This tutorial helps your understand how to wire a 10BaseT, 100BaseT or 1000BaseT connector with Category 5, 5e, 6, 6e cable and RJ45 connectors using USOC 568B wiring standards.

RJ45 is a standard type of connector for network cables. RJ45 connectors are most commonly seen with Ethernet cables and networks.

RJ45 connectors feature eight pins to which the wire strands of a cable interface electrically. Standard RJ45 pintouts define the arrangement of the individual wires needed when attaching connectors to a cable.
