Suitable for digital fiber optic cable used to transmit digital audio signals of the media, unlike the conventional copper wire as conductor of the signal connection, vulnerable to the surrounding electromagnetic interference, fiber-optic lines that transmit high-quality and clear sound is unmatched by traditional wires, especially the transmission of digital signals via digital decoders for 5.1 channel audio distribution, and thus form a ring field of audio, digital optical fiber is also used for other high quality recording the best way.
