  • Controlling a dynamic signal range in an optical time domain reflectometry
    Patent number: 7586617
    Abstract: A technique includes providing an optical source signal to an optical fiber to produce a backscatter signal. A receiver is provided to detect the backscatter signal. During an acquisition period in which the backscatter signal is present, a sensitivity of the receiver is varied with respect to time to regulate an input signal range of an amplifier of the receiver.
