Abstract: In a system and method of Optical Time-Domain Reflectometry a laser source outputs a laser pulse to an optical fiber. A processor samples a backscatter signal generated by the optical fiber in response to the laser pulse. Upon determining from the samples that the backscatter signal has an amplitude whereupon an element of a receiver is in a saturated operating state, the processor decreases the amplitude of subsequent samples of the backscatter signal output by the receiver to within an unsaturated operating state of the element of the receiver. Thereafter, upon determining from subsequent samples of the backscatter signal that the backscatter signal does not have (or no longer has) an amplitude whereupon the element of the receiver would be in the saturated state, the processor increases the amplitude of the samples of the backscatter signal output by the receiver for sampling by the processor.
