Similarly, is optical audio better?
Both HDMI and optical pass digital audio from one device to another. Both are better than analog (the red and white cables). Both can pass multi-channel audio, like Dolby Digital. Both cables can be had pretty cheap.
Subsequently, question is, how long can you run an optical audio cable? A: The ADAT spec puts the limit on optical cable length at five meters (around 16 feet). However, the length you can achieve depends greatly on the cables you are using. Inexpensive optical cables lose signal quite rapidly. But good-quality glass cables can be used for much longer runs.
Accordingly, how do I know if my optical cable is working?
An optical audio cable should have a red light at each of the connectors when it's in place and working correctly. If you don't see the light at either of the ends, the cable isn't connected properly, is broken, or you might just have a faulty cable.
Does Optical Cable carry audio and video?
What it does: An Optical cable transmits digital audio signals as pulses of light. Like coaxial (below), it's surround-sound-capable for up to 5.1 channels of sound, but can't carry the high-resolution audio formats found on Blu-ray discs. However, it's still important to look for a well-made cable.
