FCC drafting ban on Chinese optical transceivers for U.S. data centers; Coherent, Lumentum gain

<cite index="14-2">The Trump administration is drafting a ban on U.S. imports of new models of Chinese data center components, as it seeks to protect the infrastructure that undergirds the AI boom. The Federal Communications Commission is working on the measure to bar imports of new Chinese optical transceivers, which allow data to travel over fiber-optic cables at the speed of light within data centers. Officials hope to publish it this year, when it would take effect.</cite> <cite index="14-2">The move aims to prevent Chinese firms from stealing data, installing malware or disrupting service at U.S. data centers, which house the chips to train and run AI models.</cite>

<cite index="14-3">A U.S. ban on new models of Chinese data center devices would likely hit China's Zhongji Innolight, one of the biggest global sellers of transceivers, which was added to the Pentagon's list of alleged Chinese military-backed companies in June. Innolight has a leading 27% share of the global data center transceiver market, according to Counterpoint Research.</cite> <cite index="14-3">A ban could also raise costs for American cloud firms such as Amazon Web Services, as it may force them to transition to other producers such as U.S.-based Coherent and Lumentum, which stand to benefit from the measure.</cite>

<cite index="16-2">U.S. optical component stocks surged following the Reuters report: Applied Optoelectronics jumped 16%, Coherent gained 13%, Lumentum rose 11%, and Corning climbed 8%.</cite> <cite index="14-4">The FCC has imposed similar curbs on Chinese drones, routers, robots and inverters, as first reported by Reuters. In line with those restrictions, the agency would ban all imports of new transceiver models and then exempt many non-Chinese suppliers from the restrictions.</cite>

For data center operators and cloud infrastructure teams, this signals rising capex pressure: optical transceiver costs will increase as suppliers transition from commodity Chinese components to higher-cost U.S. and allied manufacturers. The ban reflects broadening supply-chain de-coupling in AI infrastructure (optical networking is as critical to large-scale AI compute as memory or accelerators). Watch AWS, Google Cloud, Azure capex guidance for cost absorption and pass-through impacts over the next 2–4 quarters.
