OTDR (Optical Time Domain Reflectometer)

An Optical Time Domain Reflectometer (OTDR) is a testing device used to analyze fiber optic cables. It sends pulses of light into the fiber and measures the reflections that come back, caused by faults, connectors, or bends. By timing these reflections, the OTDR creates a detailed map of the cable’s condition, helping technicians identify issues like breaks, damage, or loss points. It’s a crucial tool for maintaining reliable fiber optic networks, ensuring signals travel efficiently over long distances without interruption.
