The US Federal Communications Commission has finalized updated equipment authorization rules that tighten scrutiny on devices with components from blacklisted Chinese firms but exclude optical transceivers, calming market concerns about a potential ban on these critical data center parts.
- FCC tightens rules on equipment with blacklisted Chinese components
- Chinese optical transceivers excluded from new US ban
- Growth in AI data centers drives optical transceiver demand
What happened
The US Federal Communications Commission (FCC) finalized new equipment authorization regulations in September 2026 that increase oversight of devices containing components from firms on the Covered List, a blacklist of entities deemed national security risks. However, the updated rules explicitly do not ban optical transceivers, key components used in data centers to facilitate high-speed data transmission.
This decision follows earlier market anxiety triggered by reports that previous US administrations had considered blocking Chinese-made optical transceivers from entry. Notably, companies like Zhongji Innolight and Eoptolink Technology saw gains in their stock prices following the announcement, signaling market relief.
Why it matters
Optical transceivers are crucial for enabling the large-scale data transmission needed in artificial intelligence (AI) infrastructure, where China-based manufacturers dominate the global market. As AI workloads grow, data center interconnects increasingly rely on optical technologies due to electrical connection limitations like bandwidth, distance, and power consumption.
The market for optical interconnects is rapidly expanding, projected to grow from $24.8 billion in 2025 to $111 billion by 2030. Data centers are adopting newer, faster optical transceiver generations on accelerated cycles, reflecting the strategic importance of these components in competitive AI cluster development.
What to watch next
Industry players and regulators will closely monitor the evolving US-China technology competition, particularly developments in optical transceiver technology architectures. Chinese companies favor near-packaged optics (NPO), leveraging mature supply chains, while US firms push for co-packaged optics (CPO) integration to optimize performance.
Market growth projections suggest that shipments of 800Gbps and emerging 1.6Tbps optical transceivers will continue to surge through 2027, with the 3.2Tbps generation on the horizon. How US regulators address related security concerns without disrupting this vital supply chain will be critical for the future of AI hardware development.
