Pinout of Ethernet 10/100Base-T ( RJ-45) connector and layout of 8 pin RJ45 (8P8C) female connector and 8 pin RJ45 (8P8C) male connectorEthernet 10base-T / 100base-TX pinout. Widely used in ethernet network devices. The connector of 10Base-T, 100Base-TX and 1000base-T.. The TIA/EIA-568-A standard (IEEE 802.3) specifies two wiring schemes to be employed in Category 5 UTP/STP installations. The difference between the T568A and T568B schemes is that pairs 2 and 3 are reversed. Although 10Base-T only needs two pair, all four pairs must be terminated in either the T568A or T568B scheme.

T568 WIRING DIAGRAM FOR 10BASE-T AND 100BASE-T NETWORKS (IEEE 802.3) Most new Local Area Network (LAN) installations use either UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) Category 5 (CAT5) cable to wire either a 10Base-T or 100Base-T network topography. The following chart details the T568 standards for these networks.
