How to repair cut Ethernet cables?

To repair a cut Ethernet cable, first, strip the outer insulation of both ends to expose the inner wires, ensuring you have enough length for re-termination. Untwist the wire pairs and align them according to the T568A or T568B wiring standard, depending on your existing setup. Trim the wires to equal lengths, insert them into a new RJ45 connector, and use a crimping tool to secure the connector. Finally, test the cable with a network cable tester to ensure proper connectivity.
