Low-Voltage Cabling Practice Test

What are the two conductors in a UTP pair called?

Tip and Ring Positive and Negative Sleeve and Plug Green and Red

Correct Answer:

Tip and Ring

Explanation:

The two conductors in a UTP pair are called tip and ring. This naming comes from old telephone wiring, where the two wires in a single pair were designated as the tip wire and the ring wire. The signal is carried as the voltage difference between tip and ring, so naming the pair by these two conductors makes sense historically and is still used in cabling discussions. In modern Ethernet, we usually refer to pairs by color and pinout, but tip and ring remains the standard term for the two wires that form a single pair. The other phrases don’t fit because they describe polarity in DC systems, connector parts, or arbitrary color labels rather than the established two-wire pair terminology.
