Which cabling term best describes a cable that has no shielding around the twisted pairs?

• A. Shielded Twisted Pair
• B. Unshielded Twisted Pair
• C. Coaxial Cable
• D. Fiber Optic Cable

Answer: (B)

The key idea is whether the twisted-pair cable has shielding. A cable described as having no shielding around the twisted pairs is called Unshielded Twisted Pair. This type is simple, flexible, and cost-effective, but it is more susceptible to electromagnetic interference, which is why shared office ethernet runs often use it. Shielded Twisted Pair includes a foil or braided shield to reduce EMI, so it wouldn’t fit the description. Coaxial cable isn’t a twisted-pair arrangement at all—it uses a single conductor with its own shield. Fiber optic cable carries light through glass and has no metallic shielding or twisted pairs. So the term that best matches “no shielding around the twisted pairs” is Unshielded Twisted Pair.
