Abstract

Bei einem bekannten Verfahren zur Herstellung einer Vorform für optische Fasern wird ein mit Fluor dotiertes Si02-Mantelglases auf einem um seine Längsachse rotierenden Kernglaszylinder erzeugt, indem einem Plasmabrenner eine siliziumhaltige Ausgangssubstanz zugeführt wird, diese in einer dem Plasmabrenner zugeordneten Plasmaflamme zu Si02-Partikeln oxidiert und die Si02-Partikel unter Gegenwart von Fluor auf der Zylindermantelfläche des Kernglaszylinders schichtweise abgeschieden und zu dem Mantelglas gesintert werden. Um hiervon ausgehend ein wirtschaftliches Verfahren zur Herstellung einer Vorform bereitzustellen, aus der optische Multimodefasern (52) erhalten werden können, die sich gegenüber den nach dem Standardverfahren hergestellten Fasern (51) durch hohe Anfangstransmission im UV-Wellenlängenbereich und guter Beständigkeit gegenüber kurzweiliger UVStrahlung, insbesondere im Wellenlängenbereich zwischen 210 und 300 nm, auszeichnen, wird erfindungsgemäss vorgeschlagen, dass zur Bildung und Abscheidung der Si02-Partikel auf dem Kernglaszylinder eine Plasmaflamme eingesetzt wird, die ultraviolettes Licht einer Wellenlänge von 214 nm mit einer Intensität von mindestens 0,9 µW - ermittelt anhand der Plasmaflammenintensitätsmessung - abstrahlt.
