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, 1000BASE-T/1000BASE-TX and 10GBASE-T .Whereas Category 6 cable has a reduced maximum length when used for 10GBASE-T; Category 6a cable, is characterized to 500?MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same distance as previous protocols. The heavier wire in some Cat 6 cables makes them too thick to attach to standard 8P8C connectors without a special modular piece, resulting in a technically out-of-compliance assembly. Because the conductor sizes are generally the same, Cat 6 jacks may also be used with Cat 5e cable. Category 6 cables can be identified by the printing on the side of the cable sheath. Cat 6 patch cables are normally terminated in 8P8C modular connectors. If Cat 6 rated patch cables, jacks and connectors are not used with Cat 6 wiring; overall performance is degraded to that of the cable or connector. Connectors use either T568A or T568B pin assignments; although performance is comparable provided both ends of a cable are the same. Category 6 and 6a cable must be properly installed and terminated to meet specifications. The cable must not be kinked or bent too tightly (the bend radius should be at least four times the outer diameter of the cable. The wire pairs must not be untwisted and the outer jacket must not be stripped back more than .Cable shielding may be required in order to improve a Cat 6 cable's performance in high electromagnetic interference (EMI) environments. This shielding reduces the corrupting effect of EMI on the cable's data. Shielding is typically maintained from one cable end to the other using a drain wire that runs through the cable alongside the twisted pairs. The shield's electrical connection to the chassis on each end is made through the jacks. The requirement for ground connections at both cable ends creates the possibility that a ground loop may result if one of the networked chassis is at different instantaneous electrical potential with respect to its mate. This undesirable situation may compel currents to flow between chassis through the network cable shield, and these currents may in turn induce detrimental noise in the signal being carried by the cable.The latest standard from the for enhanced performance standards for twisted pair cable systems was defined in February 2009 in ANSI/TIA-568-C.1. Category 6a is defined at frequencies up to 500?MHz-twice that of Cat. 6. Category 6a performs at improved specifications, in particular in the area of alien crosstalk as compared to Cat 6 UTP, which exhibited high alien noise in high frequencies. The global cabling standard has been extended by the addition of amendment 2. This amendment defines new specifications for Cat. 6A components and Class EA permanent links. This new global cat. 6A/Class EA specifications require a new generation of connecting hardware offering far superior performance compared to the existing products that are based on the American TIA standard. Most important point is a performance difference between ISO/IEC and EIA/TIA component specifications for the NEXT transmission parameter. At a frequency of 500?MHz, an ISO/IEC Cat. 6A connector performs 3 dB better than a Cat. 6A connector that conforms to the EIA/TIA specification. 3?dB equals 50% reduction of near-end crosstalk noise signal power; see 3dB-point.
