STP cables are widely used in computer and telephone networking, including wiring Ethernet connections for computer networks, as well as commercial and residential telephone connections. This provides the highest level of protection against EMI and crosstalk. The wires inside the cable are twisted and then shielded with 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 (SFTP) - A cable that is classified as shielded foil twisted pair (S/FTP) is a combination of both FTP and STP shielding. According to different shieldings, STP cables can be divided into several types:įoil Twisted Pair (FTP) - 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 work by attracting interference to the shield, then running it off into a grounded cable. Similar to UTP cable, STP cable contains an extra foil wrapping or copper braid jacket to help shield the cable signals from interference, thereby transporting data faster. It is smaller in size hence installation is easier as it does not fill up wiring ducts. It is the most compatible cabling and can be used with most other major networking systems and does not require grounding. It is less expensive and less costly compare to other networking media types. And as UTP cable bandwidth has improved to match the baseband of television signals, UTP is now used in some video applications as well, primarily in security cameras. UTP is also the most common cable used in computer networking. Thinner UTP cables are easy for routing through the tightest spaces and cable management panels, which further helps improve the air-flow and reduce the risk of network down-time.Įxcept for its use in many Ethernet networks and telephone systems. FS offers even thinner cables - Cat6 28AWG slim cables, which support 250MHz bandwidth and 1000-T Ethernet, allowing for more reliable data transmission. 24 AWG (short for American Wire Gauge) is the most commonly seen size of UTP cables. It has no foil wrap shielding or braided shielding screen, which makes the cable smaller in diameter. UTP cable is low-cost network cable built with a pair of insulated conductors twisted together and covered with a plastic jacket for protection. Below content explains their differences in detail. Cable with shielding is known as shielded twisted pair (or STP cable) and without as unshielded twisted pair (or UTP cable). For additional noise immunity, twisted pair cabling may be shielded.
