Our Toslink Optical Digital Cable is made from medical-grade light-conducting fiber. This premium material has excellent light-transfer characteristics, and will not microscopically fracture when the cable is bent or flexed. Our cable is incredibly flexible, making it great for snaking through tight spots in custom installations or crowded equipment racks. The cable body 8-mm thick. The metal-body Toslink connector at each end helps block EMI/EMC interference for maximum signal integrity.
