| 本文针对通感一体光网络中对光缆性能相互矛盾需求，提出了一种基于剪切增稠材料涂覆的创新解决方案。通感一体光网络要求光缆同时具备优异的抗冲击能力以确保通信稳定性，以及高灵敏度以实现微小动态应变的精确测量。为解决这一矛盾，本文采用在光纤表面交替涂覆剪切增稠液（STF）和剪切变硬胶（SSG）的方法，经过6次涂覆后，光纤直径从240.599μm增加至279.032μm。实验结果表明，涂覆剪切增稠材料的光纤平均灵敏度是未涂覆光纤的175.1%，同时抗冲击性能提高了40.6%。该方法有效平衡了光纤设计中抗冲击性能与测量灵敏度之间的冲突，为通感一体光网络的进一步发展提供了可行的技术路径，具有重要的应用潜力。 |

| The integrated sensing and communication optical network imposes contradictory requirements on optical cables, demanding that they possess strong impact resistance to ensure communication stability and high sensitivity to measure small dynamic strains. In this study, an approach of coating shear thickening materials onto the optical fiber is proposed to address tackle the contradictory demands. By alternately coating shear-thickening fluid (STF) and shear-stiffening gel (SSG) six times, the diameter of the fiber increases from 240.599 μm to 279.032 μm. The experimental results show that the average sensitivity of the shear-thickening material-coated fiber is 175.1% that of the uncoated fiber, while the impact resistance is improved by 40.6%. The method offers a feasible solution to balance the conflicting demands in optical fiber design, may trigger the development and application of integrated sensing and communication optical networks. |
