At the 2026 OFC Global Optical Communications Conference, an industry analyst used a vivid metaphor to describe the current state of the industry: "Today's AI data centers are like rush-hour traffic in a city—without expressways, everything grinds to a halt. Optical communications is precisely the expressway system designed for this scenario." The reason this analogy resonates so powerfully is that it captures a profound shift that is already underway: optical interconnects are no longer just a supporting component of data centers; they have become a core variable that directly defines the upper limit of AI computing power.
The speed of change is breathtaking. Just a year ago, 800G optical modules were the "next-generation technology" dominating industry discussions. Today, they have already become the mainstream specification for backbone interconnects in AI data centers. According to forecasts from industry research institutions, global demand for 800G products is expected to reach 45 to 50 million units in 2026, while the true growth engine has already shifted to 1.6T, with full-year demand projected to exceed 25 million units. LightCounting's predictions further indicate that the optical module market will maintain rapid growth of around 60% in 2026, with the global market size approaching USD 60 billion by 2031.
But speed never comes without a cost. As optical module transmission rates march from 400G to 800G and then sprint toward 1.6T, power consumption is becoming an unavoidable challenge for data center operators. An 800G optical module consumes approximately 25 to 30 watts, while the power draw of a 1.6T DR8 version has already surpassed 45 watts. This means that in a large-scale data center deploying tens of thousands of optical modules, the energy consumed by optical interconnects alone could reach the megawatt level—not even accounting for the additional cooling overhead required for heat dissipation.
It is against this backdrop that low-power technology routes have become the most closely watched theme in the 2026 optical module industry. LPO solutions, by eliminating the DSP chip, can achieve approximately a 50% reduction in power consumption in certain short-reach application scenarios. Silicon photonics technology has already captured 72% market share in 1.6T optical modules, becoming the mainstream industry choice thanks to its combined advantages of low power and low cost. Looking further ahead, CPO technology is expected to see large-scale deployment in 2027, holding the potential to fundamentally reshape the architectural paradigm of optical interconnects.
For North American data center procurement decision-makers, this is both the best of times and the most complex of times. On the one hand, the pace of technology iteration is unprecedented, with the generational transition window from 800G to 1.6T potentially spanning only two to three years. On the other hand, the parallel evolution of multiple technology routes—from traditional pluggables to LPO, LRO, XPO, NPO, and on to CPO—greatly compounds the complexity of procurement decisions. A misstep in selection not only exposes one to the sunk costs of substantial investment but also risks missing critical first-mover advantages as competitors accelerate their own deployments.
HaloWill's product strategy is designed precisely around this core tension. We adhere to a "full-route, full-speed" product portfolio philosophy. Rather than placing a concentrated bet on a single technology route in our R&D, we provide customers with the optimal solution tailored to different application scenarios. On the 800G product line, HaloWill offers both traditional DSP-based solutions and LPO solutions, enabling customers to choose flexibly based on their network's transmission distance, power consumption requirements, and budget constraints. In the 1.6T domain, our silicon photonics integration solution has completed engineering validation and possesses the technology reserves to smoothly evolve toward 3.2T, allowing customers' network infrastructure investments to span multiple product generations. In high-density, short-reach scenarios, HaloWill's active optical cables and silicon photonics short-reach interconnect solutions can significantly reduce power consumption per unit of bandwidth and total cost of ownership while decreasing cabling complexity within racks.
Particularly noteworthy is that HaloWill's product design has embedded the concept of "generational compatibility" from the very beginning. Our 800G and 1.6T modules adopt unified packaging interfaces and management protocols, enabling customers to migrate from 800G to 1.6T without the need for large-scale replacement of switch ports or redesign of rack cabling schemes. In a reality where data center deployment cycles routinely span months and deployment costs are substantial, this seamless upgrade capability translates into tangible and meaningful return on investment.
We have also observed that leading North American cloud computing companies are upgrading optical modules from "generic procurement items" to "strategic partnership assets." Giants such as NVIDIA and Google have already begun locking in the supply of critical components and modules through long-term agreements and are even deeply involved in their suppliers' technology roadmap planning. HaloWill consistently approaches North American customers with an open and collaborative spirit, establishing deep cooperative relationships and providing full transparency and flexibility in technology route selection, product customization, and delivery timelines.
Ultimately, selecting an optical module is no longer merely about evaluating a specifications sheet. It demands that procurement decision-makers possess forward-looking judgment on technology trends, a clear-eyed awareness of supply chain risks, and a deep-seated trust in their partners' long-term capabilities. Through solid product strength, stable and reliable supply assurance, and a forward-looking layout aligned with future technology trajectories, HaloWill aspires to become the most trusted optical interconnect partner for North American data center customers and channel partners in the era of AI computing power.
We sincerely invite you to contact the HaloWill North America business team to obtain our latest product roadmap and sample testing opportunities, and to explore together the optimal optical interconnect solutions for the next generation of AI data centers.
