Method of production of a coating composition useful for covering glass fiber by means of a polymeric composition consisting of an aqueous suspension or emulsion of a polymer. The coating composition is deposited on the glass fiber and, next, the assembly is submitted to a curing process that is carried out at very high temperature and during a very short period of time.

Method of production of a coating composition

Coating for an optical fiber and method of manufacturing thereof, the coating comprising at least one partly crosslinked polymer having a level of crosslinking which increases according to a radial distance as one moves from the internal surface ( ) of the coating ( ) which interfaces with a cladding section ( ) to the external surface of the coating ( ). The coating comprises a single resin which is composed of a volatile, multifunctional and moderately reactive monomer dissolved in a fast curable oligomer, having a low modulus when polymerized.

Coating for optical fibers and method of manufacturing thereof

The filamentary elements are of a diameter that is less than or equal to 1 millimeter. The support comprises longitudinal channels each intended to house a respective filamentary element, each channel being defined by two longitudinal walls interconnected by a web and defining a longitudinal channel opening, the width of said longitudinal opening being variable by elastically deforming the longitudinal walls between an access configuration giving access to the channel enabling a filamentary element to pass through said opening and a retaining configuration for retaining a filamentary element in the channel. The filamentary elements are selected from optical fibers and electrical coaxial cables.
