Wireless Router with 10Gbps Ethernet Passthrough

Hello r/networking!

I'm working on a project that involves a 10Gbps Fiber Optic tether between a control station and a robot. On the control station side, I convert from ethernet to SFP+, then use an SFP+ Fiber transceiver to send it down the fiber optic line, then do the reverse process on the other side. If all we needed was the tether, I would just plug the ethernet cable on the robot side into a 10Gbps switch, connect all the devices onboard the robot to that switch, and assign static IPs to everything.

Here's the complexity: I'd like to have the ability to drop down a wireless network for situations when the tether is not suitable. The idea is to plug the ethernet cable from the SFP+ -> Ethernet converter on the robot side into a wireless router, then connect the wireless router to the 10Gbps switch I mentioned above. In this case, everything would work exactly as I described above, just with a router in the middle. Then, when wireless was needed, the robot could disconnect the cable from router to switch and place the router offboard. It could then connect via a wireless client and passe the signal into the same switch I mentioned above. When the need for untethered operation completed, it would pick the router back up and reconnect everything to restore maximium speeds of 10Gbps (obviously 10Gbps will not be achieved over the wireless link).

The problem is that I can't seem to find a wireless router that has TWO 10Gbps ethernet ports as I need. I have looked into the Ubiquiti XG AP, which has a single 10Gbps Ethernet port and a single 1Gbps Ethernet port. This is not sufficient, as it would limit our tethered speeds to 1Gbps. Are there any products out there that can do what I'm describing? Or am I completely off in how this whole thing would work?

Thanks!
