Which type of Twisted Pair Cable is characterized by the absence of any shielding?

Unshielded Twisted Pair (UTP) cable is distinguished by its lack of any shielding around the individual pairs of wires. This absence of shielding allows it to be more flexible and cost-effective for various networking applications, such as Ethernet connections in local area networks (LAN). UTP typically consists of pairs of wires twisted together to help reduce electromagnetic interference and crosstalk from adjacent pairs, which improves data transmission fidelity.

Shielded Twisted Pair (STP) cable, in contrast, incorporates shielding to minimize interference, making it suitable for environments with higher electromagnetic interference. Fiber Optic Cable transmits data as light through glass or plastic fibers and does not use twisted wire pairs, while Coaxial Cable consists of a single conductor surrounded by insulation and a shield, which also differentiates it from Twisted Pair designs. Thus, the correct identification of UTP as the type of cable without any shielding is essential for understanding its structure and application in networking.
