Toshiba originally created TOSLINK to connect their CD players to their own brand receivers. As time passed, it ended up becoming a popular format for digital audio output from some devices - but mostly from TVs to receivers. If your newer TV does not have an HDMI out to go to your receiver, then you use the Toslink digital optical cable out to do as much just for the audio. This format does not carry any video. FireFold provides you with a variety of cable thicknesses and lengths in the Toslink digital optical cable line to allow you to find the perfect one for you.
