What does TDR stand for in cable testing?

TDR stands for Time Domain Reflectometer, which is a specialized instrument used in cable testing. It works by sending a pulse of energy down the cable and measuring the time it takes for any reflections to return. This reflection occurs when there is a change in impedance due to faults, splices, or connectors within the cable. By analyzing these reflections, technicians can locate issues such as breaks, short circuits, or other irregularities in the cable's integrity.

This method is particularly valuable for troubleshooting and maintaining cable systems, helping field technicians assess the quality and performance of the cabling infrastructure. The precision of TDR readings allows for effective diagnostics, helping to ensure that any faults can be quickly identified and addressed, ultimately improving the overall reliability of the network.
