context_page_description: TOSLINK is a standardized optical fiber connector system. Also known generically as optical audio, its most common use is in consumer audio equipment, 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 or DTS Surround System. Unlike HDMI, TOSLINK does not have the bandwidth to carry the lossless versions of Dolby TrueHD, DTS-HD Master Audio, or more than two channels of PCM audio.
  Although TOSLINK supports several different media formats and physical standards, digital audio connections using the rectangular EIAJ/JEITA RC-5720 connector are by far the most common. The optical signal is a red light with a peak wavelength of 650 nm. Depending on the type of modulated signal being carried, other optical wavelengths may be present.
context_section_description: Mini-TOSLINK is a standardized optical fiber connector smaller than the standard square TOSLINK connector commonly used in larger consumer audio equipment. The plug is almost the same size and shape as the ubiquitous 3.5 mm stereo minijack. Adapters are available to connect a full-size TOSLINK plug to a mini-TOSLINK socket. Combined 3.5 mm jack and mini-TOSLINK sockets exist which can accept a 3.5 mm jack or a mini-TOSLINK plug; mini-TOSLINK plugs are made 0.5 mm longer than electrical jack plugs so that the latter are too short to touch and damage the LED of combined connectors. Many laptop computer and portable digital audio equipment models, such as the Google Chromecast Audio device and Apple AirPort Express and iPod Hi-Fi, use these connectors that allow for the insertion of 3.5 mm analog (electrical) headphone output or microphone input or mini-TOSLINK digital (optical) output.
