Abstract

Method of manufacturing optical fibres starting from a thick-walled glass tube (1), preferably a quartz tube, where one or more substances (4) which are to comprise the core of the optical fibre are either deposited and sintered directly on the inside of the thick-walled tube or alternatively on the inside of a thin-walled tube which is subsequently collapsed and inserted in the thick-walled tube, after which the thick-walled tube is heated to its collapsing temperature with the aid of microwave energy supplied to a cavity in which a part of the tube is to be found. The invention is distinguished in that the material from which the thick-walled quartz tube is manufactured is caused to contain contaminants in the form of one or more substances which give rise to a dissipation factor for converting the microwave energy to heat in said material which is sufficient for enabling heating the quartz tube (1) to its collapsing temperature and in that a zone is arranged for braking or substantially preventing diffusion of said contaminants from the quartz tube (1) to the core, said zone being created between the tube and the substance or substances which are to comprise the fibre core.
