Shielded Twisted-pair (STP)
Shielded Twisted-pair (STP) (30.3.4) Shielded twisted-pair (STP) provides better noise protection than UTP cabling. However, compared to UTP cable, STP cable is significantly more expensive and difficult to install. Like UTP cable, STP uses an RJ-45 connector. STP cables combine the techniques of shielding to counter EMI and RFI, and wire twisting to counter crosstalk….
