    Abstract: A method of producing an optical fiber wire including a coating made of an ultraviolet curable resin, the method includes: a first irradiation step including applying first ultraviolet light to a point on the optical fiber wire where at least a portion of the ultraviolet curable resin is uncured; and a second irradiation step including applying second ultraviolet light to the point on the optical fiber wire where at least the portion is cured after the first irradiation step. The portion is a surface layer of the coating. A temperature of the optical fiber wire immediately before the second irradiation step is 50° C. or higher and 300° C. or lower.

    Abstract: A device for coating a fiber includes a fiber receiving arrangement and a coating arrangement which includes an application unit which wets the fiber with a coating agent, and a curing unit arranged downstream of the application unit which optically cures the coating agent. The curing unit includes a lamp which emits at least one light beam which is aimed directly or indirectly at a surface of the fiber. A main radiation direction of the lamp includes a beam angle between the main radiation direction and a longitudinal direction of the fiber of less than 40°. The fiber receiving arrangement and the application unit are movable relative to each other in the longitudinal direction of the fiber via a translational motion arrangement so that a wetting process is implemented substantially along an entire length of the fiber.

    Abstract: Disclosed herein are compositions for coating an optical fiber containing an optional reactive monomer and/or oligomer, a self-healing component with self-healing moieties, an initiator component, and optionally an additive component. The self-healing component preferably includes polymerizable moieties. Such compositions contain greater than 30% by weight of the self-healing component, and/or greater than 0.015 equivalents of self-healing moieties per 100 g of the composition. Also disclosed herein are coated optical fibers having a glass fiber, at least one coating layer and an optional ink layer, which are configured to possess self-healing properties and/or stress relaxation behavior. Further disclosed are methods for coating self-healing optical fibers, and optical fiber cables comprising a one or more self-healing coated optical fibers.
