Abstract: Apparatuses and methods for processing optical fiber preforms are disclosed. According to one aspect, an apparatus generally includes a furnace body and a muffle disposed within the furnace body. A space between the muffle and the furnace body defines a first interior volume. The muffle defines a second interior volume sealed from the first interior volume. An annulus gas is supplied to the first interior volume and a process gas is supplied to the second interior volume. A differential pressure gauge is coupled to the interior volumes. A flow controller is coupled to at least one of the gas sources and to the differential pressure gauge. The flow controller receives a differential pressure signal from the differential pressure gauge and adjusts a flow of a gas such that the pressure differential between the first interior volume and the second interior volume is minimized.

Abstract: A method of manufacturing an optical fiber, the method including drawing a bare optical fiber from an optical fiber preform along a draw pathway. The method further includes during the drawing step, moving a first fluid bearing from a first position to a second position, the first position being removed from the draw pathway and the second position being disposed in the draw pathway such that the movement of the first fluid bearing to the second position causes at least a first portion of the draw pathway to change direction.

Abstract: A system and methods are described herein for preheating a preform in a preheater furnace and then transferring the preheated preform to a consolidation furnace for chemical treatment and sintering the preform into a clear glass which can be drawn into optical fiber. In addition, the preheater furnace is described herein which is configured to heat the preform per a predetermined heat-profile until the preform is uniformly heated to a temperature above 1000° C.
