Abstract

PURPOSE:To thickly deposit a porous base material for a clad in a stable manner by parallelly arranging a plurality of torches in the side of the base material and allowing the flames to interfere in the deposition of said base material. CONSTITUTION:A porous base material for a core is grown on the tip of rodlike glass sintered body 32 in the axial direction with torch 31 for synthesizing glass fine particles. At this time, torches 36 for synthesizing fine particles for a clad are parallelly arranged in the side of the base material at positions where the flames of torches 36 interfere. Thus, the disorder of the growing surface in shape due to irregular flames is inhibited. The surface temp. of the material at the interference position is measured with optical pyrometer 37, and the flame positions are set not to form a low temp. region. By this method the synthesized clad to core diameter ratio is made larger, the growth of porous base materials is stabilized, and a single mode optical fiber with less loss is obtd.
