Abstract
A method and apparatus for distinguishing various fiber-optic cables from each other in an installation where cables are grouped together, the apparatus comprising a light source for generating a high-intensity, reasonably highly collated, colored, and pulsed light beam. The light is coupled into one end of a fiber-optic cable, whereby an installer can easily observe the corresponding light coming out of the opposite end of the cable to distinguish that cable from the other cables.
