STP cables enhance the twisted pair design by adding an internal foil or braided shielding layer. This shield acts as a Faraday cage, protecting the internal signals from external electrical noise and preventing the cable's own signals from leaking out. It consists of color-coded copper wires twisted into pairs to cancel out electromagnetic interference (EMI) from adjacent pairs—a phenomenon known as crosstalk. The fundamental design of STP cables involves pairs of. That's the UTP vs.
