![]() ![]() This provides the highest level of protection against EMI and crosstalk. The wires inside the cable are twisted and then shielded with a foil wrapping, then the 4-pair grouping of foiled wires are shielded by a wrapping of either foil or a flexible braided screening. Shielded Foil Twisted Pair (S/FTP)Ī cable that is classified as S/FTP or Shielded Foil Twisted Pair is a combination of both FTP and STP shielding. With FTP cables, each twisted pair of cables is wrapped in a shielding of foil to protect the cable from EMI and crosstalk. STP cables are similar to UTP cables, where the wires are twisted together and then wrapped with a shielding or screening material which consits of foil wrapping or a copper braid jacket. The cable contains pairs of wires twisted together to help reduce and prevent electromagnetic interference. This is the most used and most basic type of cable. Unshielded Twisted Pair (UTP)Īs the title states, a UTP cable has no shielding. A twisted pair cable is cheap as compared to other transmission media. Below we breakdown the most widely used types of shielding available for Ethernet cables and what they mean. Twisted pair is a physical media made up of a pair of cables twisted with each other. The type of shielding a copper cables have can have a tremendous effect on the stability, performance, speed, and longevity of the cable and ultimately your network. What is the difference between UTP, STP, FTP, and S/FTP?
