Is AI Making Your Organization More Productive or More Dependent?
Key Takeaways
- Azure is the first hyperscaler to deploy 3M’s Expanded Beam Optical technology in its data centers.
- EBO connectors could speed fiber installation while reducing cleaning and maintenance requirements.
- 3M will deploy Microsoft AI across customer service, finance, sales and marketing operations.
Microsoft and 3M announced today a strategic partnership spanning AI data center infrastructure and enterprise transformation. Azure became the first hyperscale cloud provider to deploy 3M's Expanded Beam Optical (EBO) technology, according to the companies.
In return, 3M committed to using Microsoft's AI and digital platforms across customer service, finance, sales and marketing. The arrangement pairs Microsoft's cloud and AI infrastructure with 3M's materials science and precision manufacturing.
"At 3M, we view AI as a powerful tool that can accelerate growth, improve customer experiences and help our teams work more effectively. Our collaboration with Microsoft supports that vision through targeted optimization opportunities for our enterprise while advancing the infrastructure needed to power the future of AI."
- Jon Van Wyck
Executive Vice President & Chief Strategy Officer, 3M
EBO Technology Explained
EBO technology uses an expanded beam optical interface rather than the direct contact found in traditional connectors. Microsoft said early EBO use has shown potential to shorten network deployment timelines and has delivered strong signal performance in live data center conditions.
Traditional optical connectors can require frequent cleaning and inspection due to dust, debris and routine handling that interferes with the point where fiber surfaces meet. By expanding the optical beam before it crosses the connector interface, 3M’s technology makes connections more tolerant of contamination and less dependent on precise physical contact.
For Microsoft, the practical benefit is the ability to install and maintain large numbers of fiber connections more quickly in dense data center environments.
3M is scaling production of the single-mode technology to meet demand from hyperscalers and data center operators. The company also helped establish the EBO Multi-Source Agreement, an industry initiative intended to promote standardization and broader adoption of expanded beam connectivity.
Microsoft-3M Partnership Breakdown
The agreement combines physical data center infrastructure improvements with the deployment of AI across 3M’s business operations.
| Partnership Area | What the Companies Are Doing | Intended Benefit |
|---|---|---|
| Azure optical connectivity | Microsoft will deploy 3M’s EBO fiber-connector technology in Azure data centers | Faster installation, less frequent cleaning and more reliable performance in dense deployment environments |
| EBO manufacturing | 3M is scaling production of its single-mode EBO technology for hyperscalers and data center operators | Support growing demand for the physical infrastructure needed to run cloud and AI workloads |
| Enterprise AI adoption | 3M will apply Microsoft’s AI and digital platforms across customer service, finance, sales and marketing | Simplify processes, improve decision-making, strengthen customer experiences and increase employee productivity |
| Joint technical development | Microsoft and 3M plan continued collaboration between their engineering and commercial teams | Develop additional solutions involving optical connectivity, materials science, manufacturing and Microsoft’s data center and device ecosystem |
How the 3M Deal Fits Microsoft’s AI Strategy
Microsoft's restructured OpenAI partnership, signed in October 2025, remains a centerpiece of its AI strategy. Microsoft holds roughly 27% of OpenAI Group PBC — valued at about $135 billion — with OpenAI committed to purchasing $250 billion in Azure services and Microsoft's IP rights extended through 2032. An independent expert panel now governs any AGI declaration, replacing the previous self-attested clause.
On the infrastructure side, Microsoft's Cobalt 100 ARM-based VMs now span 32 Azure regions, and its Maia 200 accelerator targets faster, more energy-efficient AI inference. That push has helped Azure reach 40% growth and an AI business surpassing a $37 billion annual run rate, up 123% year-over-year, as of fiscal Q3 2026.
Internally, the company faces pressure to convert infrastructure investment into returns. CEO Satya Nadella dismantled the Senior Leadership Team in May 2026, installing a 35-person engineering council and weekly AI ROI reviews following the company's worst stock quarter since 2008.
A July 2026 reduction of about 4,800 roles — following roughly 9,000 cuts in July 2025 — concentrated in Commercial and Xbox.
