A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

You can run 10gbps over wire coat hangers, if the connection is short enough and external factors are small enough. The longer it is and the more interference, the less likely that becomes.
It looks like generally speaking, 37-55 meters (120-180 feet) is the common limit where this becomes infeasible. Will it work beyond that? Maybe. Or maybe it'll work some of the time. Or it'll always say 10G, but you get a lot of lost packets.
If you're wiring new, go Cat6a. Better yet, run conduit. That way you can easily run cat6a now, and later replace it with cat8 or fiber or whatever becomes the standard.
