Abstract

A drawn glass element for producing glass optical waveguides is provided. The element has two first length portions with a first cross-sectional area and which define the two ends of the glass element; a second, intermediate length portion between the two first length portions, which has a second cross-sectional area smaller than the first cross-sectional area; a first transition portion between the intermediate length portion and one of the first length portions; and a second transition portion between the intermediate length portion and another of the first length portions. The first and second transition portions have a cross-sectional area that steadily changes and merges from the first cross-sectional area into the second cross-sectional area.
