Research Institution: Mass Production of 800V DC and CPO Delayed, Optical Module Sector Under Pressure

Odaily Odaily reports that SemiAnalysis, a semiconductor and AI infrastructure research institution, has released its latest research report stating that two key technology roadmaps for AI data centers have faced significant delays. The mass production timelines for both NVIDIA's native 800V DC architecture and CPO (Co-Packaged Optics) technology are behind market expectations.

The report indicates that the shipment timeline for the 800V DC power architecture, which NVIDIA originally planned to adopt on a large scale, has been pushed back to 2028, contrary to earlier market expectations. Meanwhile, CPO shipment volumes in 2027 are expected to be lower than market forecasts, with mass production potentially delayed to 2028-2029, primarily due to factors such as optical engine connection yield rates, ASIC integration challenges, and cost constraints.

SemiAnalysis believes that the 400V DC solution will still begin volume shipments as planned in 2026, and some NPO projects may accelerate. However, the supply chains for power systems, switches, and optical modules that rely on new platforms like Rubin Ultra and Kyber will face delay pressure. The report maintains a relatively positive outlook on companies such as Amphenol, Vertiv, and Legrand, while adopting a more cautious stance on Lumentum, Himax, Navitas, and Wolfspeed.
