The U.S. government is advancing a crypto ban targeting Chinese optical transceivers as part of a broader CFT strategy to secure AI infrastructure. The proposed rule, currently under FCC review, would prohibit the import of Chinese-made transceivers used in data centers. These components are essential for high-speed data transmission in AI systems. Inphi, a major Chinese supplier, holds 27% of the global market. U.S. companies such as Coherent and Lumentum lack the capacity to fully replace Chinese production. The ban, expected by 2026, could increase costs for cloud providers like Amazon. This move signals an expanding CFT-driven effort to control AI supply chains, including optical modules and server components.

Huo Xing Finance reports that on August 5, the U.S. government is drafting a new ban to prohibit the import of newly developed optical transceivers manufactured in China, aiming to strengthen control over the AI infrastructure supply chain. Sources familiar with the matter reveal that the Federal Communications Commission (FCC) is formulating related restrictions, and U.S. officials plan to announce and implement the ban within 2026. However, the measure remains under discussion and may be modified or shelved in the future. Optical transceivers are core components within optical modules, responsible for converting electrical signals to optical signals and back, and are critical hardware for high-speed data transmission in AI data centers. If implemented, the ban could disrupt the global optical module supply chain. The report notes that InnoLight Technology, a leading global supplier of optical modules, may be significantly impacted. According to Counterpoint Research data, InnoLight currently holds approximately 27% of the global data center optical transceiver market. A previous report by the U.S. Innovation Foundation stated that domestic U.S. suppliers Coherent and Lumentum lack sufficient production capacity to fully replace Chinese suppliers. Meanwhile, the measure could also increase costs for U.S. cloud service providers. Major cloud companies such as Amazon may need to shift procurement of optical communication equipment to U.S.-based suppliers to meet the expanding demands of AI data centers. Market analysts view the U.S. restriction on importing Chinese optical communication components as an indication that competition in AI infrastructure is extending beyond chips to other critical segments of the data center supply chain, including optical modules, power equipment, and server components.
