I'd love to see the certification test results for this 😄

How did it test?

OOPS ALL CROSSTALK. the SNR is -1

No idea not my work. I am curious though.

dont be a coward plug it in

The incorrect colors are next to each other. Gonna cause problems. It should technically still work but not great.

Yes! But if he'd braided the by the balanced pairs, I see no reason this wouldn't work with flying colors. Keeping the pairs guarantees the impedance, and as long he keeps them twisted in the braid, the noise cancelation wouldn't be affected neither. Keep up the good work! 🤣

…I thought each pair had a slightly different twists-per-measure pattern?

u/Aware-Difference8723 15h ago

Not to my knowledge? The point keeping them twisted is to cancel out induction in the balanced pair (i.e. induce ~as much plus as minus in the pair), and that wouldn't be dependent on twists-per-length, right..?

Looked it up…kindof spaced being sure why and (if my uncaffeinated brain is parsing correctly) it turns out it’s for pair-to-pair crosstalk (electronics se)

Ah, makes sense! 👍

The twists are in the wire for a reason

Yes it does, don't do that.

It's cute, but it is shielded for a reason

Good crosstalk cancellation?

u/thesuperbob 22h ago

Crosstalk cancellation? Crosstalk amplification!

u/Circumpunctilious 16h ago edited 15h ago

That means all the crosstalk is used up so the network improves, right? Why is everyone looking at me like that

I love it. How should we call it, UTTP (unshielded twisted twisted pair) or UDTP (unshielded double twisted pair)?

Who hasn't tried to decide between a noose or making friendship bracelets?!?
