OTDR
Short for Optical Time Domain Reflectometer, an instrument that analyzes the light loss in an optical fiber in optical network trouble shooting. An OTDR injects a short, intense laser pulse into the optical fiber and measures the backscatter and reflection of light as a function of time. The reflected light characteristics are analyzed to determine the location of any fiber optic breaks or splice losses.
