@romanesq So what's the difference between the Finisar you are using and something like this:

For someone like me who is not tech savvy, the DX Engineering looks like an easier fix, although I see it's not optical. IOW, what, besides the cabling, do you need to add to the Finisar? How is it powered? Does it need an enclosure, or you just run them naked?
