Abstract
In a fiber optic cable having a plurality of optical ribbons, identifying information about each optical ribbon is conveyed by a series of colored regions of different colors visible on an outer surface of the optical ribbon matrix covering. In preferred embodiments of the present invention, the colored regions are formed in such a way that they do not cause microbending or the like. Preferably, the colored regions are formed during the process of extruding the matrix covering over the fibers, by injecting colored material into the extrusion die.
