The draft would block Chinese optical transceivers, the fiber optic parts that move data between AI chips. Officials cite the slow, expensive removal of Huawei telecom gear as the rationale.
The FCC is drafting a ban on imports of new Chinese optical transceivers, the small fiber-optic components that shuttle data between chips inside AI data centers, and officials hope to publish the restriction this year. The move tests a supply-chain doctrine hawks have been pushing since the Huawei rip-and-replace: block Chinese components at the border before they entrench, rather than pay to remove them later. Reuters reported the draft, by Alexandra Alper, on Aug. 4.
The mechanism is the FCC's Covered List authority, the same tool the commission used about four days earlier to bar new Chinese humanoid robots and certain inverters from the US market. According to Reuters, the draft would cover optical transceivers plus any other new-model Chinese data-center components in scope. The stated rationale, per four people familiar with the matter, is preventing Chinese firms from stealing data, installing malware, or disrupting the US data centers that house AI training and inference chips.
Zhongji Innolight, one of the world's largest sellers of optical transceivers, is the most exposed vendor. The Pentagon added Innolight to its list of alleged Chinese military-backed companies in June, and Counterpoint Research puts its share of the global transceiver market at roughly 27 percent. US rivals Lumentum, Coherent, and Applied Optoelectronics each saw share-price moves on the news. The White House and FCC declined to comment.
The doctrine is the Huawei template in reverse. Huawei's telecom gear embedded itself in US networks, and removing it has been slow, expensive, and incomplete. Transceivers sit at the physical layer connecting GPUs and switches in the AI buildout, and the goal is to block them at the border before that entrenchment happens. "Transceivers definitely pose a risk," Beacon Global Strategies' Divyansh Kaushik told Reuters. "As the data center buildout scales up, you want to make sure the data center supply chain is secure from the get-go."
Reuters has already documented a reversal. In February 2026, the Commerce Department had mothballed earlier data-center equipment restrictions after the October 2025 US–China trade détente, and the FCC's current draft has no public commitment to timing or coverage. The Chinese embassy in Washington, asked for comment, warned that Beijing "will take all necessary measures in response to any action that causes material harm to its interests" and urged the US to "stop smearing Chinese companies and threatening them with sanctions." That is a deliberate counter-voice: a public restatement of the diplomatic cost of the doctrine the FCC is now testing.
Reuters' sources say the FCC could still modify or shelve the measure, and the draft remains unpublished. Two practical questions follow. Can the policy survive the live trade détente that killed the prior round? Can a roughly 27-percent-concentrated Chinese supplier be replaced at buildout speed without materially raising US data-center costs? The wire does not answer the second, and public evidence does not yet allow a confident one. Lumentum, Coherent, and Applied Optoelectronics all sell competing transceivers; their share-price moves show the market is pricing the change, not the outcome.
The next date that matters is when the FCC publishes the draft, if it does. Until then, the doctrine is in motion, not in force.
