Beschreibung
Zusammenfassung:	1. A method of manufacturing optical waveguides, in which compact glass layers are produced directly on the inside of a substrate tube from a reactive gas mixture by electron impact initiation without sintering, characterized in that during the overall duration of the manufacture of glass layers a volatile hydrogen-free fluorine compound is added to the mixture of the reaction gases, both during the deposition of any adjusting or optical cladding layers and during the deposition of core material.
