The optical distance along a buried optical fiber (12) from a particular location (13) therealong to a central facility (10) is measured by first applying an intentional stress to the fiber in the form of a vibration signal (35) transmitted into the ground. A timing signal (36) is transmitted to the central facility (10) in synchronism with the application of the stress. Using the timing signal as a reference, the central facility can determine the time difference between when the stress was applied, and when the central facility detected the stress. From the time difference, and a knowledge of the propagation rate of the timing signal, the central facility can establish the optical distance to the particular location at which the stress was applied.
