Abstract
Apparatus for heating a silica optical fiber in a fiber-drawing installation. The apparatus is disposed at the outlet of a fiber-drawing oven to raise the optical fiber to a temperature greater than 1000.degree. C. The apparatus is constituted by a microwave generator coupled to a resonant cavity formed by a helically-wound metal wire helix fixed at opposite ends to two short circuit metal plates respectively, with the optical fiber running substantially along the axis of the helix and the helix concentric about the running fiber.
