The Arista CAB-D-D-400G-1M is a 400Gbps QSFP-DD to QSFP-DD Twinax copper cable with a length of 1 meter. Designed for high-speed, short-range data transmission within racks or between adjacent network equipment, it uses direct attach technology and features robust twinax construction to reduce latency and signal loss.
Compatible with devices requiring the dual-density form factor (QSFP-DD), this DAC supports efficient connectivity in environments utilizing next-generation networking hardware. The passive design eliminates the need for external power sources while ensuring low energy consumption during operation at up to 400 Gbps speeds over its specified distance. It provides reliability via secure connections on both ends using standard-compliant connectors engineered for stable insertion cycles without degradation over time.
