A type of fiber-optic cable connection that uses beams of light to transfer information through a clear plastic cable. This is similar to the AT&T ST fiber-optic cable except that the AT&T technology uses glass strands to transmit the information and is generally considered a superior fiber-optic format (although it is more expensive and harder to find). oslink cables use light beams to transmit digital information from digital audio components. They are fairly common on mid- to high-end CD players, DVD players and laserdisc players. Most all digital-to-analog converters and digital surround sound processors (Dolby Digital and DTS processors) can connect to source components using Toslink cables and connectors. Using light beams to transmit digital information avoids potential interference from electrical wiring and other electrical devices that can interfere with traditional metal cables carrying electrical signals.
