Abstract: A method for producing a glass preform for an optical fiber comprises (a) dehydrating a porous preform composed of GeO2-SiO2 fine glass particles, (b) heating the preform under oxygen gas atmosphere contg. at least F-system gas so as to be dehydrated at a temp. at which violent shrinkage does not occur, and then (c) heating the preform under He gas atmosphere at such temp. that the preform is throughly vitrified. The fine glass particles are composed of P2O5, GeO2 and SiO2.
