2.5GBASE-T and 5GBASE-T

IEEE 802.3bz, NBASE-T and MGBASE-T are standards for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s. These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds. The resulting standards are named 2.5GBASE-T and 5GBASE-T.[1][2][3]

NBASE-T refers to Ethernet equipment that can automatically use training to operate at speeds of 2.5, 5, or 10 Gbit/s, depending on the quality of the cable, in connection with autonegotiation to support additional link speeds (10, 100 or 1000 Mbit/s), depending on the capabilities of the equipment at the other end of the cable.^{[citation needed]}
