10GBASE-T is an Ethernet physical-layer standard that carries 10 Gbps over copper unshielded twisted-pair (UTP) cable. It uses all four twisted pairs, totaling eight wires, through an 8P8C connector. section 3.3.2 section 3.5
Key points for cable selection:
- Unlike 10BASE-T and 100BASE-T, which use two wire pairs, 10GBASE-T uses all four pairs. section 3.3.2
- The maximum cable length is 100 meters for UTP Ethernet connection types. section 3.5
- Twisting reduces electromagnetic interference between wires in each pair. section 3.5
Figure 3.7 Pin and wire pairs used on 1000BASE-T and 10GBASE-T connections. All eight wires of the cable are used.
Use the pin-and-wire diagram to verify that 1000BASE-T and 10GBASE-T connections use all eight cable wires. section 3.3.2
