Application and routing

In a 128-node AI cluster, the hybrid interconnection solution (single-mode optical modules + DAC) saves over 20% in deployment costs and ~21.6% in total power consumption vs. an multi-mode optical modules solution. It eases cooling pressure of switches, cuts data center power costs, and DAC’s near-zero power optimizes PUE—building green, sustainable computing infrastructure while meeting interconnection needs.
