You have been asked to test and troubleshoot an installed base of cabling that is believed to be causing network problems. You are finding that there are high levels of return loss upon initial testing. What testing will best determine the reasons for these failures?

A time domain reflectometer (TDR) is the best choice in this situation. TDR can accurately locate and diagnose faults such as high levels of return loss by sending a signal down the cable and analyzing the reflections that come back. This allows the tester to pinpoint the exact location of the fault and determine the appropriate corrective action. Power meters and continuity testing are not designed to diagnose return loss, and Level II testing may not be necessary at this stage.
