What is the purpose of a cable tester?

The purpose of a cable tester is to verify the integrity and performance of network cables. This device is essential in ensuring that cables are functioning properly and can support the required data transmission speeds without errors. Cable testers check for various issues such as continuity, signal loss, and wiring faults, providing a clear indication of whether a network cable is suitable for use in a given environment. This functionality is critical for diagnosing problems in network setups, ensuring that all connections are robust and reliable before further configurations or uses are made.

Understanding the importance of a cable tester in network installations can help technicians maintain optimal network performance and reduce downtime caused by faulty connections.
