Abstract
An optical fiber having at least one fiduciary mark is provided. The at least one fiduciary mark is located at one or more axial positions along the optical fiber. The at least one fiduciary mark is configured to produce at least one change in a backscattering signal in the optical fiber. The at least one change in a backscattering signal may be an abrupt change in the backscattering signal. The abrupt change in the backscattering signal occurs over a length of the optical fiber that is of the order of or less than a spatial resolution of an interrogation system employed to detect the backscattering signal.
