The figures
Tom's Hardware reports that Microsoft is building 35 data centers in the US.reported The company plans for 134 additional facilities. Chinese companies currently supply 66% of the global market for optical transceivers.reported Only two US-based firms, Coherent and Lumentum, produce these modules for data centers.

Behind the figures
The market share figure reflects the global distribution of optical transceiver production. The count of US manufacturers was determined by identifying domestic producers capable of supplying the specific modules required by modern data centers. The data center counts represent Microsoft's current construction and planned expansion.
What it means for your stack
Optical transceivers convert electrical signals to light for fiber optic transmission. Data centers use them to connect AI GPUs and server racks. These modules offer faster speeds, lower latency, and less power consumption than copper connections. A ban would remove the majority of available supply.
Building on this
Developers relying on high-throughput AI infrastructure face potential deployment delays. The ITI stated that AI chips could sit unutilized without these transceivers. With only two domestic suppliers, scaling up to replace Chinese imports may not be possible immediately. This limits the ability to expand GPU clusters rapidly.
Why it matters
- Supply chain constraints could delay the deployment of new AI models requiring massive compute resources.
- Engineers may need to design systems that account for potential hardware shortages or longer lead times.
- The reliance on a small number of US vendors increases the risk of bottlenecks in network infrastructure.
- Policy decisions on hardware imports directly impact the speed and scale of AI data center construction.

For readers
Developers
- Potential hardware shortages could delay the deployment of large-scale AI applications.
- Network architecture may need to account for limited availability of optical interconnects.
Policy
- Regulators are balancing security concerns against supply chain stability for AI infrastructure.
- Lobbying efforts highlight the tension between national security and technological advancement.
Investors
- Supply constraints could impact the growth trajectory of AI-dependent companies.
- Domestic manufacturers may see increased demand if imports are restricted.
