Unshielded but not so twisted wire pairs in this Ethernet cable

It is essentially multiple twin lead transmission lines, but yeah, lacking the benefits of twisting.

And there is that one “split pair” that goes to pins 3 and 6. If other pairs are close what they should, this definitely has wrong impedance and more noise pick up.

Yeah this cable probably performs like crap.
