Twisted pair cables are network cables that are used in networks and consist of eight copper cables twisted in pairs. They are used for various applications such as cloud migration, DevOps and data security. They offer protection against electromagnetic interference fields and their shielding varies depending on the type.
There are different categories such as UTP (Unshielded Twisted Pair), STP (Shielded Twisted Pair), FTP (Folied Twisted Pair) with different applications and shielding. The cable structure includes wire pairs, core, cable sheath and optional shield. The choice of cable type (UTP, STP, FTP) depends on the respective requirements. Additional elements in twisted-pair cables can be two-core wires, filler cores, separating elements or plastic cores. These elements serve various functions such as grounding, filling cavities and separating wire pairs. Twisted pair cables are available in various categories (Cat 1 to Cat 8) with different transmission properties.
The advantages of twisting the cores in twisted pair cables are the reduction of interference from external fields, lower interference radiation and a reduction in crosstalk. This makes the cables easy and inexpensive to manufacture.
