Building an AI data center is a bit like assembling a spacecraft. Every component needs to work flawlessly under extreme conditions, and a speck of dust in the wrong place can ruin your whole day. That’s the problem a new industry coalition is trying to solve with expanded beam optical connectors, and 3M just signed on to help.
The manufacturing conglomerate announced on May 12, 2026, that it has joined a multi-source agreement (MSA) group dedicated to creating open, interoperable standards for expanded beam optical (EBO) connectivity. The coalition already includes AMD, Meta, Oracle, Cisco, and Arista Networks, along with more than 16 firms total, all united by the conviction that current connector technology isn’t keeping pace with AI’s insatiable appetite for bandwidth.
What expanded beam optical actually means
Traditional optical connectors work by aligning two tiny glass fibers with near-perfect precision. When dust, vibration, or physical contact disrupts that alignment, performance degrades or fails entirely.
Expanded beam optical connectors take a different approach. Instead of forcing two hair-thin fibers to kiss perfectly, EBO technology widens the light beam at the connection point, then refocuses it on the other side. EBO connectors offer meaningfully better dust and contamination resistance, which reduces the need for frequent cleaning cycles that slow down deployment and maintenance in high-density server environments.
3M framed the technology in ambitious terms, stating that “expanded beam optical technology is increasingly seen as a critical enabler for AI infrastructure.”
Why this coalition matters more than the tech itself
The MSA isn’t just about building a better mousetrap. It’s about ensuring that the mousetrap built by Company A snaps perfectly into the baseplate made by Company B. Without shared specifications, each manufacturer develops proprietary solutions that lock customers into single-vendor ecosystems.
The technical working group is already active and drafting initial specifications for new EBO connectors. The goal is straightforward: create shared blueprints that any participating company can manufacture against, accelerating deployment timelines and driving down costs through competition.
The coalition’s open membership structure also signals that this isn’t meant to be an exclusive club. More participants mean broader adoption, which means the specs become de facto industry standards rather than niche proposals.
What this means for investors
For 3M specifically, this move represents a strategic bet on high-margin components for a sector that shows no signs of slowing down. The company’s materials science expertise in adhesives, films, and precision manufacturing translates naturally to optical connector production.
For the semiconductor and networking names in the coalition, the calculus is different but equally compelling. AMD and Meta need data center interconnects that can keep up with their next-generation chips and AI training clusters. Oracle and Cisco need their networking hardware to remain relevant as optical density increases. Arista, which has built its business on high-performance data center switching, has an obvious interest in making sure the physical layer beneath its products doesn’t become a chokepoint.
One risk: standards bodies move slowly, and AI infrastructure demand moves fast. If the MSA takes too long to finalize specifications, hyperscalers might adopt proprietary solutions out of necessity, rendering the open standard partially irrelevant by the time it arrives. The fact that the working group is already drafting specs suggests the coalition understands this urgency.
