Shielded twisted pair STP cable was originally designed by IBM for token ring networks that include two individual wires covered with a foil shielding, which prevents electromagnetic interference, thereby transporting data faster.

STP is similar to unshielded twisted pair UTP ; however, it contains an extra foil wrapping or copper braid jacket to help shield the cable signals from interference. STP cables are costlier when compared to UTP, but has the advantage of being capable of supporting higher transmission rates across longer distances. The effectiveness of the additional covering varies according to the substance used for the shielding, such as: Frequency Thickness Type of electromagnetic noise field Distance from the shield to the noise source Shield discontinuity Grounding practices Some STP cablings make use of a thick copper braided shield which makes the cable thicker, heavier, and in turn much more difficult for installation as compared to the UTP cables.

At the same time, the foil shield around the wire pairs ensures good electrical insulation. When laying UTP cables, there is also the fact that the operator must generally maintain a large distance from supply cables here. With shielded cables, a separator plate is sufficient. It allows you to organize patch management in a clear and space-saving way. Find a local Trader.

Advantages of the UTP: It is a less costly and less expensive unshielded wire from another network medium.

Its size is small, and hence the installation of the UTP is easier. A shield is an electrically conductive material that is used to wrap a wire or cable. Two main types of shields used for cables are foil and braid. Foil shielding uses a thin foil of aluminum. Foils provides complete coverage for the cables. Since the foil is thin, grounding work is difficult.
