For those curious I found this website (http://pofto.com/) which was very helpful. Unfortunately finding the connectors etc. is still a bit difficult. Most of the integrated packages are designed for low speed (5-8mbps). Slightly higher speed connectors do exist (13-25mps). Thus if you want anything faster than the standard Toshiba TOSlink you likely will have to roll your own. It's possible to use the optical 1394 http://www.firecomms.com/ has information on high speed data links using there optical devices. However no complete standard subassemblies just the Transmitter and Receiver elements that can be integrated into them (yeah more expense!) Side note optical communication appears to have a lot of interesting challenges associated with it. One of which is keeping things synchronise over a distance if you have some sort of need for precise data rate exchange (not terribly important for my application). I hope this helps other people looking for similar information. __________________________________ Do you Yahoo!? Yahoo!
