Abstract
A color-coded optical fiber ribbon includes a plurality of substantially parallel, adjacent, longitudinally extending optical fibers disposed, at least at a given cross section of the optical fiber ribbon, in substantially the same plane. A resin matrix material covers the optical fibers, which have at least one coating formed thereon. A color-coding identification scheme for the optical fiber ribbon is formed by coloring the optical fiber ribbon with at least two colors. A ribbon die for producing the color-coded optical fiber ribbon includes at least one coating chamber having at least one primary coating orifice for supplying a primary coating material to be applied to the optical fibers; and at least one flow guide channel for supplying a colored material in addition to the primary coating material in order to coat predetermined areas of the fiber optic ribbon so as to form the color-coding identification scheme.
