They carry the exact same data, they just have different physical interfaces. Both interfaces are referred to as S/PDIF (Sony/Philips Digital InterFace). If you have both on a device, they are typically wired in parallel. Because they are so different physically, they each have some advantages over the other. Here are some differences between them, with "+" being an advantage and "-" being a disadvantage:Digital Coax
+ It will work with standard audio/video cables .
+ It can be run a longer distance than optical, and supports many connections along the way.
- It can sometimes cause ground-loops between equipment, typically causing hum and/or no audio down the coax.
+ It will not cause ground loops.
+ It is immune to electrical noise.
- The signal doesn't survive long runs, or more than a couple of connections.
It is often said that Toslink can contain more clock-jitter than coax, but that is not necessarily true. Even if it were true, current architectures make it no longer relevant.
There may be other differences that I can't remember right now.
