Oh, I guess those 44 guage, ridiculously tiny wires are exactly the same as a couple of 12 guage wires? Why doesn’t the power company just use ethernet to bring power to your home? Why don’t electricians wire the house using ethernet instead of romex? LOL… There is some physics behind the transfer of power/signals along a metallic conductor, and it involves the surface area which is where all the signals (whether they be your internet porn, power to a light, or your Steel Magnolias soundtrack) actually move by electron displacement along the outermost layer of copper.
BUT, for the purposes of these magical transmogrifiers of the internet(s) into electricity we can reach by plugging in the collusionary receiver… the fact remains that you have a signal traveling along 8 tiny copper wires… then 2 bigger wires… then 8 tiny ones again. So your porn flows from modem to your upstairs bedroom, un-converted.
If you are remotely curious, I’d suggest a physics class to learn in more detail, including some cool formulas that explain all this magic.
I wish I had donald trump’s hands, because I can relate to wiring TINY ethernet jacks. I just put cat 6 and fiber all throughout my home. 32 ethernet keystone jacks to wire. And 32 terminal ends to wire. Small hands would have been… well, um, handy…
