To embellish the below some, the twisted pairs in a CAT5 cable have different
twists, e.g.,
Pair color[cm] per turnTurns per
[m]Green1.5365.2Blue1.5464.8Orange1.7856.2Brown1.9451.7
So, one would assume the Zo for each pair is different....I suspect the
difference isn't that much but....thought I'd "axe around"
