Fiber and cable are the physical links between and inside data centers, and YOFC is one of China's largest producers; but most of its business is telecom and broadband networks, so AI is not yet its primary economic driver.
Sells fiber preforms, fiber, cable and related products to telecom carriers, network builders and data-center operators in China and more than 100 other countries and regions.
