Corning Cable Remote Setup

[SeAzhrei]

I’m looking to get my pc out of the room and this seemed to be a way. I have a tb3 hub a couple metal tb3 short cables, and a Corning opt. tb3 cable. My test runs have not been successful.

I plug in and turn on the hub, plug in hdmi to hub and monitor, then plug the tb3 cable into my gpu and the hub input port.

If I use a short copper cable everything works fine. The hub light changes from green to blue indicating it sees my pc and my monitor instantly comes awake. 

If I use the Corning cable nothing happens at all. The hub light stays green and seemingly never even sees my pc. I’ve replaced the Corning cable as well to make sure it wasn’t a bad cable.

 

Am I missing something obvious here, or is this just not happening?

Does the hub get power from the thunderbolt 3 cable? If it does, the optical cable won't work.

Nope. Powered from the wall.

 

Don’t know what other info would be relevant. If there is anything just say so and I’ll get it. Currently working from a Remote Desktop connection on a tablet so everything’s a bit of a butt ache.
