Cable Type	Shielding	Description	Use Case
UTP	None	Twisted wires to reduce EMI and crosstalk	Most common and basic type of cable
STP	Foil wrapping or copper braid jacket	Twisted wires wrapped with shielding material	Reduces EMI and crosstalk more than UTP
FTP	Foil wrapping around each twisted pair	Each pair of wires wrapped in foil for added protection	Provides better shielding than UTP
S/FTP	Combines FTP and STP shielding	Twisted wires wrapped in foil, then wrapped in a shielding material	Provides highest level of protection against EMI and crosstalk
