Abstract: 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.

Abstract: The bushing balance controller (18) is an electronic device which measures the voltage drop across each segment of a multiple segment glass fiber forming bushing (10) and measures the current flow in the bushing. The device uses these measurements to produce error signals proportional to the difference in the set point temperature and the instantaneous temperature of each segment of the bushing. The device diverts current from each segment of the bushing whose error signal is greater than the average of the error signals for all segments of the bushing. The device also sums all error signals and passes this signal to a bushing controller (14) which adds current to the bushing when the sum of the error signals falls below a preset value.
