AI workloads push data center networks to their breaking point. This white paper outlines seven key interconnect validation challenges at 800GE and 1.6T speeds that traditional component-level testing often misses. Learn why bandwidth alone isn’t enough, what causes latency and congestion, and how automated Layer 1-3 emulation helps avoid costly slowdowns. If your interconnects aren’t validated under real AI traffic, your GPUs won’t stay busy.
