FCC draft on Chinese data-center optical modules puts focus on non-China suppliers and InP bottlenecks
The U.S. Federal Communications Commission is considering restrictions on some new data-center optical modules made by Chinese vendors, but the proposal is still in draft form and several core definitions remain unsettled. The biggest open questions are whether the FCC will define "Chinese origin" by brand, manufacturing location, or component source, whether older models can still enter the U.S., and whether non-Chinese brands using Chinese-made substrates or lasers could still qualify for exemptions. For now, the market is trading the possibility that orders shift toward non-Chinese suppliers. WhiteLine Daily identified Coherent, Lumentum, and Applied Optoelectronics as the most direct potential beneficiaries if U.S. cloud companies continue building AI data centers while Chinese new-model supply faces limits. Marvell and Broadcom could benefit later, but only if demand passes through to DSP, driver-chip, and connectivity layers after module makers actually expand output. Over a longer horizon, the report says the more important constraint may not be module assembly capacity but the supply of indium phosphide, or InP, across substrates, epitaxial wafers, and lasers. AXT, IQE, and Sivers map to different parts of that chain, though each carries a different mix of policy risk and commercial visibility. The report argues that the real test will be the final FCC rule, confirmed customer orders, and whether non-China capacity can scale fast enough.
