Provided herein is a method of and system for processing an optical fiber. The method includes the steps of drawing an optical fiber in a drawing direction along a process pathway through a coating chamber comprising an inlet and an outlet, and a coating liquid volume to coat the optical fiber; supplying the coating liquid through the inlet, the coating liquid exiting the coating chamber through the outlet; and recirculating to coating liquid exiting the coating chamber to the inlet.

An oxidizer head assembly includes a head body defining an inlet flange, an outlet flange, and a wall, where the inlet flange, the outlet flange, and the wall define a cavity positioned between the inlet flange and the outlet flange, a plurality of nozzles extending through the cavity, a fuel inlet in communication with the plurality of nozzles, where a fuel passes through the fuel inlet and the plurality of nozzles, a shield gas inlet in communication with the cavity, and a porous diffuser plate extending across the outlet opening, the porous diffuser plate including apertures for the plurality of nozzles and a plurality of pores, where a shield gas passes through the shield gas inlet, through the cavity, and through the plurality of pores of the porous diffuser plate around the plurality of nozzles.

Abatement systems including an oxidizer head assembly and methods for using the same

A method for the pregobbing of an optical fiber preform to provide pre-optimized tip taper and system for drawing optical fiber therefrom. The downtime of an optical fiber drawing apparatus can be considerably shortened, by providing preforms that have a pre-optimized tip shape. Pre-optimized tips are provided which are melted off at the tip by an induction heater of a heating furnace. Preferably, the pregobbing furnace has substantially the same temperature profile as the draw furnace. Therefore, because the tip of the preform is optimized and unusable glass has been removed, throughput of the draw apparatus is advantageously increased. Moreover, the shape of the tip of the preform is optimized in that it has been exposed to the same temperature profile as it would have seen had the draw tip been formed in the draw furnace.

A method for threading a lead end of a fiber through the drawing apparatus of a fiber draw process. A prethread filament is fed through the apparatus of a draw process. One end of the prethread filament is then attached to the lead end of the fiber and used to pull the fiber through the apparatus of the draw process.
