• The Trump administration is drafting a Federal Communications Commission rule to ban imports of new Chinese optical transceivers used in AI data centers, citing national security risks.
  • The move could disrupt supply chains for major cloud providers like AWS, potentially increasing costs, while benefiting U.S. manufacturers such as Coherent (COHR) and Lumentum (LITE).
  • Chinese supplier Zhongji Innolight would be significantly impacted, as the proposed rule aims to prevent espionage, malware, and other supply chain threats.

Regulatory Push and Industry Impact

According to sources familiar with the matter, the proposed rule, expected to be unveiled this year, would prohibit the import of new optical transceivers made by Chinese companies. These components are critical for high-speed data transmission in AI data centers, which rely heavily on efficient and secure networking hardware.

“This is a targeted measure to protect U.S. digital infrastructure from potential cyber threats embedded in foreign-made components,” said a former FCC official with knowledge of the discussions. The rule reflects growing bipartisan concern over the security of the U.S. tech supply chain, especially in light of escalating tensions with China over technology and trade.

Zhongji Innolight, a leading Chinese supplier of optical transceivers, stands to lose significant market share in the U.S. The company has been a major player in the global data center market, but this ban would effectively bar it from selling new products in the U.S. market, forcing it to pivot to other regions. In contrast, U.S.-based companies like Coherent and Lumentum are expected to see increased demand as cloud providers and data center operators seek alternative sources.

Costs and Cloud Providers

While the rule aims to bolster national security, it could also raise costs for cloud providers such as AWS, Microsoft Azure, and Google Cloud, which are among the largest buyers of these components. These companies have been aggressively expanding their AI infrastructure, and any disruption in the supply of optical transceivers could delay projects and increase capex. One industry analyst noted, “Hyperscalers will need to reassess their supply chain strategies, potentially expediting qualification of new suppliers or redesigning systems to accommodate different components.” The added cost could eventually trickle down to consumers and businesses that rely on cloud services.

Despite these concerns, the administration appears committed to the ban, viewing it as a necessary step to safeguard critical infrastructure. Similar restrictions have already been placed on other Chinese telecom equipment, and this proposal extends those efforts to data center components.

Broader Implications

The move is part of a broader trend of decoupling between the U.S. and China in technology sectors. It also aligns with recent initiatives to boost domestic manufacturing of semiconductors and other key technologies. The proposed rule is now open for public comment, and the FCC is expected to finalize it later this year.

While the ban focuses on new imports, existing equipment already installed in U.S. data centers would likely be unaffected, but operators may face pressure to eventually replace these components. Meanwhile, the global optical transceiver market is set for a shakeup, with U.S. manufacturers poised to gain a competitive edge.
