basic theory and optical fiber technology transmission in the optical fiber are detail discussed.2. The characteristics of the optical fiber transmission theory are offered, and pointing out emphatically the loss and the chromatic dispersion is the main performance indexes which influence the optical fiber transmission. The loss limits the distance of the optical fiber transmission systematic, The chromatic dispersion limits the capacity of systematic transmission.3. A new study of specially spherical-glowing optical fiber is present in this paper, A large core silica optical fiber is melt the ball and is spread all scattering body evenly on the round spherical terminal surface, which is melt the ball to the spherical terminal surface again, thus getting the output optical fiber needed.4. Designing the system of testing the specially spherical-glowing optical fiber.
