| Zusammenfassung: | A vapor-phase axial deposition system for fabricating, by means of a torch (112) generated soot stream (18), a glass preform (302) for use in optical fiber production. A novel torch (112) is provided having a position adjustable inner tubing allowing simple adjustments of the torch during the fabrication process. Also, the configuration of the deposition chamber (10) and the exhaust system are arranged so as to minimize turbulent flow of the various gases within the chamber to minimize flicker of the torch flame. This results in a more reproducible deposition process. |
