  • Optical fiber and method of manufacturing an optical fiber
    Patent number: 7630611
    Abstract: The present invention relates to a method of manufacturing an optical fiber by carrying out one or more chemical vapor deposition reactions in a substrate tube, with the optical fiber exhibiting a low sensitivity to the hydrogen-induced attenuation losses at a transmission wavelength of 1550 nm. The present invention furthermore relates to an optical fiber comprising a cladding layer and a light-conducting core, which fiber has been obtained by using the present method.
    Type: Grant

  • Method of manufacturing an optical fibre
    Patent number: 5320660
    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.
