Or just… longer cables. Ethernet is already designed for long cable runs, and USB and video cables are easy to find in lengths over 10m (though good ones are a bit pricey). You could even make do with standard cables if you set up against an interior wall and pass cables through the wall to the PC in the adjacent room.
Absolutely true, there are some real world scenarios where fiber has the advantage
- Low/No electromagnetic interference
-
- Radio labs
-
- MRI techs
-
- (audiophiles? maybe)
- Low latency, long distance
-
- The source computer can me many meters/km away
- All in one device
-
- One fiber pair can run the full KVM stack for a remote computer
But yeah, for most scenarios, conventional cables are fine, —
