CAT6 Cabling: What is the BIG DEAL about AWG (American Wire Gauge)?

CAT6 Cabling: What is the BIG DEAL about AWG (American Wire Gauge)?

By Steve Napoli | Senior Strategic Account Executive

Wire gauge is an index that indirectly (inversely and logarithmically) tells us the cross-sectional area of a round wire.

You may be asking, “Why does the gauge matter in my network’s racks? I mean, I use standard CAT6 cabling, and it works for me!”

If you’re cabling up 48 ports of CAT6 that doesn’t seem like a ‘big’ deal. However, consider this. 

Standard CAT6 cabling is typically 23AWG conductor.  That = .0226 inches in diameter per wire. So what? In terms of area, that = .2582 mm². Multiply that by your 48 cables. That adds up quickly to a robust bundle of goodness.

Where am I going with this?


So we know - the larger the gauge, the smaller the wire - but the relationship is logarithmic not linear. i.e., a 40 AWG solid wire has a circular mil area, as specified by the National

Bureau of Standards, of 9.61; a 30 AWG wire has a circular mil area of 100.5, a 20 AWG wire comes in at 1020, and a 10 AWG at 10380.

Back to the 23AWG typical CAT6 that occupies .2582 mm², and compare that to .0810mm². Sounds attractive when you have a bunch of those bundled together in your network rack, doesn’t it? 

I don’t know about you, but if I could reduce my waistline by a much smaller percentage, I would be ecstatic!

So, how do you get your hands on that thinner, sleeker, more attractive CAT6 cable? Contact CABLExpress today! And remember, it is the size of the WIRE, not the size of the wire with its insulation, that is measured in AWG.
