Default Q: How long can I run a digital line?

OK, use it because it's better then. Until amplifiers and players
have lightpipes instead of wire inside, there's going to be a
conversion from electrical signal to light and a conversion back at
the other end. This isn't going to INCREASE quality, is it.


Not likely to decrease it either, is it?

buit the optic fibre isnt going to transmit electrical noise is it?


Sure. It'll transmit whatever you feed it. Hopefully :-)

You mean "pick up", not "transmit" of course.

Digital signals are relatively immune to noise. What they DO suffer
from is clock jitter and waveform corruption of various kinds, I
think.
