Beginner question here but I have yet to find the answer anywhere online (yet).
I recently came across a website (True Cable Dot Com) that claims their keystone connectors have circuitry (“secret sauce” as they call it) that impedance matches ethernet cable runs. I’ve been digging around online and can’t find anything regarding impedance matching in ethernet cables. I find it regarding coax but not ethernet.
I suspect that the answer is no due to the lack of info online but I haven’t found a definitive answer so far.
So, I’m asking here. Is impedance matching in ethernet cables a thing or not?
Yes there is. It’s measured as part of the return loss when installing and certifying commercial cabling.
Unless you are a professional installer you don’t need to test for it as the tester is mega bucks. For SOHO just use good quality cable and keystones. No gimmicks required. Only tool for home install I would get is a very basic continuity tester that just checks you have terminated all the connections and not got any crossed over.

Thank you for the info. That is what I kinda figured. I wired my entire house with CAT6 cable without keystones or RJ45 plugs that had “Special circuitry” for impedance matching. I did use a continuity and cable tester for all the runs. The runs are all less than 120ft. I have 1G fiber internet coming in and am getting consistent 950Mbps throughout the network. Like I told Willie on our last call, I probably won’t upgrade my speeds as 1g seems to be plenty for my needs right now and anything higher would be only useful for bragging rights.
Thanks again.
