CPO technology enters adoption phase in data centers requiring advanced packaging ecosystems
Wednesday, February 4, 2026 at 08:22 PM
Co-packaged optics (CPO) technology is entering a growth phase in data centers, integrating electrical-to-optical conversion closer to the processor to reduce power consumption and increase data capacity. The implementation of CPO relies on advanced packaging, heightening the strategic importance of foundries and OSAT providers. While thermal management and maintenance remain challenges, Japanese material and packaging firms are positioned to collaborate with global manufacturers to address these bottlenecks in AI infrastructure.
Context
The adoption of Co-Packaged Optics (CPO) marks a critical shift in AI infrastructure, moving optical engines directly onto the processor package to solve power and latency bottlenecks. TSMC is positioning itself as a central player in this transition, leveraging its COUPE technology to integrate silicon photonics with advanced packaging. This move is expected to drive significant efficiency gains, with industry leaders targeting a 50% reduction in power consumption and a massive increase in data throughput for next-generation data centers.
Commercial scale-up is imminent, with TSMC aiming for mass production of CPO-enabled solutions by 2026. This evolution creates a high-moat ecosystem where advanced packaging expertise is as vital as transistor density. While thermal management remains a challenge, the push for 800G and 1.6T networking speeds makes CPO adoption inevitable for major hyperscalers. Investors should monitor the integration of these capabilities into broader SoIC and CoWoS platforms as the supply chain consolidates around high-end foundry services.
