Optical Time-Domain Reflectometry

OTDR

(Optical Time Domain Reflectometer) A test instrument that analyzes the light loss in an optical fiber. Used to find faults, splices and bends in the line, it works by sending out a light pulse and measuring its reflection. Such devices can measure fiber lines that are longer than 150 miles.
