Time domain reflectometers are used to detect cable faults. It can test cables and detect faults up to a distance of 10000 feet. A TDR detects cable problems by sending a pulse and measuring the time of the pulse echo. Cable problems like poor splicing, discontinuity and poor joints can change the impedance of the cable which causes the pulse to be reflected back.
