OTDR meters
Optical Time Domain Reflectometers (OTDR's) OTDR devices for fiber optic lines, construction and maintenance of fiber optic communication systems Optical Time Domain Reflectometers (OTDR's) are used in the installation and maintenance of fiber optic cables, helping to identify cable problems such as breaks, bends or other types of physical damage. They are used to measure cable attenuation (signal loss) and dispersion (signal spread), which can affect the quality of data transmitted over the cable.
