ABSTRACT:
An optical fibre is manufactured by stretching a rod-shaped initial preform, after which a cladding tube is melted on the initial preform and the final preform thus obtained is drawn into an optical fibre. A narrow and hot softening zone is used to stretch the initial preform, which softening zone is obtained, for example, by means of a plasma torch 2. By virtue thereof, the stretching process can be controlled in a rapid and simple manner.
