A coaxial digital audio cable uses copper wiring as its signal conductor and dual-RCA jacks as connectors. An optical digital audio cable uses fiber optic wiring as its conductor and dual Toslink connectors. Both types of cables perform the same function; however, an optical digital audio cable is immune to external interference because its conductor is non-metallic.
