DISTRIBUTION MANAGEMENT OPTICAL FIBER, ITS MANUFACTURING METHOD, OPTICAL COMMUNICATION SYSTEM EMPLOYING THE OPTICAL FIBER AND OPTICAL FIBER BASE MATERIAL |
摘要 |
The present invention relates to a dispersion-managed optical fiber which can be manufactured easily and has a structure which enables the easy connection thereof with other optical fiber and the like. The dispersion-managed optical fiber is a silica-based optical fiber ensuring its single mode at a predetermined wavelength within a signal wavelength band, in which first portions each having a positive chromatic dispersion and second portions each having a negative chromatic dispersion are arranged alternately and adjacent to each other. In the dispersion-managed optical fiber, the dopant concentration is made uniform in the longitudinal direction and, corresponding to the above-mentioned first and second portions, the refractive index of a glass layer not doped with GeO2 as a dopant is adjusted or the residual stresses in glass layers are changed. <IMAGE> |
