Belonging to the sixth generation of twisted pair Ethernet cabling and also called Category6 cable, Cat6 means a cable standard for Gigabit Ethernet and other network protocols, defined by the Electronic Industries Association and Telecommunications Industry Association (usually referred to as EIA/TIA).
Like the previous generation Cat5, Cat6 cable also contains four pairs of copper wire. However, the difference between the two is that unlike Cat5, Cat6 can fully utilize all four pairs. It can support Gigabit Ethernet speeds up to 1 gigabit per second (GBPS). Cat6 cable can also support communications at a much faster rate, more than double the speed of Cat5e, which is the other familiar standard for Gigabit Ethernet cabling. An enhanced version of Cat6 is known as Cat6a that can support up to 10 GBPS speeds. Like most other types of twisted pair EIA/TIA cabling, individual Cat6 cable runs are also usually restricted to a maximum length of 100m. Cat6 cable can be identified by the printing on the side of the cable sheath.
When used as a patch cable, Cat6 cable is more often than not terminated in 8P8C modular connectors. Cat6 connectors are made to higher standards for cutting down on noise generated by crosstalk and system interference. In comparison with Cat5 or Cat5e, its attenuation, NEXT (Near End Crosstalk), and PSNEXT (Power Sum NEXT) are all lower by a considerable degree. You may need the help of a special modular piece for attaching a Cat6 cable to 8P8C connector if the cable is considerably large.
