Digital fibre optic connections carry the advantage of not being distorted by electromagnetic influences.
The optical audio cable also decouples the audio transmitter/receiver and the audio receiver/amplifier and prevents the occurrence of "ground loops".
2 audio channels can be transferred via one digital audio cable as well as all the necessary audio channels for a home cinema system.
The audio channels are split in the amplifier, then amplified and passed on to all connected speakers.
With fibre optic cables, you must be sure that there are no bends in the cable; otherwise it may break.
