I created a cheat sheet for Ethernet, when I built my home network: https://github.com/ProZsolt/runbook/blob/master/ethernet-cab...

Really nice !

Today I learn that there is a 25 and 40G-BASE-T on copper, these PHY must heat like hell haha.

shoud 100, 400, 800G be added, yes a bit earlier for 800G but I think 100/400G are already in use at data centers.

This only covers twisted pair, as I only use this as reference when I need new endpoints in my or my parents house.

I'll update the guide when I rewire my house with fiber optics (currently I don't even use the full potential of cat 6), but contributions are welcomed.
