Abstract: A pressure sensing cable in one embodiment includes an optical fiber having a first core and a second core. The first core extends along a length of the cable, and is sized and configured to provide propagation of light along the first core along the length of the cable. The first core has a first mode index corresponding to the speed of light propagation along the first core. The second core extends along the length, is spaced a distance from the first core, and is sized and configured to provide propagation of light along the second core along the length of the cable. The second core has a second mode index corresponding to the speed of light propagation along the second core. The second mode index is different from the first mode index, wherein light propagates along the second core at a different speed than along the first core.
