The measurement process of sending electrical pulses into a conductor and observing the returned signals to characterize the transmission line. It relies on the principle that any change in impedance causes a reflection. Technicians use this method to verify cable integrity, measure cable length, and pinpoint splices, crimps, or damage along copper networks.
Heard on the job
We used time-domain reflectometry to prove the fault was 400 feet out, right where the backhoe was digging.
