<p>An optical fiber (20) which includes at least one coating layer is provided with a color identification system which is nonpigmented. In a preferred embodiment, the optical fiber includes two layers (26,28) of coating materials. Applied over the outer one (28) of the two coating layers is a color identification layer (30). The color identification layer may comprise an oligomeric composition of matter and a polymeric dye. For those instances when relatively high hiding power is required, such as when optical fiber has been provided with a hermetic coating, the color identification system also includes an opacifier. In an alternative embodiment, the outer or secondary coating layer is a composition of matter which comprises the opacifier and the polymeric dye. <IMAGE></p> |
