Shielded Twisted Pair (STP) is a type of electrical cable used for data transmission. It consists of pairs of wires twisted together, which helps reduce electromagnetic interference. The wires are also encased in a protective shield, typically made of foil or braided copper, to further minimize external noise and crosstalk from nearby cables. STP is commonly used in networking applications, such as Ethernet connections, where reliable data transfer is essential. Its shielding makes it suitable for environments with high interference, like industrial settings. Overall, STP provides better performance compared to unshielded twisted pair (UTP) cables in challenging conditions.
