<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 and "y" for the shield of the individual wire pairs.<br />U/UTP:<br />unshielded twisted pair; no overall shielding, no pair shielding, as a completely unshielded cable. <p><img src="/default-wAssets/img/glossary/copper-technology/UUTP.jpg" class="picture" alt="UUTP" /><br /></p> <p><br />F/UTP:<br />foil screened unshielded<br />twisted pair; overall shield made of<br />metallized<br />foil, no pair shield; also referred to in<br />practice as FTP cable</p> <p><img src="/default-wAssets/img/glossary/copper-technology/FUTP.jpg" alt="FUTP" /><br /></p> <p><br />U/FTP:<br />no overall shielding, wire pairs with<br />foil shielding</p> <p><img src="/default-wAssets/img/glossary/copper-technology/UFTP.jpg" alt="UFTP" /><br /></p> <p><br />SF/UTP:<br />braid and foil screened<br />unshielded twisted pair; Overall shielding<br />made of metallized foil and<br />braiding, no pair shielding</p> <p><img src="/default-wAssets/img/glossary/copper-technology/SFUTP.jpg" alt="SFUTP" /><br /></p> <p><br />S/FTP:<br />braid screened shielded<br />twisted pair; overall shield made of<br />braid, wire pairs individually<br />shielded with foil.

<p>Cable sharing involves dividing a single line between multiple connections. Cable sharing was popular with 10 and 100 Mbit/s Ethernet because a connection only required two wire pairs and a four-pair cable could therefore supply a double socket. Since Gigabit and 10 Gigabit Ethernet require all four pairs for a connection, cable sharing has become rare for reasons of future-proofing.&#160;</p>

Individual components are divided into categories according to their performance, and installed cabling according to classes. Currently, there are categories 5 (100 MHz / 1 Gbit/s) to 7A (1000 MHz / 10 Gbit/s).

Component categories for frequencies up to 100 MHz and data rates up to 1 Gbit/s. The values for Category 5 (Cat.5) are defined in the internationally valid ISO/IEC 11801 standard and in Europe in the EN 50173 series of standards. ANSI/TIA-568-D defines values for Category 5e ("enhanced Category 5"), 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 distance/transmission distance are defined as classes according to ISO/IEC and EN standards; the designations according to TIA differ from these. <br />Individual components:<br />EN: Category 5<br />ISO/IEC: Category 5<br />TIA: Category 5e<br />Cabling distance (from patch panel to connection box):<br />EN: Cabling distance Class D (permanent link)<br />ISO/IEC: Class D permanent link<br />TIA: Category 5e permanent link<br />Transmission distance<br />(complete connection including patch cable):<br />EN: Transmission distance Class D (Class D<br />channel)<br />ISO/IEC: Class D channel<br />TIA: Category 5e channel&#160;<br /></p> <p></p>

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. The values for the cabling path / transmission path 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 6A<br />ISO/IEC: Category 6A<br />TIA: Category 6A<br />Cabling link (from patch panel to junction box):<br />EN: Class EA cabling link<br />(Class EA permanent link) Class EA permanent link)<br />ISO/IEC: Class EA permanent link<br />TIA: Category 6A permanent link<br />Transmission link<br />(complete connection including patch cable):<br />EN: Transmission link Class EA (engl.
