Abstract
In accordance with the invention, an optical fiber is provided with a protective polymer coating that is substantially free (less than 0.1% by weight and preferably 0%) of adhesion promoters and coupling agents. Advantageously, in lieu of adhesion promoters, the primary polymer coating formulation is provided with an additive which will covalently bond with the fiber but not with the primary polymer.
Claims14
An optical fiber coated with a radiation-cured primary coating, the optical fiber comprising an elongated strand of glass that is adapted to guide light waves along the length, the primary coating comprising a primary polymeric material and a photoinitiator
- CHARACTERIZED IN THAT
- the primary coating is substantially free of adhesion promoters or coupling agents to enhance delamination resistance and thermally enhanced strippability, the proportion of adhesion promoters and coupling agents in the primary coating less than 0.1 weight %.
An optical fiber coated with a radiation-cured primary coating, the optical fiber comprising an elongated strand of glass that is adapted to guide light waves along its length, the primary coating substantially free of adhesion promoters and coupling agents and comprising an additive which covalently bonds with the fiber but not with the primary polymer.
