Abstract:
1. A method of determining locations of acoustic disturbances of an optical fiber, the method comprising: injecting, at a remote sensing unit of a monitoring system, optical energy having a first wavelength into a first optical fiber deployed in a multi-dimensional layout, the multi-dimensional layout comprising a plurality of optical fibers, wherein the plurality of optical fibers has an overlapping point; receiving, at the remote sensing unit via the first optical fiber, an optical return signal; generating, by the remote sensing unit, a representative signal that is representative of the optical return signal and comprising a plurality of features of the optical return signal, the plurality of features associated with the acoustic disturbances impinging on the first optical fiber; transmitting, by the remote sensing unit, to an analysis engine of the monitoring system the representative signal as an encoded signal; and determining, by the analysis engine, locations of the acoustic disturbances based on an analysis of the representative signal.
