I wanted to share this opinion on Hackaday about a topic that is the usefulness of a something that has become ubiquitous relatively fast.
This techonolgyy has a lot of potential, what do you think?

In general, you don’t want DC or Ethernet cabling directly next to AC wiring. I forget the exact rules and distances, but you definitely don’t want them in the same conduit at least. Shielding only helps so much. Just a general note as you probably didn’t mean it quite so literally…
I do like PoE though! I have a server rack that powers a bunch of RPi 4s through a PoE+ switch. Had to make sure there was plenty of headroom as RPi 4s can pull just a wee bit of current under full load. I am just happy it works at all.
It’s running parallel to AC wiring. It’s usually not a big deal in practice, except for higher draw cable.
Your right. I was thinking about my job that runs 480VAC. Either way, testing for interference and noise when you run into issues can go a long way. I am just glad that, to my knowledge, CAT 7 is one standard with everything shielded. CAT 6 had so many variations and most packaging and online portals would not even tell you which ones they were using in the first place. Almost as bad as USB-C connectors.I gave up and ordered some short CAT 7 patch cables for the server so I wouldn’t stress over it. Ended up being a little cheaper than a lot of the cat 6 sets too.
