Fibre having a protection coating and method for its production

Abstract

Abstract The covering includes a layer formed by an oligomer of cross-linked polydiene epoxide (9). An Independent claim is included for the method of fabrication of the fiber and covering described. Preferred features: The layer is 20-60 mu m, preferably 20-40 mu m thick. The fiber is a silica or plastic optical fiber, including an optical waveguide (1). Between the oligomer and the fiber there is a layer (11) of cross-linked material, adhering less with the fiber than the oligomer and compatible with it. It is UV-cross linked and is 10-100 mu m thick, preferably 20-60 mu m thick. The protective covering (7) is marked with color. The color is incorporated in the oligomer layer (9). Coloring and UV protection variants are described. A variant optical fiber is described. A cable based on a single fiber, or multiple fibers, is described.
