Cat 6 must meet more stringent specifications for crosstalk and system noise than Cat 5 and Cat 5e. The design of Cat 6 required more stringent precision in manufacturing, which enabled reduced noise and crosstalk, thereby improving performance.
Cat 6 cable can be identified by the printing on the side of the cable sheath. Cat 6 patch cables are normally terminated in 8P8C modular connectors, using either TA or TB pin assignments; performance is comparable provided both ends of a cable are terminated identically.
If Cat 6-rated patch cables, jacks and connectors are not used with Cat 6 wiring, overall performance is degraded and may not meet Cat 6 performance specifications. The Cat 6 specification requires conductors to be pure copper. The industry has seen a rise in non-compliant or counterfeit cables, especially of the copper-clad aluminium wire CCA variety.
It was defined in Cat 6A also has an improved alien crosstalk specification as compared to Cat 6, which picks up high levels of alien noise at high frequencies. In general, the ISO standard for Cat 6A is the most stringent, followed nätverksanslutning cat6 kabel the European standard, and the American one 1 on 1 matching capability.
After the ratification of Cat 6, manufacturers began offering cables labeled as Category 6e. The intent was to purportedly market Cat 6e as an official upgrade to the Category 6 standard, with the name resembling the name of the Category 5e standard.
Officially, Cat 6e is not a recognized ISO standard. Category 8 is the next network cabling offering to be backward compatible. This consists of 90 meters ft of solid horizontal cabling between the patch panel and the wall jack, plus 5 meters 16 ft of stranded patch cable between each jack and the attached device.
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 larger than four times the outer diameter of the cable. Cable shielding may be required in order to avoid data corruption in high electromagnetic interference EMI environments.
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 of creating a ground loop. This undesirable situation may compel currents to flow in the network cable shield and these currents may in turn induce detrimental noise in the signal being carried by the cable.
