Abstract: A Hi-Fi audio signal optical fiber cable has an optical fiber bundle provided coaxially inside a snake tube. The optical fiber bundle has multiple optical fibers. Both ends of the optical fiber bundle protrude from the snake tube and are installed with a connector respectively. An air gap is formed between the optical fiber bundle and the snake tube so that ordinary air fills in the air gap. When a signal source inputs an optical signal via one connector, the optical signal is transmitted within each optical fiber by total reflection and goes out from the other connector. Since the refractive indices of the optical fiber bundle and the air have a significant difference, the total reflection is better, thereby achieving high fidelity. Each optical fiber has a smaller numerical aperture, and the optical path of the optical signal is shorter and signal attenuation in the material is avoided.
