Abstract:In an integrated sensing and communication optical network, the optical cable serves as the core transmission medium.It must be sensitive to minor vibrations yet robust enough to withstand strong impacts.However, it is difficult to reconcile these two contradictory properties in traditional materials, which restricts the performance improvement of the integrated sensing and communication optical network.This paper proposed a method of enhancing the coating with shear thickening material, whereby shear thickening fluid (STF) and shear stiffening gel (SSG) were alternately applied to the surface of the optical fibre to enhance both sensitivity and protection simultaneously.In the experiment, STF and SSG were coated alternately six times, increasing the diameter of the optical fibre from 240.599 μm to 279.032 μm.The average measured sensitivity of the fibre increases by 75.1% and its impact resistance improves by 40.6% after enhancement coating.These results demonstrate that the shear thickening material enhancement coating method can effectively overcome the contradiction between optical fibre measurement sensitivity and impact resistance, promoting the development of integrated sensing and communication optical networks.
