TL;DR
The US is drafting a measure to ban new Chinese optical transceivers used in data centers, aiming to protect infrastructure from security threats. The measure remains in proposal, not yet implemented, with significant implications for supply chains and industry dynamics.
The US Federal Communications Commission is currently drafting a measure to restrict the import of new Chinese optical transceivers used in data center networks, according to Reuters. This proposed regulation aims to enhance national security by preventing potential data theft, malware, and service disruptions linked to Chinese hardware. The measure is still in the draft stage and has not been enacted, but its potential impact on global supply chains and industry players is significant.
On August 4, Reuters reported that the FCC is preparing a draft regulation to ban the import of new Chinese optical transceivers, devices critical for high-speed data transmission within data centers. The measure is intended to safeguard US infrastructure from security threats associated with Chinese equipment, particularly amid ongoing geopolitical tensions.
The draft is not final; sources emphasize it remains under review and could be modified or abandoned before any official implementation. The move is part of broader US efforts to control Chinese technology, but it targets the network interconnect layer rather than the chips themselves.
Chinese vendor Zhongji Innolight, which holds a significant share of the global transceiver market, especially outside China, faces potential restrictions. The company, which derives about 90% of its revenue outside China and over 60% from the US market, was added to the Pentagon’s list of Chinese military-linked companies in June, signaling increased scrutiny.
However, the measure would not affect the vast existing stock of Chinese transceivers already installed in US data centers. Industry experts highlight that most hardware purchased through 2025 remains operational, meaning the immediate security threat from current hardware persists regardless of future import restrictions.
Implications for Data Security and Industry Supply Chains
This proposed measure indicates a strategic shift in US policy, emphasizing control over the hardware infrastructure that connects data centers rather than the chips used in computation. While it aims to mitigate security risks, it also signals efforts to reshape industry supply chains by favoring domestic or allied suppliers. The move underscores the increasing importance of the network interconnect layer in national security and technological competitiveness, with potential ripple effects across global markets.

US-China Tech Rivalry and Regulatory Approaches
Over the past year, US authorities have targeted Chinese technology through various regulatory mechanisms, including export controls on chips and restrictions on equipment like drones and routers. The current draft represents a continuation of these efforts, focusing on the network infrastructure that underpins data flow. Unlike export controls on advanced chips, which restrict sales abroad, this draft targets the importation of Chinese hardware into the US, aiming to prevent potential security breaches at the network level.
Chinese vendors dominate the global transceiver market, with approximately 70% of shipments. Their hardware has been widely adopted in US data centers due to cost and availability. The potential ban on new imports raises questions about future supply and the security of existing hardware already deployed.
Officials have emphasized security concerns, but critics argue the existing hardware already in place presents a more immediate risk, and that the proposed restrictions may primarily serve industrial policy goals, such as reshoring manufacturing capacity to US firms.
“The real story is that the existing Chinese transceivers already in US data centers are unaffected by any import ban, meaning the security concern is more about future hardware than current exposure.”

Unconfirmed Status of the Proposed Regulation
The draft regulation remains in the proposal stage, with no final decision made. It is uncertain whether the FCC will approve, modify, or shelve the measure before any formal enactment. Additionally, the scope and specifics of the restrictions could change significantly, and there is no clear timeline for finalization.
Next Steps in Regulatory and Industry Response
The FCC is expected to continue consultations and potentially publish the draft for public comment later this year. Industry stakeholders are likely to lobby and prepare for possible adjustments. If finalized, the regulation could take effect within the next year, prompting shifts in supply chain sourcing and strategic planning among US data center operators and vendors.
Key Questions
Will the existing Chinese transceivers in US data centers be affected?
No, the proposed regulation targets only new imports; existing hardware already installed remains unaffected in the immediate term.
How does this measure differ from US chip export controls?
It targets the importation and authorization of Chinese hardware, specifically transceivers, rather than restricting the export of US chips and technology to China.
What are the security concerns driving this regulation?
Officials cite risks of data theft, malware, and service disruption from Chinese-made hardware inside US critical infrastructure.
Could this measure impact global supply chains?
Yes, given Chinese vendors’ dominant role in transceiver shipments, restrictions could lead to supply shortages or increased costs for US and global data centers.
When might the regulation be finalized?
The timeline remains uncertain; the FCC could publish a final rule within the next year, but this is not guaranteed.
