<p>According to ISO/IEC 11801, cables and wires are classified according to their shielding. The designation scheme is "x/yTP", where "x" stands for the overall shield, "y" for the shield of the individual wire pairs.<br />U/UTP:<br />engl. unshielded twisted pair; no<br />overall shield, no pair shield, as<br />supplementary unshielded cable</p> <p><img src="/default-wAssets/img/glossar/kupfertechnik/UUTP.jpg" class="picture" alt="UUTP" /><br /></p> <p><br />F/UTP:<br />engl. foil screened unshielded<br />twisted pair; overall shield made of<br />metallized<br />foil, no pair shield; in<br />practice also referred to as FTP cable</p> <p><img src="/default-wAssets/img/glossar/kupfertechnik/FUTP.jpg" alt="FUTP" /><br /></p> <p><br />U/FTP:<br />no overall shield, wire pairs provided with<br />foil shield</p> <p><img src="/default-wAssets/img/glossar/kupfertechnik/UFTP.jpg" alt="UFTP" /><br /></p> <p><br />SF/UTP:<br />engl. braid and foil screened<br />unshielded twisted pair; overall shield<br />made of metallized foil and<br />braid, no pair shield</p> <p><img src="/default-wAssets/img/glossar/kupfertechnik/SFUTP.jpg" alt="SFUTP" /><br /></p> <p><br />S/FTP:<br />engl. braid screened shielded<br />twisted pair; overall shield made of<br />braid, wire pairs individually provided with<br />foil shield.

<p>With cable sharing (cable = cable/line, to share = divide), a line is divided into several connections. Cable sharing was popular for Ethernet with 10 and 100 Mbit/s because a connection only required two pairs of wires and a four-pair cable could therefore supply a double socket. Since Gigabit and 10 Gigabit Ethernet require all four pairs for one connection, cable sharing has become rare for reasons of future-proofing. </p>

<p>Individual components are divided into categories according to their performance, installed cabling according to class. There are currently categories 5 (100 MHz / 1 Gbit/s) to 7A(1000 MHz / 10 Gbit/s). </p>

<p>Component categories for frequencies up to 100 MHz and data rates up to 1 Gbit/s. The internationally valid ISO/IEC 11801 standard defines the values of Category 5 (Cat.5), in Europe in the EN 50173 series of standards. ANSI/TIA-568-D defines values for Category 5e ("enhanced Category 5", sometimes referred to as Category 5E in German), but these only apply in the USA and Canada; in addition, individual values differ from those in ISO/IEC 11801 and EN 50173. <br />The categories only apply to individual components. The values for the cabling link / transmission link are defined as classes according to ISO/IEC and EN standards, the designations according to TIA differ from this. <br />Individual components:<br />EN: Category 5<br />ISO/IEC: Category 5<br />TIA: Category 5e<br />Cabling route (from the patch panel to the junction box):<br />EN: Class D cabling route<br />Permanent cabling route: Class D Class D<br />permanent link)<br />ISO/IEC: Class D permanent link<br />TIA: Category 5e permanent link<br />Transmission link<br />(complete connection including patch cable):<br />EN: Class D<br />channel link<br />.

ANSI/TIA 568D also defines values for Category 6, but these only apply in the USA and Canada; in addition, individual values differ from those in ISO/IEC 11801 and EN 50173. <br />The categories only apply to individual components.

The values for Category 6A (Cat.6A) are defined in the internationally valid ISO/IEC 11801 standard, in Europe in future editions of the EN 50173 series of standards. ANSI/TIA-568-D also defines values for Category 6A, but these only apply in the USA and Canada; in addition, individual values differ from those in ISO/IEC 11801 and EN 50173. Another difference: The "A" is subscripted in the internationally valid ISO/IEC and the European EN, but not in the TIA. <br />The categories only apply to individual components.
