Bipartisan senators Dave McCormick and John Cornyn introduced a bill on Friday that would bar the U.S. government from purchasing optical transceivers manufactured by Chinese companies Eoptolink and Zhongji Innolight for use in sensitive systems, including AI data‑center infrastructure. The legislation would initially target those two firms and give the secretaries of Commerce and Defense the authority to add additional manufacturers to a restricted list. If passed, agencies would have five years to comply with the new procurement rules.
The legislation was introduced by Republican Senator Dave McCormick of West Virginia and Republican Senator John Cornyn of Texas, both emphasizing the need to eliminate reliance on foreign hardware for critical government communications. The bill specifically names Eoptolink and Zhongji Innolight, companies previously flagged for alleged ties to China’s military, as prohibited suppliers for federal procurement of optical transceivers used in AI‑related systems.
Under the proposed law, the secretaries of Commerce and Defense would be empowered to expand the list of prohibited manufacturers, allowing the government to quickly to emerging security threats. The bill provides a five‑year compliance window for agencies to replace existing Chinese‑sourced equipment with domestically produced alternatives.
Industry reaction has been mixed. The Information Technology Industry Council, representing major tech firms, sent a letter to the Federal Communications Commission urging it not to place optical transceivers on a trade blacklist, warning that current U.S. suppliers lack the scale to fully replace Chinese output. A report from the Foundation for American Innovation notes that while companies like Coherent Corp. and Lumentum Holdings produce comparable devices, they cannot yet meet the volume demanded by expanding data‑center projects.

Optical transceivers are a core component of fiber‑optic networks that move the massive data streams required by modern AI workloads. By restricting Chinese‑made devices, the bill seeks to reduce the risk that Beijing could embed hardware‑level vulnerabilities or otherwise interfere with U.S. AI tools and cloud services. At the same time, industry groups warn that the limited domestic supply of comparable transceivers could slow data‑center expansion and hamper the United States’ ability to keep pace with China’s rapid AI infrastructure build‑out. The measure therefore sits at the intersection of national‑security policy and the practical supply‑chain realities of the AI ecosystem.
Optical transceivers translate electrical signals into light for fiber‑optic transmission, a function that has become indispensable for AI workloads that require low‑, high‑bandwidth data movement. Any compromise in these components could enable espionage, data tampering, or denial‑of‑service attacks on government AI systems.
The bill reflects a broader U.S. strategy to harden the AI supply chain against perceived Chinese influence, aligning with diplomatic efforts such as the recent framework for notifying each other of AI‑related incidents. However, the limited domestic production capacity raises concerns that the policy could unintentionally slow U.S. AI development by creating bottlenecks in data‑center construction.
By targeting specific manufacturers rather than an entire category of hardware, the legislation attempts to balance security with supply‑chain continuity. The five‑year transition period is intended to give U.S. firms time to scale up production, but the effectiveness of that timeline remains uncertain.

Key indicators to monitor include the bill’s progress through the Senate and House, any amendments that broaden or narrow the scope, and the response of U.S. optical‑component manufacturers such as Coherent Corp. and Lumentum Holdings. Watch for statements from the Commerce and Defense secretaries about potential additions to the restricted list, as well as any legal challenges from the targeted Chinese firms. Finally, observe how the move influences broader U.S.–China AI dialogue and whether it prompts similar restrictions on other networking hardware.
Legislative trajectory: committee hearings, amendments, and eventual votes in both chambers will determine whether the bill becomes law.
Regulatory actions: how quickly the Commerce and Defense secretaries act to add other firms to the restricted list, and whether they issue guidance that expands the scope beyond the two named companies.
Industry response: announcements from Coherent Corp., Lumentum Holdings, and other U.S. manufacturers about capacity expansions, as well as any legal challenges filed by Eoptolink or Zhongji Innolight.
Geopolitical ripple effects: whether the measure prompts reciprocal Chinese restrictions on U.S. networking equipment, and how it influences ongoing U.S.–China AI cooperation frameworks.
