ABSTRACT:
In a method of forming a preform from which an optical fibre can be drawn, successive layers of matter (24, 28) are deposited by vapour deposition on a rotating cylindrical body (10) which is traversed by a heat source (15). For the deposition of at least two successive layers (24, 28), a rate of rotation of the body and/or a rate of traverse of the heat source is selected so as to generate in one of said layers a surface profile different to a surface profile generated in the other said layer.
