Optical time-domain reflectometer

OverviewReliability and quality of OTDR equipmentTypes of OTDR-like test equipmentOTDR data formatAn optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or reflected ba
