TDR (Time Domain Reflectometry)

Time Domain Reflectometry (TDR) is a technique used to detect faults and measure the condition of cables by sending a short electrical pulse along the wire. When the pulse encounters an impedance change—such as a break, corrosion, or a connection issue, it reflects back toward the source. By analyzing the time it takes for the reflection to return and its characteristics, technicians can pinpoint the location and nature of problems within the cable. TDR is widely used in industries like telecommunications, electrical maintenance, and infrastructure management to ensure cable integrity and diagnose issues efficiently.
