2026 OFC Conference Early Insider Analysis: Rubin Driving the 1.6T Optical Communication Supercycle, Who Stands to Gain the Most?

Silicon Photonics and CPO concept stocks are everywhere, who are the real technological winners in the 1.6T era?

————————-

The annual optical communication event, the 2026 OFC Conference, is also set to debut next week. This is a technology exhibition that will determine the flow of funds for future AI computing infrastructure.

With the explosion in demand for AI servers, the optical communication supercycle has begun. This year will mark the first year of 1.6T mass production. Previously, many in the market optimistically expected that power-saving LPO technology would quickly replace traditional modules with DSPs. However, in the ultra-high frequency environment of 1.6T, signal attenuation and equipment interoperability face physical challenges. A few major manufacturers with advantages in DSP chips and laser technology will continue to gain technological dividends and product continuity. Due to stability concerns, the current technical path for LPO technology has gradually shifted to a compromise solution like LRO.

Market funds have recently been heavily chasing Silicon Photonics and CPO concepts, but commercial mass production still faces high hurdles. CPO currently still faces significant heat dissipation challenges and high maintenance costs, and the probability of large-scale adoption in public clouds in the short term is not high. NVDA's next-generation Rubin platform's hardware architecture is the market's weathervane. In pursuit of system stability, for second-tier manufacturers in the market who are over-betting on LPO concepts but lack in-house chip R&D capabilities, this will be a huge potential risk. Once a technological turning point is reached, these popular stocks favored by retail investors often face the risk of downward correction due to news.
