摘要： A multi-functional method and apparatus are disclosed for producing a low hydroxyl ion-containing core rod from a tube suitable for the production of low-water optical fibers. The method and apparatus combine the use of process steps of (1) hermetically sealing a tubular quartz handle of a tubular porous core preform to a tube used to feed the porous preform into a sintering furnace, (2) dehydration and sintering, and (3) elongation of the sintered preform under vacuum, all without exposing the preform's central aperture surface to ambient atmosphere.

摘要： An outside chemical vapor deposition apparatus is disclosed for depositing porous glass-forming material onto a target rod to form a cylindrical body, with substantially higher efficiency than could prior apparatus. The apparatus includes two separate burner arrays, one array optimized for depositing the material during an initial stage of the process, when the cylindrical body has a relatively small diameter, and the other array optimized for depositing the material during a later stage of the process, when the cylindrical body has a relatively large diameter. In addition, each burner array can include a plurality of burners, with each burner azimuthally angled relative to the apparatus' air-flow axis, and with adjacent burners angled in opposite directions relative to that axis, to minimize the density gradient within the deposited porous material.

摘要： An improved method and apparatus is disclosed for sintering large, cylindrical, porous bodies used in the manufacture of high-quality optical fiber preforms. The apparatus has a compact, simplified structure, as compared to comparable apparatus of the prior art. The apparatus includes two separate support/slide assemblies that support the porous body throughout the sintering process. A first support/slide assembly engages a special handle for the porous body during a first stage of the process, in which the body is lowered into a furnace muffle. A second support/slide assembly then engages the porous body's handle during a second stage of the process, in which the body is controllably moved through a hot zone of the furnace, for dehydration and sintering of the body into a dense glass optical fiber preform. The body's handle is specially configured to allow both support/slide assemblies to be engaged with it simultaneously, whereby the sintering process can be carried out without the need for separate support structure during the switchover from the first support/slide assembly to the second support/slide assembly.
