3M’s fiber optic breakthrough is helping power AI’s massive buildout

Inside a modern data center, speed is everything. As artificial intelligence continues to reshape industries, the pressure on technology companies to build and activate massive computing infrastructure fast has never been greater. One of the biggest bottlenecks? Getting large numbers of fiber optic links installed quickly and reliably. Using traditional fiber connections can be a labor-intensive process that is sensitive to contamination. 3M is addressing that challenge with its Expanded Beam Optical (EBO) technology, a fiber-optic interconnect solution designed to simplify connectivity.

The problem with traditional fiber optic connections

Fiber optic cables transmit data light through extremely small optical pathways. Traditional physical-contact connectors require highly precise alignment at the point of contact, often with carefully polished surfaces to maintain signal performance. A single speck of dust can interrupt the connection and require inspection, cleaning or rework.

That level of precision requires specially trained technicians, careful handling and frequent rework, all of which translate into time and cost. For hyperscalers and data center operators racing to bring AI infrastructure online, that can become a significant operational challenge.

A solution that transforms optical connections

3M’s EBO proprietary ferrules use a lens array to expand the optical beam at the connection interface. By spreading the beam wider at the point of contact, it avoids the same kind of direct physical fiber-to-fiber contact used in traditional connectors and eliminates the need for precision polishing and reduces inspection and cleaning. The result is a connector that is more forgiving, more durable and dramatically faster to deploy.

3M debuted its EBO concept in 2019 and the team engineered the technology around three priorities: high-density connectivity for demanding computing environments, manufacturability at scale, and a differentiated, expanded-beam…
