A Time-Domain Reflectometer is a tool used to detect cable faults. This device operates by sending a brief signal pulse down the cable and looking for its reflection to bounce back. By analyzing the reflected pulse, it is possible to make judgments about the quality of the cable segment. More advanced units can not only detect and identify the nature of the problem, but give a reasonably accurate indication of the problem’s location (distance from the point of the test). There is also a device known as an OTDR, which is an Optical Time-Domain Reflectometer for fiber-optic cables.
