Abstract
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 (3) of the coating (4) which interfaces with a cladding section (2) to the external surface of the coating (4). 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 an optical fiber, comprising at least one partly crosslinked polymer, characterized in that a level of crosslinking increases according to a radial distance from an internal surface (3) of the coating (4) which interfaces with a cladding section (2) to an external surface of the coating (4).
A method of manufacturing of a coated optical fiber comprising the steps of drawing of the fiber, deposition of a coating (4), cure of the coating (4) and spooling of the optical fiber, characterized in that the coating (4) comprises a single resin composed of a volatile, multifunctional and moderately reactive monomer dissolved in a fast curable oligomer, having a low modulus when polymerized and in that said monomer is not completely cured.
