    An optical time- domain reflectometer ( OTDR) is an

    optoelectronic instrument used to characterize an optical

    fiber.

    An OTDR is the optical equivalent of an electronic time

    domain reflectometer.

    It injects a series of optical pulses

    into the fiber under test.

    It also extracts, from the same end

    of the fiber, light that is scattered ( Rayleigh backscatter)

    or reflected back from points along the fiber.

    ( This is

    equivalent to the way that an electronic time- domain

    reflectometer measures reflections caused by changes in the

    impedance of the cable under test.

    ) The strength of the return

    pulses is measured and integrated as a function of time, and

    plotted as a function of fiber length.
