Abstract

PURPOSE:In the production of optical fibers for communication, an optical fiber of a wide band and low loss is produced by fusing plural glass layers whose refractive indices become gradually smaller on the outside wall of core glass while passing the core glass in molten glasses of different refractive indices.
