Abstract
An optical fiber having a circular outer cross-section and having a core which has a noncircular cross-section is produced by using a double crucible. The outer crucible is provided with a ring-shaped channel of which at least one of the boundary walls has a noncircular cross-section. The glass of the outer crucible is passed through this channel before it is contacted with the glass of the inner crucible.
