Bipartisan US Bill Seeks to Purge Chinese-Made Tech From Sensitive Government Networks

.

A bipartisan group of US senators introduced a bill on Friday that would block the federal government from installing Chinese-made data transmission components in its most sensitive computer systems. The legislation targets optical transceivers, small devices that move enormous amounts of data through fiber-optic cables at the speed of light. They are considered essential building blocks of the artificial intelligence (AI) boom.

The bill is called the Securing National Security Systems from Chinese Optical Transceivers Act. It was introduced by Republican Senators John Cornyn of Texas and Dave McCormick of Pennsylvania, together with Democratic Senators John Fetterman of Pennsylvania and Ruben Gallego of Arizona.

​

What the Bill Would Actually Do

Optical transceivers sit inside data centers and convert electrical signals into pulses of light and back again. A single large AI data center can require millions of these small modules to keep information flowing between servers. Without them, modern cloud computing and AI systems simply cannot function.

The proposed law would name two Chinese manufacturers, Eoptolink and Zhongji Innolight, and bar their transceivers from the federal government's most sensitive national security networks. If passed, the government would get five years to remove any existing Chinese-made units already in use. The Secretaries of Commerce and Defense would also gain the power to add further Chinese companies to the restricted list later on.

​

Why Lawmakers Are Worried

Senator McCormick argued that the United States should not depend on China for technology tied to national security. Senator Cornyn separately warned that Chinese-made equipment in government communication systems creates a risk of foreign interference, according to a statement reported by Reuters.

The concern is not new. Zhongji Innolight, one of the two companies named in the bill, was added to a Pentagon list of alleged Chinese military-linked companies back in June. Lawmakers and security officials fear that because transceivers can carry reprogrammable firmware, a compromised device could theoretically be used to disrupt access to US cloud services or AI systems, or even to intercept data flowing through them.

​

A Dominant Chinese Market Position

Part of what makes this a difficult problem is scale. Chinese manufacturers, led by Zhongji Innolight and Eoptolink, control a large share of the global optical transceiver market. Two US-based competitors, Coherent and Lumentum, make comparable technology but currently lack the manufacturing capacity to replace Chinese suppliers on short notice, according to a report by the Foundation for American Innovation.

That imbalance has made the US tech industry uneasy about moving too fast. The Information Technology Industry Council, a Washington lobbying group representing major tech firms, wrote to the Federal Communications Commission (FCC) in August urging it not to add optical transceivers to a trade blacklist. The group warned that supply disruptions could slow down American data center construction and hand China an advantage in the broader AI race.

Neither Innolight, Eoptolink, nor the Chinese Embassy in Washington responded to requests for comment on the new Senate bill, Reuters reported. Coherent and Lumentum likewise did not immediately respond.

​

Part of a Broader Crackdown

This Senate bill does not stand alone. It follows months of separate action by the Trump administration's own regulators to squeeze Chinese suppliers out of American digital infrastructure. Earlier this year, the FCC was reported to be drafting a broader rule that would restrict imports of new Chinese optical transceiver models across the wider US market, not just government systems, citing risks of data theft, malware, and service disruption.

That FCC effort has already stirred pushback from the same industry voices, and by mid-September the commission ultimately finalized a narrower rule tightening equipment-authorization requirements rather than an outright import ban, easing some market anxiety, according to the South China Morning Post. The Senate bill introduced Friday takes a more targeted approach: rather than an economy-wide ban, it focuses specifically on the government's own most sensitive systems, a scope that may make it easier to pass even as the wider industry debate continues.

​

What Happens Next

The bill still needs to move through Senate committees and win support in the House of Representatives before it could become law. Given its bipartisan sponsorship, spanning both parties and several politically important states, it may face fewer hurdles than the broader FCC proposal, which has triggered a heavier industry lobbying response.

For now, the legislation is a clear signal that Washington, under both the Trump administration's regulatory agencies and Congress, sees Chinese-made components inside American digital infrastructure as a national security problem that needs addressing, whatever the short-term cost to the AI buildout.
