Power Consumption: The Next Core Challenge Facing AI Data Centers
As the demand for AI large-model training and inference grows exponentially, data center power consumption is escalating from a back-end engineering concern into a core strategic issue that directly impacts operational economics. A large-scale AI training cluster often requires tens of thousands or even hundreds of thousands of high-speed optical interconnect ports. At such massive scale, even a small difference in per-module power consumption is dramatically magnified, directly affecting the data center’s PUE and total cost of ownership.
Multiple industry experts have pointed out that the evolution toward low-power, high-integration optical module technology has become an irreversible core trend. In the North American market, hyperscale cloud service providers have already incorporated optical module power efficiency into their core procurement evaluation criteria, giving it a priority on par with speed and price. Technology paths that can significantly reduce per-bit power consumption are receiving increasingly higher procurement priority.
It is against this backdrop that LPO and silicon photonics integration have emerged as the two most-watched innovation focal points in the 2026 optical communications industry.
LPO: Breaking the Power Bottleneck of High-Speed Optical Modules
LPO technology achieves power consumption reductions of up to 50% by eliminating the power-hungry DSP chip found in traditional optical modules and using a linear-drive architecture to directly perform signal equalization and retiming. This breakthrough in energy efficiency makes LPO an ideal solution for short-reach interconnect scenarios within AI data centers.
In 2026, LPO technology is accelerating from the lab to volume commercial deployment. Leading North American cloud service providers have already incorporated 800G LPO into their 2026 mass deployment plans, and LPO solutions from multiple suppliers have secured key customer qualifications and orders. Market research indicates that LPO module revenue share is expected to capture a significant portion of the optical module market, becoming a key growth engine for the industry.
LPO's value extends beyond direct power savings. By removing the DSP chip, the material cost of the optical module is significantly reduced and the physical architecture becomes simpler, helping to improve reliability in large-scale deployments. In a typical 10,000-GPU AI training cluster, the total economic benefit of an LPO solution can exceed that of traditional solutions by several percentage points. For North American distributors, this means being able to offer customers a differentiated product portfolio that combines performance, cost, and energy efficiency advantages.
Of course, the large-scale commercialization of LPO still faces challenges related to standard unification, multi-vendor chip interoperability, and the maturity of operational management systems. This is precisely why selecting a supplier with deep technical accumulation and fully validated products is critically important.
Silicon Photonics Integration: A Scalable Technology Path for the Next Generation
If LPO addresses the question of “how to reduce power consumption,” then silicon photonics integration answers the question of “how to achieve higher speeds in a scalable way.”
As traditional EML laser-based optical module solutions move toward 1.6T and higher bandwidths, they face mounting pressure from chip supply constraints and continuously rising costs. Silicon photonics, with its CMOS-compatible manufacturing process and high integration advantages, is widely regarded by the industry as the inevitable technology direction for high-speed optical modules. Silicon photonics is expected to capture a 60% market share in the 1.6T era.
The core advantage of silicon photonics integration lies in replacing multiple discrete EML lasers with an external CW laser source, dramatically simplifying the internal architecture of the optical module. This not only reduces bill-of-materials costs but also mitigates the supply risk associated with multiple discrete chips. Within the CPO (Co-Packaged Optics) technology evolution path, silicon photonics is similarly a core enabling technology. CPO tightly packages the optical engine together with the ASIC chip, significantly breaking through the power and bandwidth density bottlenecks of electrical interconnects and representing a definitive direction for addressing future, even higher compute demands. CPO is expected to see initial deployment starting from 800G/1.6T port scenarios, entering the early deployment phase between 2026 and 2027.
