The Chinese Parts in US Data Centers and Why Trump Wants to Ban Them
Analysts warn of potential data collection, disruption and supply chain risks of depending on China for optical transceivers.
The Trump administration is reportedly planning to ban a Chinese-made component from data centers to address concerns over security risks to America's AI infrastructure, according to four sources familiar with the matter cited by Reuters. The targeted component is optical transceivers, which are essential for transmitting data over fiber-optic cables inside sprawling data centers.
The Federal Communications Commission may modify or abandon the proposed restrictions before the end of 2026. This move comes as the U.S.-China AI competition escalates beyond chips and algorithms, now extending to the infrastructure needed to support them. The U.S. has already tightened export controls on advanced AI chips to China in an attempt to slow the development of technologies that could provide an advantage to the People’s Liberation Army and undermine America's technological edge.
Intelligence agencies indicate that Chinese state-backed hackers have infiltrated critical American infrastructure and consumer devices, posing a risk of intelligence collection or system disruption during future crises. Adam Segal, director of the Council on Foreign Relations' Digital and Cyberspace Policy Program, expressed concerns about the potential data collection, disruption, and long-term dependence on Chinese suppliers.
Optical transceivers are crucial components in modern communications networks, converting electrical signals into light pulses for data transmission, and are increasingly vital in AI data centers. President Trump's administration is concerned that reliance on Chinese suppliers for such components could leave the country vulnerable if China were to cut off supplies.
Dmitri Alperovitch, chairman of Silverado Policy Accelerator, argued that banning these imports would strengthen the AI supply chain and reduce China's ability to weaponize its dominance over components like rare earth minerals, which are critical for various industries. However, analysts warn that such a ban could raise costs and uncertainty for major tech companies, potentially impacting AI development in the short term.
China has strongly criticized U.S. restrictions on advanced technology exports, alleging that they distort global supply chains and strain bilateral relations.
