What might be indicated if a cable passes a continuity test but fails an attenuation test?

When a cable passes a continuity test but fails an attenuation test, it suggests that while the cable is able to conduct signals across its length (as established by the successful continuity test), it is exhibiting excessive signal loss, which is identified through the attenuation test.

Continuity tests check for a complete path for electrical signals by verifying that the electrical circuit is unbroken. A passed continuity test indicates that the conductor paths within the cable are intact and properly connected. However, attenuation tests measure how much signal diminishes as it travels through the cable. If the cable fails this test, it means that there may be issues such as poor quality materials, improper installation, or damage to the cable that results in significant signal loss.

Therefore, excessive signal loss being indicated by the failure of the attenuation test is crucial for diagnosing potential issues that could affect performance in a data transmission context. This underlines the importance of both types of tests in assessing cable quality and functionality.
