I always forget the speed differences (and other specs) for ethernet cables. I can find what I need from various sources, but I haven’t been able to find a good chart with the info I want to print out at work. Most likely I’ll create my own, but I’m curious what’s already out there.

Looks like we’re up to CAT8 now, with limit of 30meters, whereas CAT7 and lower are all 100m at their base speeds. Here’s my basic cheatsheet:

CAT5 - 100Mbps, 100 Mhz

5e - 1Gbps

6 - 1Gbps (10Gbps < 55meters), 250 Mhz

6a - 10Gbps, 500 Mhz
