Optical DIO?

I think this is a long shot ...

Does anyone know if someone makes an optical digital IO card?

By this I mean something with the same function as a regular digital IO card, but with optical transceivers rather than regular digital IO lines.

Thanks!

Stepping back a little - does it need to be optical, or does it need to be isolated?

Unfortunately it has to be optical. The UUT has fiberoptic transceivers which are controlled by an FPGA, which impliments a completely custom Manchester encoded data signal. If necessary, I'll design a small fiber-optic interface card which I can control with a DIO card. But I would rather not re-invent something that might already exist.

Ohhhhhhhhhh - so you actually want to control/measure pulses of light... Sorry - I don't know of any. I have done some work in that area a long time ago, and we designed an ad-hoc interface of light sensors.
