Category 6 cable, commonly referred to as Cat 6 (Cat6), is a standardized cable for Gigabit Ethernet and other network physical layers. It is backward compatible with the Category 5/5e cable standards.
Compared with Cat 5 and Cat 5e, Cat 6 features more protection for crosstalk and system noise. The Cat 6 cable standard also provides performance of up to 250 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet), and 10GBASE-T (10-Gigabit Ethernet).
Category 6 cable can be identified by the printing on the side of the cable.
