FCC proposes import ban on Chinese optical transceivers — blockade targets key AI interconnects as China holds 56% global market share
The FCC is drafting a proposal that would expand its list of equipment and services covered by the Secure Networks Act to include imports of new-model optical transceivers manufactured in China.
The Federal Communications Commission (FCC) is planning to propose a ban on the import of optical transceivers manufactured in China, as reported by TrendForce. This proposed restriction could significantly impact the hyperscaler AI companies, as optical interconnect technologies are seen as crucial for advancing AI performance, latency, and efficiency.
Chinese manufacturers currently hold around 56% of the global manufacturing capacity for this key technology, which will likely influence the U.S. administration's decision to decouple its reliance on this supply chain and strengthen alternatives, including domestic and international sources. The potential ban may eventually lead to the FCC refusing to authorize Chinese networking hardware, following recent bans on foreign-manufactured routers and advanced robotics.
The AI industry's rapid growth has faced various bottlenecks, with optical interconnects being a key area where China has a strong presence. These interconnects replace the limitations of copper wiring, increasing bandwidth, reducing latency, and lowering power consumption. However, China controls a significant portion of the global optical interconnect supply chain, particularly due to its monopoly on indium phosphide, a crucial raw material. As a result, the U.S. may need to take strong measures to address this dependency.
