What is the typical conductor size range for UTP cables?

• A. 20-18 AWG
• B. 24-22 AWG
• C. 28-26 AWG
• D. 26-24 AWG

Answer: (B)

UTP cables in Ethernet systems use relatively small copper conductors to balance signal quality with flexibility. The standard conductor size is centered on 24 AWG, which provides the right mix of low resistance and manageable stiffness for in-wall and patch-ccord use. Many UTP cables also come in thicker 22 AWG, which lowers resistance slightly and can improve attenuation over distance, though it makes the cable a bit stiffer. So the typical range you’ll see is about 24 to 22 AWG. Other ranges don’t fit the common practice: 20–18 AWG would be much thicker, making cables stiffer and altering impedance; 28–26 AWG is too thin, increasing resistance and signal loss; 26–24 AWG is plausible but doesn’t reflect the common presence of 22 AWG in some UTP cables.
