On October 19, 2026, Mr. Liang Lyu, Dr. Shao-Qun Lin from CNERC-Rail (HK Branch), Dr. Yang Lu and Mr. He-Tao Huang from HZRI visited the Zhuyong Expressway in Wenzhou. Members discussed with Dr. Yu-Sen Chen, Chief Scientist of Zhejiang Communications Investment Group, and his team at Wenzhou Expressway Management Center on the field test layout and test items for DAS. Afterwards, members conducted an on-site survey at the test section to inspect the existing test arrangement, including the 1.8 km sensing fiber deployed along the pavement and the locations of the existing communication optical cables. Data acquisition was performed on the two types of optical fibers on site. The implementation plan will be optimized after preliminary data analysis.
