This year’s Optical Fiber Conference (OFC) took place in Los Angeles. It felt less like a conference and more like an urgent industry call to action. Nearly 18,000 attendees from around the world, a packed exhibition floor, and a clear message: optical infrastructure is now a first-order challenge in the AI era.

The event remains the premier global gathering for optical communications, combining deep technical content with a highly commercial exhibition. This year, however, the center of gravity was unmistakably AI data centers, and the optical backbone required to scale them. Its speed and scale exceed OFC’s traditional telecom orientation by at least an order of magnitude.

From a logistics standpoint, the Los Angeles Convention Center delivered: well-organized, efficient, and large enough to host the ecosystem. That said, the split between the two main halls turned navigation into a workout. As one attendee put it: “Are they in two different counties or what?” Not entirely wrong.

What stood out most was the energy. It was palpable. The industry showed up in force: vendors, hyperscalers, startups, and investors, creating the sense of a market that is hyper-accelerating, not just evolving.

Key Themes and Announcements
The narrative across plenary sessions, show-floor demos, and side conversations converged around a few core themes:

• AI is driving everything
  Optical networking is no longer background infrastructure. It is becoming the limiting factor for scaling AI clusters.
• Bandwidth and power are now inseparable problems
  The shift to 224G lanes, the push toward 448G, and the unprecedented production ramp rate of 1.6T optical modules highlight how aggressively the roadmap is being pulled forward.

• Optics is moving closer to compute
  Co-packaged optics (CPO), near-package optics, and optical I/O are transitioning from research topics to strategic priorities. These solutions, in many cases, are proprietary – meaning that the commodity nature of pluggable optical modules is fundamentally changing.

On the commercial side, announcements reflected a market preparing for deployment, not experimentation. Companies like Coherent and Lumentum showcased competing approaches to integrating optics closer to ASICs, while Corning emphasized fiber and connectivity solutions designed for AI-scale data center density.

Interoperability also took center stage, with organizations like the Ethernet Alliance demonstrating multi-vendor readiness from 800G to 1.6T: an essential step toward real deployment.

Silicon Photonics: Hot… But For How Long?
Silicon photonics was everywhere: on booths, in presentations, and in investor discussions. The technology is clearly moving from promise to necessity, driven by the limits of electrical I/O.

At the same time, the narrative is evolving. The question is no longer whether silicon photonics works – it does. The question is where the value accrues.

Increasingly, bottlenecks are shifting toward:

• packaging and integration
• power and thermal management
• fiber-to-chip connectivity
• manufacturing and testing at scale

This is where the opportunity lies. For startups, the play is not to rebuild the stack, but to own a critical piece of the food chain. For strategics and investors, this creates a rich landscape for targeted M&A and selective bets.

There was no shortage of startups at OFC; many were highly credible, technically differentiated, and clearly positioned for partnership, acquisition, or growth capital. For large corporate and financial investors, the event effectively functioned as a live deal-sourcing platform.

Is silicon photonics a long-term hot sector? The demand driver – AI infrastructure – is real and durable. But timelines, architectures, and winners remain uncertain. As always, when a theme becomes consensus, selectivity becomes critical.

Final Takeaways
OFC 2026 confirmed a structural shift: optics is moving from a supporting role to a strategic layer in the AI infrastructure stack.

A few conclusions stand out:

• The roadmap is compressing – innovation cycles are accelerating under AI demand, and the volumes are huge
• Integration is the new battleground – value is migrating toward packaging and system-level solutions
• Interoperability matters more than ever – deployment readiness is becoming a differentiator
• The ecosystem is investable – strong startup activity with clear M&A relevance

Finally, beyond the data points, the conference conveyed something harder to quantify: conviction. This is an industry moving with urgency and alignment.

There is so much happening in such a hot segment that we will be publishing a dedicated market report on silicon photonics shortly.
