OPTICAL FIBER AND METHOD OF MANUFACTURE THEREOF |
摘要 |
<p>This invention relates to an optical fiber having a structure that effectively reduces transmission loss and bending loss. An optical fiber according to this invention is an optical fiber mainly comprised of silica and including a core region and a cladding region covering the core region. The core region is doped with chlorine so as to have a refractive index higher than that of pure silica. The cladding region is doped with fluorine so as to have a refractive index lower than that of pure silica. The optical fiber, in particular, is characterized in that a peak value of a relative refractive index difference of the core region with respect to a refractive index of pure silica is 0.05% or more. <IMAGE></p> |
