Abstract
An optical fiber having an ink layer that includes an optical brightener is described. The optical brightener is a marker that permits identification of the fiber. The ink layer may also include a pigment, where either or both of the pigment and optical brightener may function as a marker for identifying the fiber. Bundles of two or more optical fibers, each of which includes an ink layer containing an optical brightener, are also described.
