Serenity: Mizuho Research confirms that both the CPO and 800V DC deployment have incurred no delays, and the recent sell-off in the related sectors was purely collateral damage.

BlockBeats News, June 17, Serenity reposts the latest research report from Mizuho Securities and comments that the recent concentrated sell-off of CPO concept stocks is entirely a foolish misjudgment of the market.

The Mizuho research report points out that concerns about mass production delays of co-packaged optics (CPO) and lagging deployment of 800V DC are unfounded, as both technical routes are progressing as scheduled, with the mass production window expected to remain between 2028 and 2029. Driven by Nvidia's CPO switch (3.2T Spectrum-X) demand for volume production in 2027, Mizuho also raised its shipment forecasts for optical engines (OE).

On the technical route, Mizuho believes that InP DFB lasers remain the long-term mainstream direction for CPO, naming $SIVE as a related beneficiary; VCSEL and microLEDs are still unproven in short-distance rack and inter-chip scenarios above 1.6T, and are unlikely to become mainstream replacements in the short term. Regarding 800V DC deployment in data centers, incremental shipments are expected to start in 2027, with further penetration in 2028.

Nvidia's senior vice president of the networking division also publicly denied that Spectrum-X Ethernet CPO switches are delayed, confirming that mass production and customer deliveries will proceed as scheduled in the second half of 2026.
