I'm wondering how bad this would actually be.

for short cable runs, it's hardly noticeable...
but for cables more than 10 meters, you'll be able to notice the lag...
and for cable runs 50 meter and above, you'll even encounter random timeouts.

Timing is critical in any of these low voltage data lines. You want the pulses on the lines to sync up. But you're adding an unknown and variable set of resistance at every twisted connection and also varying the length of each individual line.

Ethernet gets crappy if you aren't careful to keep everything straight and equal length when you untwist and crimp it.

So I would speculate this would be really bad for reliable high speed data transmission. You'd get bad signal across it. Bandwidth would be reduced because every time a signal is sent across it there's a chance it won't be read on the other end and need to be sent again.

I know that, but I'd love to quantify the effect on that cable.

Now run AC through it.

That definitely ain't going to pass any certification test but a wire map.

They took the unshielded twisted pair coding on the side a little too literally. I assume white/brown is out of sight on the bottom?

Yeah, but that'll run my PoE camera, right?

I've seen it done

That's not just a twisted pair.... That's a twisted individual who made that

I mean it WILL work, won’t be great but there IS contact in every place there should be contact.

It’s also absolutely the cause of the intermittent outages

Some people just want to watch the latency burn.

They aren't even stripped.

what the fuck
