摘要： Method and apparatus for producing glass products of predetermined shape. In the method, a perform is introduced into a furnace and heated to a temperature above the softening point of the glass. The heated portion is subjected to tensile forces and drawn from the furnace through an outlet opening. During processing, inert gas is fed into the furnace. According to the invention, the concentration of gaseous impurities in the furnace is maintained on the same level as in the inert gas fed into the oven. To prevent inflow of undesired gaseous components from the ambient air, a diffusion barrier is established by generating a barrier flow of inert gas in the inlet or outlet openings. This barrier flow has a direction of flow, which is opposite to the direction of the diffusion. The invention provides non-contacting sealing between the furnace and the preform while optimizing the consumption of protective gas. The invention also allows for simultaneous rotation of the preform.

摘要： An automatic quartz-tube leveling device for automatically measuring the leveling state of an optical-fiber preform on an on-line basis using a modified-chemical-vapor deposition (MCVD) technique is disclosed. A quartz tube is disposed in a horizontal supporting element such as a lathe. A measuring device is provided with a light-emitting device and a light-receiving device, interposing the quartz tube, for measuring an upper eccentric value and a lower eccentric value along a length of the quartz tube. A controller receives the measured upper and lower eccentric values from the measuring device, compares the measured values with predetermined reference values, and specifies a necessary leveling span of the quartz tube. A transfer device then moves to a necessary leveling span of the quartz tube to carry out leveling of the quartz tube, under control of the controller.

摘要： A dual seal system for retrofitting existing vapor deposition apparatus for starter tubes has a first tubular member which surrounds the chemical vapor delivery tube and forms a channel therewith for passage of starter tube gases to a stationary seal coupling member which, in turn, is connected to monitoring apparatus. A second tubular member surrounds the first tubular member and forms a passage therewith extending from behind a seal assembly in the starter tube to a bore in the coupling member connected to a buffer gas supply. The second tubular member also forms a third passageway with the interior wall of the arbor driving the starter tube and is held spaced therefrom by a perforated support member. The third passageway extends from a region behind the sealing system to a sealed buffer chamber in the coupling member, which is connected to a low pressure of vacuum source and to a pressure monitoring member.

摘要： In the P.C.V.D. process, in principal the quartz tube need not be rotated during the deposition of the glass layers. However, it has been found in practice that an improvement in the quality of the glass fibers can be obtained if the quartz tube is rotated regularly over an angle of 360.degree./n. n is preferably equal to an integer from 2 to 12.

摘要： An improved multimode optical fiber having substantially higher bandwidth and lower loss is made by controlling process parameters such as the volume of the silica which is deposited in each pass of a torch assembly (41) along a substrate tube (31) to form a preform tube which is collapsed to provide a preform (80) from which the optical fiber is drawn. As a result, the amplitude variation of the refractive index across each layer is controlled to be within desired limits. Should the volume of the silica deposited in each pass be controlled to control the amplitude variation, the thicknesses of the outermost deposited glassy layers in the preform tube are greater and those of the innermost layers are less than those of layers in a preform tube made by prior art MCVD processes. Because the difference in the index of refraction across each glassy layer is reduced, the bandwidth is enhanced and the loss of the drawn optical fiber is reduced over those properties of optical fiber drawn from preforms made by prior art MCVD processes. Inasmuch as the inventive process also allows a higher deposition rate than before, it may be used to produce single-mode optical fiber at lower costs than before achieved.
摘要翻译：通过控制工艺参数，例如沿着衬底管（31）沉积在焊枪组件（41）的每次通过中的二氧化硅的体积以形成预成型管，进行具有显着更高带宽和更低损耗的改进的多模光纤其被塌缩以提供从其中拉出光纤的预成型件（80）。结果，每层的折射率的振幅变化被控制在期望的范围内。如果控制每个通道中沉积的二氧化硅的体积来控制幅度变化，则预制管中最外面沉积的玻璃层的厚度更大，并且最内层的厚度小于由预制管制成的预成型管中的层的厚度现有技术的MCVD工艺。由于每个玻璃层上的折射率差异减小，带宽增加，并且拉制的光纤的损耗比从现有技术的MCVD工艺制成的预制件拉制的光纤的性能降低。由于本发明的方法还允许比以前更高的沉积速率，所以其可以用于以比实现之前更低的成本制造单模光纤。
