摘要： 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° C. and 1700° C., may exit the first treatment stage at a temperature between 1200° C. and 1400° C., and may experience a cooling rate less than 5000° C./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° C. and 1400° C., may exit the second treatment stage at a temperature between 1000° C. and 1150° C., and may experience a cooling rate between 5000° C./s and 12,000° C./s in the second treatment stage. The method may also include redirecting the fiber with a fluid bearing device or an air-turn device.

摘要： A fluid bearing for directing optical fibers during manufacturing is presented. The fluid bearing provides a flow of fluid to levitate and direct an optical fiber along a process pathway. The optical fiber is situated in a fiber slot and subjected to an upward force from fluid flowing from an inner radial position of the fiber slot past the optical fiber to an outer radial position of the fiber slot. The levitating force of fluid acting on the optical fiber is described by a convex force curve, according to which the upward levitating force on the optical fiber increases as the optical fiber moves deeper in the slot. Better stability in the positioning of the optical fiber in the fiber slot is achieved and contact of the optical fiber with solid surfaces of the fluid bearing is avoided. Various fluid bearing structures for achieving a convex force curve are described.

摘要： The invention relates to a method of applying a coating liquid to an optical fiber. An optical fiber is drawn through a guide die into a pressurized coating chamber and through the pressurized coating chamber to a sizing die. The pressurized coating chamber contains a coating liquid. The method includes directing coating liquid in a direction transverse to the processing pathway of the optical fiber in the pressurized coating chamber. The transverse flow of coating liquid counteracts detrimental effects associated with gyres that form in the pressurized coating chamber during the draw process. Benefits of the transverse flow include removal of bubbles, reduction in the temperature of the gyre, improved wetting, homogenization of the properties of the coating liquid in the pressurized coating chamber, and stabilization of the meniscus.

摘要： According to some embodiments a method of processing an optical fiber comprises the steps of: (i) drawing the fiber at a drawing rate of at least 30 m/sec; and (ii) cooling the drawn fiber in a gas at an average cooling rate less than 5000° C./s, such that said cooling reduces the temperature of the fiber from an entering temperature in the range between 1500° C. and 1700° C. to another temperature in the range between 1200° C. and 1400° C., the gas being at a temperature between 800° C. and 1500° C.; and the thermal conductivity κ of the gas being not greater than 1.5×10−4 cal/cm-s-K for at least one temperature within a range of 800° C. to 1500° C. at one atm (atmosphere) pressure absolute.
