Shares of China’s leading optical-module makers clawed back early losses on Wednesday after analysts downplayed the impact of proposed US restrictions that could block the firms from future American AI data centres. They noted that the rules would likely leave current supply chains intact and face significant hurdles because of America’s heavy reliance on Chinese manufacturing. Zhongji Innolight ended the day down 7.3 per cent and 6.7 per cent in Shenzhen and Hong Kong, respectively, while Eoptolink Technology dropped 5.3 per cent and Suzhou TFC Optical Communication gained 2.3 per cent in Shenzhen. In contrast, their US rivals surged on Tuesday, with Coherent closing 12.4 per cent higher and Lumentum gaining 8.9 per cent. Zhongji Innolight, Eoptolink, and Suzhou TFC did not immediately respond to requests for comment on Wednesday.
