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
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
@rail_ oh that's an interesting article, I'll take a read later!
Skimming it, they mention that Ethernet is totally uncoordinated between the N halves and it's literally just spray frames and back off if you collided, and yeah that's another feature that is really funny about Ethernet
