The United States is preparing draft measures to restrict the import of new **optical transceivers** from China, a key component used to transmit data within data centers. The measures could potentially take effect in 2026.
The move comes amid concerns that Chinese-made equipment could create cybersecurity vulnerabilities, including **data theft, malware installation, or disruption of data center operations**. Data centers are increasingly viewed as critical infrastructure for AI development and computing.
Although the measures are still under consideration, the move highlights growing **U.S.–China technology tensions** that are expanding beyond AI chips to the broader data center supply chain. It could also push operators to seek alternative equipment suppliers in the future.
