The invention relates to a method of manufacturing an optical conductor, in which method, a mixture of a resin and of a photo-initiator is exposed to UV radiation in order to form, by cross-linking, the covering of the optical conductor. The cross-linking takes place by causing the conductor (,) to advance past a UV source at a speed of at least 10 meters per minute (m/min). The invention provides a first source (,) which emits monochromatic UV radiation to achieve cross-linking mainly on the surface, and a second UV source which emits UV radiation of broad spectrum containing wavelengths that are longer than the wavelength of the monochromatic source to achieve cross-linking mainly in depth.

Method for making an optical conductor

An optical fiber cable constituted by a single tube defining an internal bore housing at least one optical fiber and whose wall incorporates a reinforcement zone. The reinforcement zone is constituted by a thermoplastic material giving the cable both flexibility and resistance against compression and impact.

To color code optical fibers, a ultraviolet light curable ink is mixed with a carrier fluid. The mixture is then applied to a horizontally moving optical fiber by an ink applicator using a rigid applicator die. The fiber then passes through a convection oven to evaporate the carrier fluid and a ultraviolet light radiator to cure the ultraviolet light curable ink.
