For now it is just to control lighting. I want to try it on some other things in the future though. What i want is a PCI card for my PC that has a fibreoptic output. I want a fibre optic input on a box im making. That box will then have outputs for serial and other things.

This whole thing could be done easily with USB i think but i want to test out both fibre optics and custom PCI cards. For now i would be happy just converting serial/USB to fibre. From what i can tell it looks like fibre optic works the same as an opto isolator. Ive seen serial devices protected with an optoisolator before so i assume its as simple as putting the fibre transmitter/receiver in its place.

I also want to experiment by using my own protocols to see how fast i can get the data through the fibre.
