Using this CAT 5 Ethernet cable is super easy. Just plug one end into your device, like a computer or router, and the other end into the corresponding port of the other device. That's it, and you'll have a stable network connection. When using it, avoid bending the cable too sharply as it may damage the internal copper cores. For maintenance, keep it away from moisture and high - temperature areas. If it gets dirty, you can gently wipe it with a dry cloth. Also, don't pull the cable forcefully when unplugging it to prevent damage to the connector.
