Abstract
A fiber optical cable for conducting light along its length. The cable is composed of a plurality of transparent polymer fibers. The fibers are formed by drawing the heated viscous polymer from an orifice. In pulling the softened fiber, the polymer molecules become aligned parallel to the sides of the polymer fiber. A surface coating of a lower refractive index transparent polymer is applied. The optical fibers are arranged in the desired order and heated and softened. Pressure is applied against the sides of the heated and softened fiber optic cable compressing the round polymer optical fibers to form fibers having flat sided geometric shapes to eliminate the open spaces and voids between the optical fibers.
