Toslink

TOSLINK

TOSLINK (from "Toshiba Link") is a standardized optical fiber connection system. Also known generically as an "optical audio cable", its most common use is in consumer audio equipment (via a "digital optical" socket), where it carries a digital audio stream from components such as CD and DVD players, DAT recorders, computers, and modern video game consoles, to an AV receiver that can decode two channels of uncompressed lossless PCM audio or compressed 5.1/7.1 surround sound such as Dolby Digital Plus or DTS-HD High Resolution Audio. But, TOSLINK does not have the capacity to carry the uncompressed data in the lossless formats of Dolby TrueHD and DTS-HD Master Audio – as HDMI does.
