i like toslink because its entire reason for existing is "hey optical fiber is cool, let's use it for this thing even though it's the 90s and we don't have the technology to do it well yet"
its purpose could easily be filled by a copper cable but optical fiber is Cool™er
it's not very good optical fiber which means it's cheap, too
@Felthry the only thing it does that you can’t with copper is isolation.
But yeah, it can even be very long or the modal dispersion gets too bad and the photodiode can’t register on and off

@roguecnidarian oh you can do isolation with copper too, just stick a transformer or a capacitive isolator in there somewhere
