Why is a cable tester used in telecommunications installation?

A cable tester plays a crucial role in telecommunications installation by checking for connectivity and integrity of the cables. This device assesses whether the cables are correctly wired and if they can transmit signals without interference or loss. Connectivity is fundamental to ensuring that data sent over the cables reaches its destination effectively, while integrity involves checking for any potential faults such as shorts, opens, or crossed wires.

In addition to ensuring the cables are operational, cable testers can provide insights into the quality of the installation by verifying that each connection is secure and that there are no anomalies that could affect performance. This functionality is essential during the installation process and also plays a critical role in ongoing maintenance, allowing technicians to swiftly diagnose any issues that may arise over time.
