Abstract
A composite optical cable for lateral emission of light flux therefrom includes a plural number of sets of transparent optical fibers with each set of fibers assembled into a single cable and with a plurality of single cables assembled in the composite optical cable. The sets of optical fibers forming the single cables may be wound in one direction of rotation to form a spiral of fibers with length, and the single cables may be wound in the opposite direction of rotation to provide the composite optical cable. Selected masking schemes provide apertures at predetermined locations along the single cables through which light flux carried by the cables may be emitted for special lighting effects.
