ABSTRACT OF THE DISCLOSURE This invention relates to a method of fabricating glass fiber optical transmission lines. In accordance with the invention, an intermediate preform structure with a core-to-clad ratio greater than that desired in the ultimate fiber is obtained by depositing the core by means of a MCVD (Modified Chemical Vapor Deposition) process, prior to the completion of the cladding. Subsequent to internal core deposition, additional material is added externally to complete the cladding thereby yielding an optical fiber preform with the desired core-to-clad ratio.
