Luxtera has developed a technology that sends plain ol’ electrical signals over fiber optic cable. At IDF in San Francisco, the company showed off a way to take a Displayport signal and send it over fiber. When set up this way, you’d be able to send a monitor signal 10KM away. That’s probably not too useful for everyday use, but imagine being able to use some cheap fiber in an concert venue or some other large outdoor event where you’ve got giant monitors all over the place. I completely made up that scenario and have no idea if it’s feasible or not.
So, to recap: a Displayport signal that can be sent as far as 10KM. Neat-o.
