What is the twisted-pair cable for Gigabit Ethernet?
Ethernet, Fast Ethernet and Gigabit Ethernet use the following types of cabling: 10Mbps: 10BASE-T: Category 3, 4 or 5 UTP/STP 100Mbps: 100BASE-TX: Category 5 UTP/STP 1000Mbps: 1000BASE-T: Category 5 UTP/STP Category 5 cable is preferred to be using with twisted-pair Ethernet in structured wiring environments. This will ensure correct operation of all ports at 10Mbps, 100Mbps or 1000Mbps. Note that for Gigabit Ethernet, all 4 pairs of the twisted-pair cable are used for transmission and receiving signals.
