I have never seen such a thing, while working with optical for a long time. The optical signals would "freak" each other out and nothing would come out. They need to be discrete and can be switched, but can't be combined.

...but this is something you can use if you don't mind the switch.

If you need one let me know, I sell all of their stuff!

Someone else may even make one that is IR compatible.


Hope this helps.
