What is reflection in an optical time domain reflectometer
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 back from points along the fiber. An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. OTDR testing analyzes fiber optic cable performance from end to end by testing components along the cable, including connection points, bends, and splices. They are mostly used in the technology of optical fiber communications for testing fiber-optic links (e.
