The insatiable "computing hunger" of Artificial Intelligence is creating an unprecedented "highlight moment" for the global optical communication industry.

AI has fundamentally altered all market forecasts in the optical communications field, Bandwidth demand within data centers is exploding, and high-speed optical transceivers have emerged as the primary beneficiary.

In 2024, deployments of 400G and higher-speed optical transceivers grew by 250% year-on-year, with projections indicating sustained high growth of over 50% in 2025. More notably, shipments of 800G optical transceivers are expected to achieve a year-on-year increase of 100% in 2025. Meanwhile, 1.6T products are beginning to enter the market, and 3.2T technology is under accelerated development.

01 Market Pulse: The Transformation Revealed by Data

As the "nervous system" for data flow within data centers, the accelerating upgrade cycle of optical transceivers directly mirrors the expansion of AI computing demand. In 2024, approximately 22.5 million optical transceivers were deployed globally, a figure projected to reach 34.5 million units in 2025.

The market size for high-speed optical transceivers is expected to reach $14 billion in 2025, growing to approximately $24 billion by 2029. The regional demand landscape is also shifting. While North America currently leads, accounting for 38% of global revenue driven by cloud giants like Google, Meta, Microsoft, and Amazon, demand from China and the Asia-Pacific region is equally robust, fueled by local investments in computing infrastructure and AI applications.

02 Technology Drivers: How AI is Reshaping the Supply Chain

Training large AI models requires interconnecting tens of thousands to millions of GPUs, making traditional network architectures a critical bottleneck. A technical expert from a leading manufacturer stated, "AI demands optical transceivers with significantly higher data rates and lower latency."

Co-packaged Optics (CPO) is a key pathway to address this challenge. CPO, which integrates the optical engine and switch chip on a common substrate, can improve power efficiency by 3.5 times, enhance reliability by 10 times, and reduce operational provisioning times to 77% compared to traditional designs. Compared to pluggable transceivers, CPO can reduce power consumption by 50% and increase bandwidth density by a factor of 3.

Linear-drive Pluggable Optics (LPO) has also gained attention as an intermediate solution. By removing the DSP chip, LPO aims to lower power consumption and latency. One manufacturer has launched an 800G LPO solution that has passed certification by an international tech giant, reportedly reducing power consumption by 30%.

03 Future Trends: From 800G to 1.6T and Beyond

The roadmap for speed upgrades is clear. 800G is becoming the mainstream standard for 2025-2026, replacing 400G as the preferred choice for data center network upgrades. 1.6T technology is on the horizon, with major switch chip vendors actively promoting the next port speed upgrade.

The industrialization timeline for CPO is taking shape. Industry forecasts suggest that 2025-2026 will be a critical period for validation and initial production, with mass production scaling up from 2027-2028 and widespread adoption expected post-2029. This evolution signifies a deeper integration of optics and electronics, moving from discrete components to a unified system.

The synergy between optical networks and AI is creating a cycle of mutual empowerment. Optical networks provide the high-speed, low-latency connectivity foundation for AI, while AI technologies are, in turn, enabling optical networks to evolve from "passive transmission" to an "actively intelligent" new phase. The revolution in optical communications, driven by AI, is just beginning.
