COMPARE CABLE SHIELD TYPES

Comparison of some old and new abbreviations, according to ISO/IEC 11801

UTP U/UTP none none
STP U/FTP none foil
FTP F/UTP foil none
S-STP S/FTP braiding foil
S-FTP SF/UTP foil, braiding none
SFTP foil Shield

The code before the slash designates the shielding for the cable itself, while the code after the slash determines the shielding for the individual pairs:


TP = Twister Pair

U = Unshielded

F = Foil Shielding

S = Braided Shielding


Note that different vendors and authors use different terminology (i.e. STP has been used to denote both STP-A,S/STP, and S.UTP).
