Abstract
A visibly distinguishable colored optical fiber ribbon is provided having optical fibers with a colored secondary coating and an ink coating applied to the secondary coating. The optical fiber ribbons are also provided with a plurality of optical fibers therein, wherein each optical fiber has a uniquely colored secondary coating covered by an ink coating having a same color over a majority of the colored optical fibers. Since the optical fibers are distinguishable by color coding, the ribbon coatings do not require print identifiers thereon. As a result, the ribbons are easily identified in the dark enclosures where fiber optic cables are typically deployed.
