10 Gigabit Ethernet standards are meant to transmit Ethernet signals at 10 Gbps (10,000,000,000 bits per second) speed. Originally 10 Gigabit Ethernet was designed for fibre optic backbone systems. But later, 10GBase-T became the Ethernet Media Standard for running 10 Gigabit Ethernet over copper twisted pair cables.
10GBase-T networking components (jacks, ports and cables) looks same as the previous wired Ethernet standard’s components. 10GBase-T uses copper twisted pair cables.
10GBase-T running on Cat 6 twisted pair cables has a maximum possible cable length of only 55 meters. Cable types Cat 6a and above can carry data up to 100 meters similar to previous copper twisted pair wired Ethernet standards.
