What Is Time-Domain Reflectometry?_
The method determines the distance to a fault or anomaly by dividing the round-trip propagation time by the known velocity of propagation in the medium. It applies to both copper twisted-pair and coaxial assemblies used for control, power, or low-speed signaling links. Results appear as a trace that shows the location and nature of opens, shorts, or impedance mismatches along the run.
Technical Details
A step or impulse source launches the test signal while a sampling receiver captures returning energy at successive time intervals. The instrument converts elapsed time to distance once the propagation velocity factor of the cable type is entered. Trace features such as rising edges, dips, or ringing indicate connector transitions, kinks, or damaged sections without requiring physical access to the entire path.
How Leviathan Systems Works with Time-Domain Reflectometry
Field crews apply TDR during commissioning of copper-based management and telemetry cabling inside racks that house GPU assemblies and their associated networking hardware.
