FCC weighs ban on new Chinese optical transceivers

The Federal Communications Commission is preparing a regulatory proposal that would block the import of new optical transceiver models made in China into the United States, according to four people familiar with the matter.

The draft measure is framed as a national security step focused on hardware used inside American artificial intelligence infrastructure, where large-scale data processing depends on dense, high-speed networking inside datacenters.

Optical transceivers at the center of the proposal

The planned restriction would apply to optical transceivers, the components that enable high-speed data transmission over fiber-optic networks within datacenters.

Officials involved in the effort are aiming to limit how deeply these devices are integrated into critical systems. The stated concern is that Chinese-manufactured hardware embedded inside key infrastructure could create pathways for data exfiltration, malware installation, or deliberate service disruption.

Market concentration and likely targets

Chinese companies currently hold a majority share of the global optical transceiver market, the sources said, a concentration that could complicate procurement and vendor choices if the restrictions move forward.

Zhongji Innolight was identified as a primary company likely to be affected by the potential import ban, according to the people familiar with the drafting process.

Part of a wider supply-chain security push

The proposed import limits would follow other recent FCC actions involving Chinese technology, including steps focused on Chinese humanoid robotics, according to the same account of the regulator’s direction.

People familiar with the discussions said the broader aim is to harden the domestic AI supply chain and avoid a repeat of earlier patterns of reliance seen with Huawei equipment, where deep infrastructure dependency became difficult to unwind once broadly deployed.

Timing, uncertainty, and possible response from Beijing Officials are seeking to publish the measure within the current calendar year, the sources said. However, they cautioned that the proposal is still in draft form and could be revised significantly or abandoned.

The Chinese embassy has indicated that Beijing may respond with retaliatory steps if the restrictions proceed, citing concerns about the stability of business interests between the two countries.

For datacenter operators and network builders, the immediate question is how quickly any final rule would take effect and which specific “new” models would be covered, details that were not provided by the sources describing the draft.
