TOSLINK® otherwise known as optical cable is a fiber optic connection system. Carries an audio stream from CD/DVD/Blu-Ray players and modern video games consoles to an AV receiver that can decode the audio and replay the output through loudspeakers.
As a result of its fibre optic make up it is undeterred by electrical or magnetic interference that can affect electrical cable alternatives. This results in a purer sound that is truer to the original recording. Gold plated for anti-corrosive properties.
