Title: Production of optical fiber preform and device therefor
Inventor: NAKANO MASAAKI
IPC: G02B6/00
Filed: 1993-11-24
Abstract: PURPOSE:To efficiently produce a thermophoresis effect and to increase the deposition rate by injecting a cooling inert gas around a fine glass particle-contg. flame projected from a torch to prevent the diffusion of the fine glass particles in the longitudinal direction of a glass seed rod and keeping a great temp. difference between the surface of a soot deposit and the fine particle. CONSTITUTION:An optical fiber preform producing device shown in the figure consists of a reaction chamber 1, torch 2, fine glass particle-contg. flame 6, glass seed rod 7, soot 8, exhaust duct 9 and surrounding tube 10. The flame 6 projected from the torch 2 is passed through the guidepath of the tube 10 and blown against the soot 8. The cooled inert gases 30 and 40 such as nitrogen blown out from the blowoff port of the tube 10 are blown against a site close to the left and right of the soot 8 deposit surface, and hence the flame 6 tending to flow to the left and right in the longitudinal direction of the soot 8 is pushed back to the soot 8 deposit surface.
