Microsoft and 3M are expanding their partnership with a focus on AI data centre infrastructure and enterprise AI. Under the agreement, Microsoft will become the first announced hyperscale cloud provider to deploy 3M's Expanded Beam Optical (EBO) technology across its Azure Cloud and AI Infrastructure. The data centre element centres on 3M's proprietary EBO technology, which uses an expanded beam optical interface to make fibre connections quicker to install, more tolerant of contamination, and easier to maintain. The technology can reduce the need for routine cleaning and inspection while maintaining optical performance. 3M reports that early deployments have demonstrated the potential to shorten network installation timelines while maintaining reliable signal performance. To support wider deployment, 3M is increasing production capacity and helped establish the Expanded Beam Optical Multi-Source Agreement. Alongside infrastructure collaboration, 3M will adopt Microsoft's AI and digital platforms to support its own enterprise transformation.
