An 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
The optical time domain reflectometer (OTDR) performs similar tests on optical fiber, particularly single mode, often installed as long underground or aerial lines. If a transmission line is
