Microsoft Deploys 3M Optical Tech in Azure Data Centers

Microsoft has selected 3M's Expanded Beam Optical (EBO) connector technology for deployment across its Azure data center infrastructure, marking the first announced adoption of the technology by a hyperscale cloud provider. The partnership, announced by both companies, also includes 3M's use of Microsoft AI platforms to modernize its internal business operations.

Why it matters

As AI workloads drive exponential growth in data center capacity requirements, infrastructure bottlenecks in physical connectivity are becoming critical constraints. Optical fiber connections that are faster to deploy and more resilient to contamination can directly accelerate the pace at which cloud providers bring new AI compute capacity online—a competitive advantage measured in weeks or months of revenue and customer acquisition.

Addressing data center deployment speed

Traditional fiber optic connectors require direct physical contact between fiber ends, making them vulnerable to dust contamination and demanding frequent cleaning and inspection during installation. According to the announcement first reported by 3M, the company's EBO technology uses an expanded beam optical interface that eliminates direct contact requirements.

Microsoft's early testing of EBO technology has demonstrated potential to reduce network deployment timelines in certain environments while maintaining strong signal performance under live data center conditions where dust exposure and routine handling are unavoidable. The technology's tolerance for contamination could reduce maintenance overhead as Microsoft scales its infrastructure for generative AI workloads.

Cliff Henson, corporate vice president of Cloud Supply Chain at Microsoft, said the EBO solution is expected to help unlock new levels of performance, reliability and efficiency for cloud and AI workloads.

3M has been scaling production of EBO technology to meet demand from hyperscalers and data center operators. The company helped establish an EBO Multi-Source Agreement to support industry standardization and broader adoption of the technology.

Enterprise AI deployment at 3M

The partnership extends beyond infrastructure. 3M will deploy Microsoft AI and digital capabilities across customer service, finance, sales and marketing functions as part of its enterprise transformation strategy.

One specific implementation involves Microsoft Frontier Company engineers working with 3M's Global Business Services team to automate customer order management. The companies are developing an AI agent-driven workflow to handle credit checks, delinquency assessments and system updates with human oversight controls and a custom monitoring dashboard for real-time visibility.

This solution is expected to reduce manual effort, improve process speed and consistency, and accelerate cash flow while freeing staff for higher-value work.

Jon Van Wyck, executive vice president and chief strategy officer at 3M, described AI as a tool to accelerate growth and improve customer experiences while supporting the infrastructure needed to power AI's future.

Both companies indicated they intend to continue technical collaboration between engineering and commercial teams, with focus areas including reliability, deployment speed, density and long-term scalability across Microsoft's data center and device ecosystem.

Details of the partnership were announced by 3M and Microsoft in a joint statement.
