    • A method of making optical fibers that includes controlled cooling to produce fibers having a low concentration of non-bridging oxygen defects and low sensitivity to hydrogen. The method may include heating a fiber preform above its softening point, drawing a fiber from the heated preform and passing the fiber through two treatment stages. The fiber may enter the first treatment stage at a temperature between 1500 ºC and 1700 ºC, may exit the first treatment stage at a temperature between 1200 ºC and 1400 ºC, and may experience a cooling rate less than 5000 ºC/s in the first treatment stage. The fiber may enter the second treatment stage downstream from the first treatment stage at a temperature between 1200 ºC and 1400 ºC, may exit the second treatment stage at a temperature between 1000 ºC and 1150 ºC, and may experience a cooling rate between 5000 ºC/s and 12,000 ºC/s in the second treatment stage. The method may also include redirecting the fiber with a fluid bearing device or an air-turn device.
    • 制造光纤的方法包括控制冷却以产生具有低浓度的非桥接氧缺陷和对氢的低敏感性的纤维。 该方法可以包括在其软化点之上加热纤维预制件,从加热的预成型件拉伸纤维并使纤维通过两个处理阶段。 纤维可以在1500℃至1700℃之间的温度下进入第一个处理阶段,可以在1200ºC至1400ºC之间的温度下退出第一个处理阶段,在第一次处理中可能会遇到低于5000ºC/ s的冷却速度 阶段。 纤维可以在1200℃至1400℃之间的温度下进入第一处理阶段下游的第二处理阶段,可以在1000℃至1150℃之间的温度下退出第二处理阶段,并且可能经历的冷却速率在5000ºC/ s和12,000ºC/ s在第二处理阶段。 该方法还可以包括用流体轴承装置或空气转动装置重新定向纤维。

    • The invention relates to a method and to an apparatus for the continuous manufacture of a mineral fibre felt. The apparatus comprises a melting furnace (1), means (4) for introducing raw material into the furnace, and a discharge outlet (5) for the mineral melt in form of a melt flow, a device (6) for producing fibres from the melt, and means (8, 9) for collecting these fibres to a fibre felt (7). The apparatus further comprises a device (11) for measuring a parameter of the fibre felt (7) which depends on the melt flow, or for measuring the mass flow through the fiberizing apparatus, a control device (P) where these measured values are compared with set values for the same parameters, and a device, controlled by the control device (P), for regulating the melt flow by e.g. regulating the size of the melt outlet (5) on the basis of the difference between the measured values and the set values of the said parameters.
