Most commonly used with audio equipment (via a &quot;digital optical&quot; socket) where it carries a digital audio stream from devices such as CD DVD Blu-Ray players and modern video game consoles to an AV receiver such as surround sound system that can decode the stream of audio and output it through a set of loudspeakers.&lt;br&gt;&lt;br&gt;Since TOSLINK uses fibre-optic cable it is free from distortion caused by electrical or magnetic interference that an electrical cable would incur.&lt;br&gt;&lt;br&gt;The result is an audio signal that is purer as well as truer to the original recording. Gold plating is used on the connectors for its anti-corrosive properties.&lt;br&gt;&lt;br&gt;- TOSLINK Optical Fibre&lt;br&gt;- Overall Diameter 5mm&lt;br&gt;- Black and Metallic Finish&lt;br&gt;&lt;br&gt;&lt;b&gt;Connection A&lt;/b&gt;&lt;br&gt;Digital Optical (M)&lt;br&gt;&lt;br&gt;&lt;b&gt;Connection B&lt;/b&gt;&lt;br&gt;Digital Optical (M)&lt;br&gt;&lt;br&gt;&lt;b&gt;Length&lt;/b&gt;&lt;br&gt;2m&lt;br&gt;&lt;br&gt;&lt;b&gt;Colour&lt;/b&gt;&lt;br&gt;Black&lt;br&gt;&lt;br&gt;&lt;b&gt;Packaging&lt;/b&gt;&lt;br&gt;OEM
