    摘要: A method and an apparatus for producing a glass preform having a uniform J ratio by adjusting the weight of glass particles to be deposited on a starting glass rod. The method uses an OVD method by which glass particles are successively deposited on an external cylindrical surface of a starting glass rod to create a growing soot layer thereon and the soot layer is then vitrified into a transparent glassy body, wherein the glass particle deposition is conducted by adjusting an amount of glass particles to be deposited based on data of J ratio fluctuations (where the J ratio is a ratio of an outer diameter of a glass preform to an outer diameter of a starting glass rod) of a previously produced glass preform in its longitudinal direction so that the glass preform to be produced can attain a uniform J ratio in its longitudinal direction.

    摘要: In a method in which a rotating starting rod and glass particle synthesizing burners are relatively reciprocally moved in parallel with each other, so that while a turn-back position of the relative movement is shifted in a predetermined direction, glass particles (soot) are deposited on a surface of the starting rod to thereby produce a glass particles deposit, the deposition of soot is performed under a condition that an interval between a burner located at any one of both ends in a direction of the relative movement and a burner located adjacent thereto is shorter than another interval between any two of intermediate burners other than the two burners located at the both ends.

    摘要: In a known method for producing an SiO2 blank, SiO2 particles are formed in a burner flame of a deposition burner and are deposited under the effect of an electrical field on a substrate. Starting therefrom, in order to indicate a simple and inexpensive method by means of which blanks can be produced with a predetermined, in particular axially homogeneous, mass and density distribution, it is suggested according to the invention that the geometrical shape of the burner flame (8) is adjusted by the effect of the electrical field (9) in dependence upon the geometrical parameter of a deposition surface (12; 21) of the substrate (1) that is assigned to the burner flame (8). An apparatus suited for performing the method comprises a substrate, at least one deposition burner for producing SiO2 particles in a burner flame assigned to the deposition burner, a measuring device for sensing a geometrical parameter in the area of a deposition surface of the SiO2 blank, and a pair of electrodes connected to a source of voltage for producing an electrical field (9) which is operative in the area of the burner flame and is adjustable in dependence upon the geometrical parameter of that deposition surface (21; 21) of the substrate that is assigned to the burner flame (8).

    摘要: A plurality of glass particle synthesizing burners are disposed opposite to a rotating starting rod. The starting rod and the glass particle synthesizing burners are relatively reciprocally moved to each other in parallel to the axial direction, so that glass particles synthesized by the burners are sequentially deposited on the surface of the starting rod. The movement is stopped and restarted repeatedly once or more than once during one reciprocal movement.

    摘要: 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.
