Abstract

A method of manufacturing an optical transmission fibre comprises forming glass particles by subjecting glass raw material gas to flame hydrolysis, and then supplying the glass particles onto a starting member so that the glass particles are laminated thereon and successively grown to produce a cylindrical glass particle body. The cylindrical glass particle body is then sintered to produce a transparent glass cylinder 13, which is subsequently inserted into a quartz glass pipe 14 to provide the assembly of the transparent glass cylinder 13 and the quartz glass pipe 14. The assembly is heated (15) to melt the glass cylinder and the quartz glass pipe together and the assembly is drawn into a thin fibre 16. <IMAGE>
