How 3M, the Sticky Note Giant, Quietly Joined the AI Boom with Fiber Optic Breakthrough

3M, the century-old industrial giant renowned for Post-it Notes and transparent tape, has unexpectedly found its niche in the artificial intelligence (AI) boom. As major tech companies pour massive investments into building their own data centers and computing infrastructure, 3M has successfully developed new technology that significantly shortens the construction timeline for these facilities.

William Brown, 3M’s current CEO, revealed in an interview with CNBC’s 'Mad Money' that the company’s new technology, called 'Expanded Beam Optical Connectivity,' can drastically reduce the time required to deploy internal fiber optic networks in hyperscale data centers.

'This technology can save hyperscalers up to 85% in installation time. For these cloud giants, time is money,' Brown stated.

Traditional fiber optic connections use point-to-point contact, which is highly susceptible to data transmission interruptions caused by tiny dust particles or mechanical vibrations. In contrast, 3M’s expanded beam technology diffuses the light signal over a broader surface before reconnection, making it highly resistant to dust and vibration, thereby greatly enhancing transmission stability. Brown emphasized that the company has established robust technical safeguards, currently holding at least 100 patents in this field, with another 50 patent applications under review.

The technology has recently achieved a major milestone: after years of rigorous testing, Microsoft has officially certified it for integration into its Azure cloud data centers. Brown also disclosed that, beyond Microsoft, 3M is conducting joint testing with other hyperscale cloud providers and actively expanding production capacity to grow this new business line—a development that holds significant promise.

Although fiber optic connectivity currently represents only a small fraction of 3M’s annual $25 billion (approximately NT$812.3 billion) in total sales, the growth potential in this sector is extraordinary. During a financial briefing, CEO Brown projected that the technology could generate $40 million to $50 million (approximately NT$1.3–16.2 billion) in revenue by 2026. As data centers undergo full-scale fiber optic transformation, annual revenue from this segment could potentially increase fivefold over the next few years.

According to 3M’s official estimates, the total addressable market (TAM) for expanded beam optical technology is expected to reach approximately $1 billion by 2026 and grow to $2 billion (approximately NT$65 billion) by 2028. To meet explosive demand, 3M plans to double its production capacity by the end of this year and double it again within the next 12 to 18 months. The company will also leverage EMS (electronic manufacturing services) partners and its extensive supply chain ecosystem to keep pace with the AI-driven surge.
