A critical technology for next-generation AI data centers, co-packaged optics (CPO), is facing significant delays, with meaningful mass production now unlikely until after 2026 due to persistent manufacturing yield issues.
According to supply chain sources cited in a Digitimes report, the timeline for CPO to replace traditional pluggable optical modules is far longer than the market anticipates. "To enable scale deployment in AI data centers, the production yield must be high enough for CPO to be more cost-effective than existing solutions," the report states, identifying the yield problem as the "biggest obstacle" for the entire supply chain.
The delay comes despite intense pressure from cloud AI infrastructure providers to enhance performance and reduce costs. While the demand for CPO is clear and growing, the supply side is struggling to climb the maturity curve. The difficulty in manufacturing and validation means that even by 2026, actual production volumes will be "extremely limited."
This setback could slow the pace of cost-per-FLOP improvements in AI hardware, potentially benefiting incumbent optical module makers like Lumentum (LITE) and Coherent (COHR) in the short term. For chip designers heavily invested in the technology, the delay complicates future product roadmaps and cost structures.
Nvidia Pushes, Rivals Watch
Among the key players, Nvidia (NVDA) is the most aggressive in driving the CPO transition. The AI giant has been pressuring its supply chain partners to be ready for mass production starting in 2025, highlighting the performance benefits of CPO to its customers.
In contrast, Broadcom (AVGO) and Marvell Technology (MRVL), which have also invested heavily in CPO, are taking a more conservative approach to their rollouts. Broadcom has reportedly begun initial, small-scale shipments to customers. However, sources indicate neither company is pushing for mass adoption as forcefully as Nvidia.
Ultimately, the entire semiconductor ecosystem stands to benefit from a successful CPO transition, which promises to break through performance and cost ceilings. However, the industry's growth is now capped not by demand, but by the fundamental ability of the supply side to produce the technology at a high enough yield and scale.
