COMPARE CABLE SHIELD TYPES
Comparison of some old and new abbreviations, according to ISO/IEC 11801.
| Old name | New name | Cable Screening | Pair Shielding |
|---|---|---|---|
| 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 = twisted 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).
NOTE Sometimes the letter P in the abbreviation is replaced by Q to characterise a quad construction.
