What is STP (Shielded Twisted Pair) Cable?
- STP - Shielded Twisted Pair Cable is a type of copper telephone wiring in which each of the two copper wires that are twisted together are coated with an insulating coating that functions as a ground for the wires.
- The extra covering in shielded twisted pair wiring protects the transmission line from electromagnetic interference leaking into or out of the cable. STP cabling often is used in Ethernet networks, especially fast data rate Ethernets.
- STP is used in various kinds of networks to prevent crosstalk and electromagnetic interference. STP cable can also help to provide grounding.
- RJ-45 connectors are added at the both ends of the STP and UTP cable.
- STP is similar to UTP but with each pair covered by an additional copper braid jacket or foil wrapping. This shielding helps protect the signals on the cables from external interference.
- STP is more expensive than UTP but has the benefit of being able to support higher transmission rates over longer distances.
