Abstract

Câble de fibres optiques comprenant un coeur de verre ou de silice dans une gaine transparente à plus bas indice de réfraction, elle-même entourée par une chemise. Entre la gaine et la chemise sont placées au moins deux fibres polymeres de renforcement ayant un module d'élasticité d'au moins 70 kg/mm**2, mises sous tension parallèlement au coeur avec une torsion pratiquement nulle. Application à la transmission de la lumière.Optical fiber cable comprising a glass or silica core in a transparent sheath with a lower refractive index, itself surrounded by a jacket. Between the sheath and the jacket are placed at least two polymeric reinforcing fibers having a modulus of elasticity of at least 70 kg / mm ** 2, tensioned parallel to the core with practically no twist. Application to the transmission of light.
