The Trump administration is drafting a ban on imports of new Chinese-made data center components, and the FCC is separately preparing a rule targeting Chinese optical transceivers that officials want finalized this year. The move threatens Zhongji Innolight, which holds 27% of the global transceiver market and could raise costs for US cloud providers like AWS.
What Does the Draft Ban Cover, and When Might It Take Effect?
The Trump administration is drafting a rule to ban imports of new Chinese-made data center components, while the FCC is separately preparing a measure against Chinese optical transceiversCITE:E1.
Reuters reported on August 4 that four people familiar with the matter said the administration is drafting a ban on importing new-generation Chinese data center components to protect infrastructure underpinning the AI boomCITE:E1. A second account, also sourced to four people familiar with the matter, described the same draft ban on newly manufactured Chinese data center partsCITE:E11. Specifically, the Federal Communications Commission (FCC) is drafting a measure to block imports of new Chinese-made optical transceivers — devices that move data through fiber-optic cable at the speed of light inside data centersCITE:E2. US officials want the rule announced and in effect this yearCITE:E12.
Why Ban These Components? What Security Concerns Are Cited?
Officials say Chinese-made transceivers could let Chinese companies steal data, insert malware, or disrupt operations at US data centersCITE:E3.
The previously undisclosed effort is meant to prevent Chinese companies from stealing data, planting malicious code, or interfering with the operation of US data centers, which house the chips used to train and run AI modelsCITE:E13. Divyansh Kaushik, an AI policy expert at Beacon Global Strategies, a Washington-based security advisory firm, said transceivers "certainly pose a risk" and that as data centers scale up, supply chains need to be secured "from the start"CITE:E5CITE:E15.
How Does This Fit Washington's Broader Supply-Chain Defense Against China?
China hawks in the administration are trying to avoid repeating the outcome with Huawei, whose telecom gear became too embedded in US infrastructure to remove easilyCITE:E6.
Huawei was hit with severe US sanctions, but its equipment was already woven so deeply into American infrastructure that replacing it proved slow, costly, and never fully completeCITE:E6. The FCC has already imposed similar import restrictions on Chinese-made drones, routers, robots, and inverters, making the transceiver measure the latest in a pattern rather than an isolated moveCITE:E10.
Why Is Zhongji Innolight in the Crosshairs?
Zhongji Innolight (中際旭創), the world's largest data center transceiver supplier, was added to a Pentagon list of companies linked to China's military in JuneCITE:E7.
One report identified the listing body as the PentagonCITE:E7, while another described it as the US War DepartmentCITE:E17 — both referring to the June designation that observers say could foreshadow tougher sanctions aheadCITE:E7CITE:E17. Zhongji Innolight did not respond to a request for commentCITE:E17.
| Metric | Value | Citation |
|---|
| Global data center transceiver market share | 27% | CITE:E9 |
| Share of revenue from outside China | 90% | CITE:E9 |
| Added to Pentagon's China military-linked list | June 2026 | CITE:E7CITE:E17 |
According to Counterpoint Research data, Zhongji Innolight controls 27% of the global data center transceiver market, and 90% of its revenue comes from outside ChinaCITE:E9. Coherent and Lumentum, the two US-based alternatives, do not have sales volumes large enough to replace Chinese suppliers at that scaleCITE:E9.
What Economic Fallout Could the Ban Have for US Cloud Providers?
The ban could raise costs for US cloud providers such as AWS by pushing them toward domestic suppliers Coherent and LumentumCITE:E8.
Amazon Web Services (AWS) and similar companies could face higher costs because they may be forced to shift to US-based manufacturers Coherent and LumentumCITE:E18, which stand to benefit from the banCITE:E8CITE:E18. As noted above, those two suppliers' current sales scale is not sufficient to fully substitute for Chinese-made transceiversCITE:E9.
Could the Ban Be Changed or Shelved, and How Have Parties Responded?
Sources say the FCC could still modify or shelve the proposed restriction before it takes effectCITE:E4.
People familiar with the matter, speaking on condition of anonymity given the sensitivity of the issue, said the FCC may revise or set aside the limit, even as it represents the administration's latest attempt to restrict Chinese technology from penetrating leading-edge US industriesCITE:E14. The White House and the FCC did not respond to requests for commentCITE:E16. China's embassy in Washington said Beijing urges the US to "heed the objective and rational voices of the business communities in both countries" and to "stop smearing Chinese companies and threatening sanctions," adding that China "will take all necessary measures to respond to any action that substantially harms its interests"CITE:E16.
What Does This Mean?
The measure is still a draft that the FCC itself could modify or shelveCITE:E4CITE:E14, yet its anticipated impact is already concrete: Zhongji Innolight, blacklisted by the Pentagon in June and holding 27% of the global transceiver market, sits opposite AWS and other cloud operators who would absorb higher costs shifting to Coherent and LumentumCITE:E7CITE:E9CITE:E8. That gap between an unfinished rule and its already-mapped winners and losers runs alongside China's warning that it will respond to any action harming its interestsCITE:E16, while Washington's stated aim — avoiding a repeat of the Huawei entanglement — suggests officials are trying to act before, not after, the supply chain becomes hard to unwindCITE:E6.
