Abstract

This application relates to a fibre optic cable which is adapted for use in a distributed fibre optic sensor such as a distributed acoustic sensor. The cable (201) comprises at least one optical fibre (208) and a shear thickening non-Newtonian fluid (202) disposed within the cable. The presence of a shear thickening fluid in the cable means that in response to a mechanical vibration or strain such as due to an incident acoustic wave the apparent viscosity of the non-Newtonian fluid will increase. In effect the cable will stiffen which will increase the strain on the optical fibre used for sensing, and thus increase the sensitivity of the cable to incident signals. The non-Newtonian fluid may be a dilatant material and/or a rheopectic material and may comprise comprises a plurality of particles disposed within a liquid.
