Engineering record
Family-level values from the collected technical record. Confirm the selected SKU and required evidence in the quotation.
Technical detail
Review connector, construction, routing and handling details that apply to the selected family and exact SKU.

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.
