Zhongji Innolight Responds to Rumors of Potential US Ban on Chinese Optical Modules
Chinese optical module manufacturer Zhongji Innolight responded to market rumors of a potential US FCC import ban on Chinese data center components, including optical modules. The company stated that the FCC has not yet released any official restrictive documents and declined to comment further on the potential impact. Optical modules are critical components in high-speed data centers, and any US ban could disrupt the global AI hardware supply chain, especially for major US tech firms relying on Chinese suppliers. Zhongji Innolight is a leading player in this sector, with high-speed optical modules accounting for nearly 95% of its Q1 2026 revenue. Despite the geopolitical uncertainties, Zhongji Innolight recently completed a dual listing in Hong Kong, raising approximately 53.41 billion HKD in the city's largest IPO of the year. The company's Q1 2026 revenue surged by 192.12% year-on-year to 19.496 billion RMB, driven by massive demand for AI infrastructure.
## BACKGROUND
An optical module (or optical transceiver) is a hot-pluggable device that converts electrical signals into optical signals for high-bandwidth data transmission. They are essential for connecting servers within modern AI data centers. As US-China tech tensions escalate, the US government has increasingly targeted Chinese hardware components to secure its telecommunications and computing infrastructure.
