Hi, Are there any cheap PCI>fibreoptic cards already out? If not how can i make one myself? Infact, how can i make one anyway? (I might have other uses for PCI)

By the looks of things the fibre optic bit is straight forward and should be just like using an optoisolator. Ive had a look on google and aparently any kind of PCI device is simple so does anyone know where to start?
