Abstract: The optical fiber glass preform is prepd. by heat treatment in fluorine-contg. atmos. of shoot preform. Fine glass particles deposit is impregnated with fluorine at such a temp. that it is kept in porous state, is then vitrified under a F compound-contg. atmos. in a furnace at 1100-1400 C. The glass particles deposits are uniformly doped wiht F, and impurity content of the preform is lowered in a large extent.
