The laser pointer communication project has made me think. What would happen if instead of a laser, you concentrated a high intensity led into a fiber optic strand and passed the captured light through a prism. Would the modulated sound be split in anyway or would all the colours share the same sound.

Similarily, would it be possible to use 7 different light sources each with a different coloured filter, ROYGBIV. Transmiting that light from all seven light sources over one fiber, then have the recieving side use a prism to split the light back into each coloured 'channel' and recieving the same data as sent by the sender.

I'll most likely attempt this, I just can't find any time any more.

Do a Google search for "wavelength division multiplexing", and
"frequency division multiplexing". They are the same idea, just
different phrases.
