摘要： A multi-nozzle type burner is used for producing a porous glass preform, the burner having small variations in deposition efficiency with the burner tip being not burned even when axial shift occurs at the concentric multi-tube part of the burner. The present invention provides a burner for producing a porous glass preform with a concentric multi-tube structure, comprising a glass material gas jet port in a center, a plurality of gas jet ports concentrically disposed outside the glass material gas jet port, and small-diameter gas jet ports which are disposed in a line or a plurality of lines concentrically to the glass material gas jet port so as to be enclosed in one of the gas jet ports other than the gas jet ports in the center and at an outermost side, the small-diameter gas jet ports in the same line having an identical focal length. In the present invention, the gas jet ports disposed outside the gas jet port enclosing the small-diameter gas jet ports are each reduced in diameter in a direction toward a burner tip, and satisfy a relationship of L1>L2>L3> . . . >Ln, where L1, L2, L3, . . . Ln represent lengths from the burner tip to diameter-reduction start positions of the outside-disposed gas jet ports in this order from the inside, respectively, so that the more outward the gas jet port is located, the closer to the burner tip the diameter-reduction start position of the gas jet port is.

摘要： A core torch for fabricating a single-mode optical fiber preform wherein fine glass particles are produced eccentrically with respect to the center area of a flame stream, the core torch being so arranged as to blow the flame stream at an angle inclined to a seed rod. The porous glass body forming the core is grown on one end of the rod and in the direction of the axis of the rod. A cladding layer is formed on the periphery of the porous glass core body by at least one torch for forming the cladding. The obtained porous glass body is heated and vitrified into a transparent glass body, which is sealed in a silica tube for jacketting to form a single-mode optical fiber preform. At least one exhaust port is disposed within a distance of 1 mm to 50 mm from the periphery of the porous glass body and in the vicinity of the growing surface of the glass body to exhaust residual glass fine particles and undesired gases. A porous glass body having a diameter of 20 mm or less is easily formed. Single-mode optical fiber having a cladding-to-core-diameter ratio of 3 or more is fabricated by the VAD method. Accordingly, a long-length and low-loss single-mode optical fiber is mass-produced.

摘要： A method of fabricating an optical fiber preform wherein a synthesizing torch is inclined between 10.degree. and 60.degree. with respect to the rotation axis of a seed rod. Moving the rod while rotating it, a glass raw material gas and a flame forming gas are blown out individually from the torch to synthesize glass particles which are deposited onto one end of the rod, so that a cylindrical porous preform is grown in the direction of the rotation axis of the rod. Then the porous preform is heated at a high temperature to vitrify the porous preform into a transparent optical fiber preform. At least one exhaust port is disposed at a distance of 1 mm to 50 mm from the periphery of the porous preform and in the vicinity of the growing surface of the porous preform. In fabricating the porous preform the outer diameter fluctuations are small, and the preform is formed stably without formation of cracking on the periphery of the preform.
