OPTICAL FIBRE WITH MECHANICALLY REINFORCED COATING

摘要

Optical fibre comprising a glass portion and at least one coating of crosslinked polymer material surrounding said glass portion, said coating being obtained by crosslinking a mixture comprising: at least one crosslinkable liquid composition comprising at least one oligomer containing at least one reactive functional group, at least one diluent monomer capable of reacting with said reactive functional group and at least one photo-initiator; at least one inorganic material with lamellar structure formed by a plurality of lamellae that have been surface-treated beforehand with a compatibilizer; characterized in that said coating is formed by said crosslinked liquid composition intercalated between the lamellae of said inorganic material. Preferably, said coating is a secondary coating or, in the case of a ribbon of optical fibres, it is a common polymer coating known as a "common coating".
