Understanding the Shield Type Codes
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 = Twisted Pair
- U = Unshielded
- F = Foil Shielding
- S = Braided Shielding
Note that different vendors and authors use different terminology. For example, STP has been used to denote STP-A, S/STP, and S/UTP.
