Optical Scale Up Fabrics Are Limited By Manufacturing, Not Architecture
Why this matters
Why now

The increasing demand for higher bandwidth and lower latency in AI and high-performance computing is pushing the limits of current fabric interconnects, making optical solutions critical.

Why it’s important

A sophisticated reader should care because optical interconnects are fundamental to scaling future compute infrastructures, impacting the efficiency and cost of AI and data centers.

What changes

The primary constraint for scaling optical fabrics is identified as manufacturing limitations rather than fundamental architectural design, shifting the focus of innovation and investment.
