Toslink cables transfer audio signals as a standardised optical fibre connection system. They are suitable for Hi-Fi end devices, televisions, home cinema systems, sound bars and games consoles. They are barely sensitive to electromagnetic interferences caused by other devices. They can transfer stereo sound, which is very common, and other sound formats such as DTS and Dolby Digital. As optical fibres are particularly sensitive, the cables are equipped with sturdy sheathing.
