TP – Twisted Pair A TP cable (TP) is a symmetrical copper cable used for data transfer, which consists of two cores (1 core pair) which are twisted around one another. In IP-based networks, cables with four core pairs are normally used. The data transfer takes place in a single direction per core pair. For a data connection 2 core pairs are required (sending and receiving). In the case of higher data transfer standards (e.g. 1000 BASE-T Ethernet) all 4 core pairs are used (2x sending and 2x receiving). TP cables come in various unshielded and shielded designs, each with different core diameters. The performance capability of a TP cable is specified by its category (e.g. Cat 5). -> Cat. 5
