WebSep 22, 2024 · Shielded twisted pair (STP) cabling consists of wire pairs twisted around each other to reduce crosstalk. The wires in the pairs are insulated with color-coded plastic, and the pairs collectively are wrapped in foil to reduce EMI. Similar to Coax, around the foil-covered wire pairs is a braided copper mesh to reduce EMI, which is surrounded by ... WebElectronic symbol for a shielded wire. A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. [1] This shield is usually covered by an outermost layer of the cable. Common types of cable shielding can most broadly be categorized as foil type (hereunder ...

WebThe STP cable shown uses four pairs of wires, each wrapped in a foil shield, which are then wrapped in an overall metallic braid or foil. For many years, STP was the cabling structure specified for use in Token Ring network installations. With the decline of Token Ring the demand for shielded twisted-pair cabling also waned. WebEach pair of wires is wrapped in a metallic foil (see Figure 8-3). The four pairs of wires then are wrapped in an overall metallic braid or foil, usually 150-ohm cable.
