US Lawmakers Move to Ban Chinese Optical Transceivers From Government AI Data Centers

Bipartisan Legislation Targets Chinese Components in Government AI Systems

A bipartisan group of US lawmakers introduced legislation on Friday to bar the federal government from using Chinese-made optical transceivers in sensitive government systems1

1

. The bill, sponsored by Republicans John Cornyn and Dave McCormick alongside Democrats John Fetterman and Ruben Gallego, specifically targets components manufactured by China's Eoptolink and Zhongji Innolight2

2

. These optical transceivers allow data to travel over fiber-optic cables at the speed of light and sit at the heart of the US AI infrastructure rollout, with some AI data centers requiring millions of them1

National Security Concerns Drive Restrictions on Chinese Datacenter Tech

Supporters of the US legislation argue that Chinese-made optical transceivers could be exploited by Beijing to disrupt access to US AI tools and cloud services3

3

. Senator McCormick stated, "We shouldn't rely on China for technologies that are essential to our national security," while Cornyn emphasized that "critical government communication and information systems must be safe, reliable, and free of any foreign interference"1

1

. The legislation adds pressure on Chinese optical transceiver makers, which currently dominate the market for parts critical to AI data centers2

2

. Notably, Zhongji Innolight has already been added to a Pentagon list of alleged Chinese military-backed companies4

Industry Warns of Supply Chain Disruptions and AI Competitiveness Risks

The US technology industry has raised concerns that restricting Chinese suppliers could slow the US AI infrastructure buildout and potentially cede ground to China in geopolitical competition1

1

. The Information Technology Industry Council sent a letter to the FCC on August 13 urging the telecoms watchdog to "refrain from adding optical transceivers" to a trade blacklist, emphasizing potential supply disruptions that could affect data center deployment and U.S. AI leadership2

2

. US-based firms Coherent and Lumentum sell competitive technology but currently lack the scale to replace Chinese vendors, according to a Foundation for American Innovation report3

3

. This capacity gap presents a significant challenge as hyperscalers scramble to find alternative suppliers amid surging computing demand.

Implementation Timeline and Regulatory Authority

If approved, the legislation would give the government five years to comply with the restrictions on Chinese-made optical transceivers in sensitive government systems4

4

. The bill grants the Secretaries of Commerce and Defense authority to add additional companies to the restricted list beyond Eoptolink and Zhongji Innolight1

1

. This provision suggests lawmakers anticipate the need for flexibility as US-China tensions evolve and new security concerns emerge around foreign interference in critical infrastructure. The extended compliance period acknowledges the practical challenges of transitioning away from Chinese datacenter tech while domestic manufacturers scale production capacity to meet demand from AI data centers across government and commercial sectors.
