A method of coating an optical fiber includes a step of coating the fiber with a curable coating composition and a step of curing the composition, which contains an unsaturated compound having a double bond and an oxidation catalyst. The curing step includes an in-line first phase consisting in exposing the coated fiber to UV radiation for a time shorter than the time needed for complete curing followed by an off-line second phase consisting in placing the coated fiber in an oxidizing medium in order to complete curing.

Method of coating an optical fiber

A cable containing at least one optical fiber and at least one covering layer containing a material including an organic compound and an inorganic compound, wherein the inorganic compound has a layered structure and the organic compound is inserted between the layers of the inorganic compound.

Optical fiber cable having improved properties

In a thin conductor cable configured as a flat ribbon cable and surrounded by a common exterior sheath, the plurality of thin conductors are adhesively grouped together using an emulsion polymer.

Thin conductor ribbon

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.

Fluorinated diol and method for the production thereof

Polyurethane acrylate or vinyl type polymeric material for coating optical fibers based on a fluorinated diol

A method of coating an optical fiber, the method including at least one coating step using a coating composition and at least one polymerization step, the composition including a curable formulation and a compound having a low vaporization temperature, the quantity, by weight, of the compound having a low vaporization temperature lying in the range 0.5% to 20% of the composition, the vaporization temperature lying between the coating temperature and the polymerization temperature. The coating composition includes an acrylate resin and an ether, the quantity, by weight, of the ether lying in the range 0.5% to 20% of the composition. The ether can be an alkyl ether, in particular.
