US FCC to ban Chinese optical transceivers by end of 2026

The U.S. Federal Communications Commission is drafting a rule to ban imports of Chinese-made optical transceivers by the end of 2026, citing data-center security risks. The planned restriction targets critical components used to convert electrical data to light in fiber-optic networks. China has vowed to respond if necessary.
The Proposed Ban
The U.S. Federal Communications Commission is drafting a rule to ban imports of Chinese optical transceivers from U.S. data centers, aiming for implementation before 2026 ends. The administration fears the components could enable data theft, malware insertion, or operational disruption. China’s Zhongji Innolight holds a 27% global market share, dwarfing U.S.-based Lumentum, Coherent, and Apple Optoelectronics. Lumentum and Coherent, however, are poised to benefit if the ban proceeds, according to Wccftech. The FCC seeks to avoid the costly Huawei-style replacement scenario by acting before Chinese transceivers become deeply embedded.
Pattern of Restrictions
The transceiver ban extends a series of FCC actions against Chinese-linked technology. Drones were restricted in December 2025, routers in April 2026, and advanced robots weighing over 4.4 pounds with 200-kbps connectivity in July 2026. The robot ban unexpectedly covered vacuum cleaners from iRobot, Roborock, Ecovacs, Dreame, and Xiaomi, all Chinese-owned. Conditional waivers have been issued, including for Netgear and Amazon through October 2027. TP-Link’s exemption request from April remains unresolved. AI policy expert Divyansh Kaushik of Beacon Global Strategies emphasized that transceivers pose a risk as data center buildout scales.
What's Next
The FCC is expected to publish the ruling in the coming months to meet the year-end deadline. Whether the ban will provoke Chinese retaliation or trigger exemption requests from major U.S. cloud providers remains uncertain.
