The Trump administration is preparing new restrictions that would prohibit imports of new Chinese-made optical transceivers used in US data centers, escalating Washington's campaign to secure the artificial intelligence infrastructure supply chain against potential national security threats.
According to an exclusive Reuters report published on August 4, 2026, the Federal Communications Commission (FCC) is drafting a measure that would block imports of new models of Chinese optical transceivers. These networking components transmit data through fiber-optic cables at extremely high speeds inside the data centers that power AI training and cloud computing.

What Are Optical Transceivers and Why Do They Matter?
Optical transceivers are small but essential components of modern data centers, enabling ultra-fast communication between thousands of servers and AI processors. As AI models grow larger and training clusters expand to tens of thousands of GPUs, the networking equipment that keeps these systems connected has become a focal point of national security scrutiny.
The proposed ban represents a significant widening of the US technology restrictions on China. While previous measures have largely targeted advanced semiconductors and AI chips, this proposal extends into the networking equipment layer — the hardware that moves data between processors at the speed of light.
US officials are increasingly scrutinizing every layer of the hardware stack, treating AI infrastructure as critical infrastructure comparable to telecommunications networks or power grids. The proposed restrictions are intended to reduce the risk that Chinese-made networking equipment could be used to steal sensitive data, introduce malicious software, or disrupt the operation of facilities that host advanced AI models.
A Proposal Still Under Development
The proposal, which Reuters described as not previously reported, is expected to be published later this year if approved. However, the sources cited by Reuters cautioned that the FCC could still revise or abandon the plan before implementation.
Multiple major outlets corroborated the report, including The Guardian, The Japan Times, Bloomberg, and The Information, all of which cited the same Reuters exclusive. China's AI hardware stocks slumped following the news.
The move reflects the Trump administration's broader strategy of preventing Chinese technology from becoming deeply embedded in America's AI supply chain, where officials fear it could create long-term national security vulnerabilities.
Expert Reactions and Industry Concerns
"Transceivers definitely pose a risk," said Divyansh Kaushik, an AI policy expert at Beacon Global Strategies, in comments reported by Reuters and cited across multiple outlets. "As the data center buildout scales up, you want to make sure the data center supply chain is secure from the get-go."
The timing of the proposed ban comes amid an unprecedented wave of investment in AI infrastructure. Companies including Amazon, Google, Microsoft, Meta, and a growing number of AI cloud startups are pouring hundreds of billions of dollars into new data centers to meet surging demand for AI compute. The global optical transceiver market, dominated by Chinese manufacturers, is projected to grow substantially as these facilities come online.
Industry analysts note that restricting Chinese transceiver imports could increase costs and slow data center construction timelines in the short term, as alternative suppliers in the United States, Taiwan, and other allied nations scale up production. However, proponents argue that supply chain security must be prioritized given the strategic importance of AI infrastructure.
China's Response
China sharply criticized the reported proposal. A spokesperson for the Chinese embassy in Washington urged the United States to "heed the objective and rational voices of the business communities in both countries" and to "stop smearing Chinese companies and threatening them with sanctions."
The embassy added a pointed warning: "China will take all necessary measures in response to any action that causes material harm to its interests."
The proposed transceiver ban is the latest in a series of escalating US measures targeting Chinese technology in the AI sector. Earlier in 2026, the FCC banned new Chinese humanoid robots over national security concerns, and the administration has continued to tighten export controls on advanced AI chips.
What Comes Next
If the FCC proceeds with the draft measure, it would mark one of the most expansive attempts yet to decouple the US data center supply chain from Chinese manufacturers. The proposal's final scope — whether it applies to all Chinese transceivers or only new models, and how it defines "Chinese-made" — will be closely watched by the AI industry, hardware suppliers, and international trade partners.
For an industry already grappling with massive capital expenditures and supply chain bottlenecks, the prospect of another layer of hardware restrictions adds further uncertainty to the AI infrastructure buildout that shows no signs of slowing down.
