How do you terminate RJ 45?

To terminate an RJ45 connector, first, strip about 1 inch of the outer insulation from the end of the Ethernet cable using a wire stripper. Untwist the pairs of wires and arrange them according to the T568A or T568B wiring standard, ensuring correct color order. Trim the wires to about half an inch, insert them into the RJ45 connector, and use a crimping tool to secure the connector onto the cable, ensuring each wire makes contact with the metal pins. Finally, test the connection with a cable tester to ensure proper termination.
