What would this card do ? I assume by looking at your website you want to trigger lighting using the PCI card in a PC, and have the unit have opto isolated outputs ?

It might be better to find a generic PC multioutput PCI card like the one shown here : http://www.web-tronics.com/64isdigoutca.html - 64 channel
http://www.web-tronics.com/32isdigoutca.html - 32 channel

Or do you mean a serial output card with a fibre optic output port?

With more information you might get some more help.
