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 T(R)S connector. 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 or mini-TOSLINK plug; mini-TOSLINK plugs and sockets are made 0.5 mm longer than electrical jack plugs so that the latter are too short to touch and damage the LED of a mini-TOSLINK capable socket. Generically known as optical audio, the most common use of the TOSLINK optical fiber connector is in consumer audio equipment in which the digital optical socket carries (transmits) a stream of digital audio signals from audio equipment (CD player, DVD player, Digital Audio Tape recorder, computer, video game console) to an AV receiver that can decode two channels of uncompressed, pulse-code modulated (PCM) audio; or decode compressed 5.1 or 7.1 surround sound audio signals, such as Dolby Digital and DTS. Optical cables have galvanic isolation, thus are not susceptible to electrical problems such as ground loops, RF interference, ESD events. Several types of fiber can be used for TOSLINK: inexpensive 1 mm plastic optical fiber, higher-quality multistrand plastic optical fibers, or quartz glass optical fibers, depending on the desired bandwidth and application. Many discontinued laptop computer and portable digital audio equipment models, such as the Google Chromecast Audio device, Apple AirPort Express, and iPod Hi-Fi, as well as some MiniDisc recorders, use these connectors that allow for the insertion of 3.5 mm analog (electrical) headphone output, microphone input, or mini-TOSLINK digital (optical) output (or input, in the case of MiniDisc recorders). 1 2 3 4 "SPDIF".

Everything You Need to Know About Using an Optical Audio Port for ...

ascentoptics.com

Also referred to as TOSLINK or SPDIF ports, optical audio ports have become a standard procedure in all current sound systems to make transmitting high-quality A: An optical output is a type of port for transmitting audio and sound from one device to another device. It does that by utilizing a TOSLINK port. This is similar to a 3.5mm jack, except that instead of sending an audio wave through a cable, it sends light pulses representing audio signals. A: Apart from the fact that the Chromecast audio used to have an optical output integrated to the 3.5mm jack, most audio output in streaming devices is today streamed through HDMI. Dolby Digital offers supplementary multi-channel audio encoding with a high compression ratio. This format enables the optical interface to carry as much as 5.1 discrete channels, making it more compatible and applicable to most home theatre systems. This format is widely used with optical audio thanks to its excellent surround sound capabilities.

What is a Digital Optical Connection?

www.lifewire.com

The digital optical connection was made to accommodate the digital audio standards of its time (mainly 2-channel CD playback). Thus, 5.1/7.1 multi-channel PCM, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, DTS:X, and Auro 3D Audio digital audio signals cannot be transferred via digital optical connections. Robert Silva has extensive experience in consumer electronics and home theater product sales and sales supervision; he has written about audio, video, and home theater topics since 1998. Robert has articles published on HBO.com and Dishinfo.com plus has made appearances on the YouTube series Home Theater Geeks. ... Digital audio connections use fiber optics and are found in some home theater systems and car stereos. The development and implementation of the digital optical (Toslink) connection paralleled the introduction of the CD audio format, where it was first used in high-end CD players before it expanded into home theaters. The types of digital audio signals that can be transferred via a digital optical connection include two-channel stereo PCM, Dolby Digital/Dolby Digital EX, DTS Digital Surround, and DTS ES surround sound formats.
