METHOD FOR PRODUCING OPTICAL FIBER USING LINEAR NON-CONTACT FIBER CENTERING

An optical fiber production system and method are provided for producing optical fiber. An optical fiber is drawn from a preform in a furnace and passes through a treatment device under a controlled reduced pressure or partial vacuum in the range of 0.01 to 0.8 atm. The treatment device cools the ba...

Zusammenfassung:An optical fiber production system and method are provided for producing optical fiber. An optical fiber is drawn from a preform in a furnace and passes through a treatment device under a controlled reduced pressure or partial vacuum in the range of 0.01 to 0.8 atm. The treatment device cools the bare optical fiber as it cools to a temperature range of at least 1,600° C. to 1,300° C. A non-contact fiber centering device is located near an exit of the treatment device to provide linear centering of the optical fiber as it exits the treatment device.
