You may be
confused with the Ethernet cables using individual foil-shielded pair and
overall shield constructions. Because there are some differences between standards
in North American and some other international organizations.
Some website
like the Siemon listed the naming rules of Ethernet cables. What are
they? Let’s take a look.
This cable terminology is outlined below and
is based upon the ISO/IEC 11801:2002 annex E standard systematic naming
convention shown in the following figure.
UTP
(Categories 3, 5e and 6)
UTP cable constructions feature unshielded
twisted-pairs enclosed within an overall thermoplastic jacket as shown in
figure 1. UTP cables are compatible with Siemon MAX®, CT®, SM®, HD®, S210®,
S110®, and S66™ product lines.
F/UTP
(Categories 5e and 6)
F/UTP cable constructions feature unshielded
twisted-pairs surrounded by an overall conductive mylar-backed aluminum foil
shield and enclosed within an overall thermoplastic jacket as shown in figure
2. F/UTP cables are compatible with Siemon screened MAX, screened HD5, screened
CT, and screened SM product lines. TIA and legacy Siemon materials referred to this
cable type as "ScTP", "screened" or "FTP".
S/FTP
(Category 7)
S/FTP cable constructions feature
individually foil-shielded twisted-pairs surrounded by an overall braid and
enclosed within an overall thermoplastic jacket as shown in figure 3. S/FTP
cables are compatible with Siemon TERA™ and screened MAX product lines. Legacy
Siemon materials referred to this cable type as "PiMF",
"STP", "SSTP" or "fully shielded".
