Abstract
A method of producing an optical fiber is provided that includes the steps of flowing a first gas into an optical fiber draw furnace. The first gas is passed through a heated section configured to contain and heat a glass source from which the optical fiber is drawn, passing the first gas through a muffle which defines a capture chamber. A portion of the first gas is removed through at least one reclaim port operatively coupled to the capture chamber. A second gas flows into a gas screen at a rate configured to substantially recover a pressure drop associated with removing the portion of the first gas.
