The present invention relates to the preparation of an optical fiber in a form suitable for use in the manufacturing of a telecommunications cable having one or several fibers. The fiber is reinforced by a longitudinally disposed support element intended to bear at least a part of any traction forces which would otherwise be borne by the fiber.

Mechanical protection and reinforcement for optical fibers

The present invention relates to optical fibres with a protective covering for use in cables. The fibre is protected by a covering of plastic material extruded from an extruder the punch of which protrudes 0.5 to 1 mm beyond the draw plate, and rapidly cooled at the outlet of the draw plate, so that it surrounds the optical fibre with a clearance between 1 and 10 microns.
