What tool is used to attach connectors to the end of a cable?

The tool that is specifically designed to attach connectors to the ends of cables is the cable crimpers. Cable crimpers work by applying pressure to a connector, such as an RJ-45 for Ethernet cables, to secure the connector to the cable itself. This process ensures a stable and reliable connection that allows data to be transmitted effectively through the cable.

Cable testers are used to verify that cables are functioning properly and to check for any connectivity issues, but they do not attach connectors. A multi-tester, also known as a multimeter, is used for various electrical measurements, such as voltage, current, and resistance, but it does not have the capability to crimp connectors onto cables. Lastly, a cable certifier is a tool used to test the performance and quality of a cabling installation against specific standards, and while it verifies the integrity of the connection, it also does not attach connectors. Thus, cable crimpers are essential for the initial assembly of cables with connectors.
