    Abstract: A optical-fiber preform is produced by the stages of: inserting a quartz glass rod (3) as core in a tube (2) as cladding material, injecting via an inlet line (5) a gaseous mixt. of Si halide, F- contg. cpd. and O2 gas (where Si:F ratio is more than 1/300 and less than 1/5), heating the composite to 1000-1600 deg.C with rotating, replacing the atmos. with a gaseous mixt. of halogen-contg. cpd. and O2, reheating and fusing the core and cladding together at not less than 1900 deg.C.

    Abstract: A method for producing a glass preform for a single mode optical fiber comprising a core and cladding comprises (a) depositing fine glass particles of a glass raw material on the periphery of a cylindrical seed having a smooth and clean outer surface to form a deposited soot by flame hydrolysis, (b) drawing the seed from the deposited soot, (c) inserting a core glass rod in a hollow portion of the glass soot to form a complex body, and (d) drying and sintering the complex body.
