Topband: Zo of an individual CAT5 twisted pair

[James Rodenkirch]

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"
