❯ Trump Administration Drafts Ban on Chinese Optical Modules; Texas Freezes New Data Center Grid Approvals Same Day

TWIN GATESThe U.S. compute supply was squeezed in two places on the same day: the Trump administration is drafting a rule to ban imports of Chinese-made optical modules, and has handed it to the Federal Communications Commission to advance; officials want it finalized and enforced by year-end. On the same day, Texas Governor Abbott announced a freeze on grid-connection approvals for new data centers, to be lifted only after regulators complete an audit. The former blocks components; the latter blocks power.

TWO SIDESOn the optical module side, Innolight holds roughly a 27% share of the global data center optical module market, with 90% of revenue coming from outside China, and was added to the Pentagon’s Chinese military-company list in June. The rule would first prohibit imports of all new models, then grant case-by-case exemptions to non-Chinese suppliers. After the news, Lumentum, Coherent, and Applied Optoelectronics rose 7%, 11%, and 18%, respectively, but industry insiders caution that these suppliers cannot pick up the slack immediately; a replacement cycle would slow data center construction and severely delay near-package optics adoption. The rule is still a draft, and the FCC could revise or abandon it at any time. The numbers on the Texas side are more alarming: grid operator ERCOT has about 474 gigawatts of pending new-load applications, more than five times the state’s all-time peak load, about 90% of it from data centers. The governor demanded itemized disclosure of tax incentives, power consumption and self-generation, water and cooling plans, and actual owners.

TWIN SQUEEZEFor the past year, the default assumption was that compute expansion just needed money to get built. Now both ends are tightening: components are constrained by export controls, and power by local permitting — and neither is something more money can buy immediately. Texas project developers now have to compile audit materials before they can even discuss construction timelines, and a batch of capacity that had been scheduled for next year is being pushed back. Procurement heads also need to prepare the replacement list for optical modules ahead of time — wait for the rule to be finalized and lead times will already be gone.

▪ SIGNALThe bottleneck for compute expansion is shifting from chip supply to grid interconnection and customs.
