OCI-MSA Poised to Become Mainstream Open Standard for AI Scale-Up Optical Interconnects
Understand the story
According to a Semiconductor Engineering report on November 9, 2026, AI scale-up interconnects are moving from copper to optical interconnects, with industry consensus trending toward the OCI-MSA open standard as the mainstream solution. Founding members of the standard include AMD, Broadcom, Meta, Microsoft, Nvidia, and OpenAI. The report analyzes that as AI cluster sizes grow, the limitations of copper interconnects in distance and bandwidth are pushing vendors toward optical interconnects, and OCI-MSA, as an open standard, is expected to gain wide adoption in this transition. This is the only report on this event collected so far, with no follow-up developments or data updates yet.
