摘要
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.
