The U.S. government is reportedly drafting a ban on imports of new Chinese data center components to protect critical infrastructure supporting artificial intelligence (AI) development, according to a report cited by China News Service on August 4.
The Federal Communications Commission (FCC), which oversees the U.S. telecom sector, is developing measures to restrict imports of new Chinese optical transceiver modules, though sources indicate the FCC may still modify or shelve these restrictions.
China's embassy in Washington responded by urging the U.S. to "listen to the objective and rational voices of the business community from both countries" and stop smearing Chinese companies or threatening sanctions. It added that "China will take all necessary measures to respond to any action that seriously damages its interests."
Industry analysts believe a strict ban on Chinese optical modules is unlikely, as the U.S. AI buildout depends heavily on Chinese suppliers. Of the world's top 10 optical module manufacturers, seven are Chinese, with Chinese companies accounting for 70% of shipments for high-speed 800G and 1.6T modules. U.S. manufacturers lack sufficient capacity and technological advancement, and major U.S. cloud providers accelerating AI infrastructure would face delays without Chinese modules. Historically, strict import bans on such products have been rare.
A market analyst told The Paper that similar reports have surfaced multiple times before, making it difficult to verify their accuracy. "Even if the news is true, history suggests the impact will be manageable," they said, noting that after tariff increases in 2025, optical modules were among the first products exempted due to opposition from U.S. cloud firms. Any future policy would likely include broad exemptions.
According to an analyst cited in the report, the current information suggests the FCC's focus may be on product certification and testing rules, not an outright ban. "If the rules are finalized, various solutions will emerge to comply," they said.
Guotai Junan Securities' communications research team noted that no official information or details have been released, and similar rumors have circulated before. They urged reliance on government or industry sources. The team added that the optical communications ecosystem is highly complex and globalized, with both North American demand-side CSPs and Chinese supply-side module and component makers having prepared for geopolitical risks over the past five to six years, including policy responses, capital deployment, and production capacity diversification.
"The optical communications industry relies heavily on a globalized ecosystem. Not only do Chinese companies benefit, but key U.S. chip and component suppliers take significant profits upstream, while downstream CSPs gain critical support," Guotai Junan stated. "A blanket ban would only harm globalization, so such an outcome is nearly impossible."
The firm also highlighted that Chinese companies are deeply involved in traditional pluggable products and are collaboratively developing next-generation NPO and Coherent lite products with North American cloud giants, a process with long development cycles and high barriers that cannot be easily replicated.
