   rj45 is such a funny connector if you think about it. it was designed for telephone switching in the 70s and 80s and it actually is fairly reasonably designed for a telephone signal connector. But it became used for Ethernet, and more Ethernet, and faster signals, and now we're able to send 10gbps down this little 8 pin jack from the 70s, and I'm surprised that it still works for this purpose

     It works for short runs. I have some 10Gbe on copper/CAT6 on my Proxmox cluster, but they're all under 1ft. I can usually get 8Gb~9Gb on iperf. But for linking upstaris/downstairs, I use fiber .. it can reliably always get over 9Gb

     Like, I guess if you were to imagine a 10gbit connector you'd think it would be something more ... coaxy ... but no, 10gbit works totally fine over shielded twisted pairs

     100gbit is something that 70s engineers could only dream of the entire world's throughput being, and yet we can achieve it with 10 Cat6 cables
