Washington Weighs Ban on Chinese Optical Transceivers as AI Data Centers Rely on 30%-40% China-Sourced Power Gear
2 articles · Updated · CNBC · Sep 3
Summary
U.S. officials are moving to curb Chinese inputs in AI data centers, including a reported ban on new Chinese optical transceiver imports as Washington broadens scrutiny from chips to the power stack.
China supplies about 30% of some U.S. transformer and switchgear categories, more than 40% of battery imports, and roughly two-thirds of global optical transceiver unit supply, leaving hyperscalers exposed as AI capacity expands.
Trump's executive order last week declared a national emergency over foreign bulk-power equipment and authorized the Energy Department to block or condition transactions involving components used in the grid and data centers.
Supply risks are already tight: Wood Mackenzie estimates 2026 shortages of 15% for power transformers and 8% for substations, and analysts say replacing Chinese optical volume within 12 to 24 months would be difficult.
U.S. data center capacity is projected to jump from 62 GW in March 2026 to 152 GW by 2030, raising the stakes for a de-risking push that could lift costs even as domestic investment accelerates.
Will the ban on foreign data center components secure U.S. infrastructure, or accidentally cripple the nation's AI expansion?
As AI power demands skyrocket, can Western manufacturers scale up fast enough to prevent a massive grid equipment shortage in 2026?
Could hidden foreign subcomponents in domestic hardware trigger unexpected regulatory shutdowns for major U.S. hyperscalers?

Overview
In 2026, the U.S. government launched aggressive bans on Chinese technology, targeting critical data center components and bulk-power equipment to secure AI and energy infrastructure. These actions, driven by past struggles with removing Huawei and ZTE gear, collided with deep U.S. reliance on Chinese-made grid hardware, batteries, and raw materials. As China retaliated with export controls on key resources like indium phosphide and rare earths, U.S. manufacturers faced soaring costs and severe supply bottlenecks, delaying major AI and clean energy projects. Despite massive investments in domestic production, infrastructure and material shortages continue to challenge America’s push for technological independence.
