Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing an optical fiber, said method comprising the steps of: drawing a bare optical fiber from a preform in a furnace; reducing pressure in at least one of the furnace and a treatment device such that the pressure in the at least one of the furnace and treatment device is in the range of 0.01 to 0.40 atm; centering the bare optical fiber downstream of the at least one of the furnace and the treatment device, said centering achieved with…
