TOSLINK (from ''Toshiba Link''〔(Toshiba TOTX1701 ) TOSLINK Transmitter Module specifications.〕) is a standardized optical fiber connection system.〔("What Is TOSLINK?" ) Toshiba Toslink FAQs.〕 Also known generically as an "optical audio cable" or just "optical 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 surround sound such as Dolby Digital Plus or DTS-HD High Resolution Audio. Unlike HDMI, TOSLINK does not have the bandwidth to carry the lossless versions of Dolby TrueHD, DTS-HD Master Audio and LPCM. Although TOSLINK supports several different media formats and physical standards, digital audio connections using the rectangular EIAJ/JEITA RC-5720 (also CP-1201 and JIS C5974-1993 F05) connector are by far the most common.〔 100621 digikey.com〕 The optical signal is a red light with a peak wavelength of 〔 Depending on the type of modulated signal being carried, other optical wavelengths may be present.〔 A less common format is a coaxial cable ending in RCA jacks, which is found on some receivers. == History == Toshiba originally created TOSLINK to connect their CD players to the receivers they manufactured, for PCM audio streams. The software layer is based on the "Sony Philips Digital Interconnect Format" (S/PDIF), while the hardware layer utilizes a fiber optic transmission system, rather than the electrical (copper) hardware layer of S/PDIF. TOSLINK was soon adopted by manufacturers of most CD players. It can often be found on video source (DVD and Blu-ray players, cable boxes and game consoles) to connect the digital audio stream to Dolby Digital/DTS decoders. The name is a registered trademark of Toshiba, created from ''TOShiba-LINK''. Variations of the name, such as ''TOSlink'', ''TosLink'', and ''Tos-link'', are also seen, while the official generic name for the standard is ''EIAJ optical''. ADAT Lightpipe or simply ADAT Optical uses an optical transmission system similar to TOSLINK, and is used in the professional music/audio industry. While the ADAT Lightpipe format uses the same JIS F05 connectors as TOSLINK, the ADAT Lightpipe data format is not compatible with S/PDIF. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TOSLINK」の詳細全文を読む スポンサード リンク
