Category 5e – Structured Data Cabling

Cat 5e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. It was formally defined in 2001 as the TIA/EIA-568-B standard, which no longer recognizes the original Cat 5 specification. Although 1000BASE-T was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BASE-T. Despite the stricter performance specifications, Cat 5e cable does not enable longer cable distances for Ethernet networks: cables are still limited to a maximum of 100 m (328 ft) in length (normal practice is to limit fixed (“horizontal”) cables to 90 m to allow for up to 5 m of patch cable at each end, this comes to a total of the previous mentioned 100m maximum..

Category 6 – Structured Data Cabling

Commonly referred to as Cat 6, it is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat 6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T / 1000BASE-TX (Gigabit Ethernet). It is expected to suit the 10GBASE-T (10Gigabit Ethernet) standard, although with limitations on length if unshielded Cat 6 cable is used. Category 6 cables can be identified by the printing on the side of the cable sheath.

Cat 6a – Structured Data Cabling

The latest standard from the TIA for enhanced performance standards for twisted pair cable systems was defined in February 2008 in ANSI/TIA/EIA-568-B.2-10. The global cabling standard ISO/IEC 11801 has been extended by the addition of amendment 2
Category 6a (or Augmented Category 6) operates at frequencies up to 500 MHz—twice that of Cat 6.
Cat6a can support 10 Gbit/s applications (especially 10GBaseT) up to a maximum distance of 100 meters (330 ft) with improved specifications, particularly in the area of Alien Cross-talk (AXT).

Category 7 – Structured Data Cabling

(Cat 7), (ISO/IEC 11801:2002 category 7/class F), is a cable standard for Ethernet and other interconnect technologies that can be made to be backwards compatible with traditional Cat 5 and Cat 6 Ethernet cable. Cat 7 features even more strict specifications for crosstalk and system noise than Cat 6. To achieve this, shielding has been added for individual wire pairs and the cable as a whole. The Cat 7 cable standard has been created to allow 10 Gigabit Ethernet over 100 m of copper cabling (also, 10-Gbit/s Ethernet now is typically run on Cat 6a). The cable contains four twisted copper wire pairs, just like the earlier standards connectors. Category 7 cable is rated for transmission frequencies of up to 600 MHz.
