Toslink is a connector format for fiber optic digital audio cables. A fiber optic digital audio cable carries audio data in the form of light impulses instead of electrical signals. The Toslink connector is a square plug and is used with newer Dolby Digital surround sound receivers, digital versatile discs (DVDs), and compact disk (CD) players, satellite dish receivers, and other devices. Miniplug is another fiber optic digital audio format, similar to Toslink, used for minidisk players and other smaller digital audio devices. There are adapters available to convert a Toslink plug into a miniplug.
