Abstract
Computer-implemented methods for performing enhanced resolution time-domain reflectometry are provided. Aspects include obtaining a plurality of waveforms by transmitting a first pulse on a transmission line, transmitting a second pulse on the transmission line, where the second pulse is transmitted after the first pulse by a delay, and capturing and measuring reflections of the transmitted pulses, wherein the delay corresponding to each of the plurality of waveforms is different. Aspects also include identifying a discontinuity of the transmission line based at least in part on the plurality of waveforms. Based on a determination that the transmission line includes the discontinuity, aspects include calculating third derivative curves for each of the plurality of waveforms and calculating a length of the discontinuity of the transmission line based on the third derivative curves. Aspects also include creating a notification indicating a location and the length of the discontinuity of the transmission line.
