摘要：The present invention relates to a method and a device for manufacturingoptical preforms, in which one or more layers of glass, doped or undoped, are depositedonto the internal surface of a hollow substrate tube, which deposition is effected bysupplying one or more reactive gas mixtures of glass-forming compounds tot the interiorof the hollow substrate tube and subsequently generating a non-isothermal plasma inthe hollow substrate tube, after which the preform is subjected to a contraction processfor the purpose of forming a massive rod, from which optical fibres are drawn.
