Abstract: Present invention discloses a method of producing a local illumination patch cord and the corresponding patch cord, based on the technology of a multi-fiber optic cable, from the entrance of supplies till the final product—the local illumination patch cord. Among various available cables, none of those on which tests were carried out met the following final product requirements: flexibility, light efficiency, and decrease of factors affecting its resistance, namely the heat. In opposition to the current accessories available in the market, present invention decentralizes the thermal filter from the cable to the coupling, enabling heat dissipation before entering the illumination cable. Regarding the luminous efficiency, present invention defines a technique with a more effective manner of aggregating the multi-fibers of the cable, with significant savings in production times, and raises polishing quality to the highest level of light transmission.
