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: The dispersion shifted single mode optical fiber is manufactured by the stages of preparing a core member consisting of an inner core part made of a germanium-added quartz glass which optionally contains fluorine and an outer core made of a fluorineadded quratz glass having a refractive index smaller than that of the inner core part, making a glass tube made of a fluorine-added quartz galss having a refractive index smaller than that of the outer core part, inserting the core member into the glass tube, heating and fusing them together.
