On Friday, Sept 25, 2026, a bipartisan group of US senators introduced the “Securing National Security Systems from Chinese Optical Transceivers Act,” a bill aimed at keeping Chinese-made optical transceivers out of the federal government’s most sensitive national security systems.
The sponsors are Republicans Dave McCormick (PA) and John Cornyn (TX) and Democrats John Fetterman (PA) and Ruben Gallego (AZ). The bill specifically targets China’s Eoptolink and Zhongji Innolight, and it extends an existing federal procurement ban on Chinese semiconductors to optical transceivers. Optical transceivers convert electrical signals to light for fiber-optic transmission; some large AI data centers require millions of them, and Chinese manufacturers dominate the market. In June, the Pentagon added Innolight to its Section 1260H list of alleged Chinese military-linked companies.
The bill grants a five-year transition period to remove existing Chinese units, provides waivers to protect supply and national security, and lets the Commerce and Defense secretaries add more companies to the restricted list later.
Why it matters: The stated security rationale is that advanced transceivers can contain reprogrammable firmware — a potential supply-chain risk — and supporters argue Beijing could exploit that foothold to disrupt US AI and cloud access. But per Reuters, industry is worried the other way: restricting dominant Chinese suppliers could slow the US AI infrastructure buildout as hyperscalers scramble to qualify alternate suppliers. Non-Chinese optical component makers could see a demand tailwind, while data center operators face qualification costs, supply tightness, and potential project delays.
What to watch: Committee markup and whether the five-year transition and waiver provisions survive intact. Listen for commentary from hyperscalers and optical suppliers on qualification timelines and pricing, and watch for any additions to the restricted-company list by the Commerce and Defense secretaries.

Will Washington’s push to de-Chinese the AI supply chain accelerate domestic optical suppliers — or just raise costs and slow the buildout? Share your view in the comments.
