Overview

400G QSFP-DD Direct Attach Cable (DAC) series delivers ultra-high-speed connectivity for next-generation data centers and high-performance computing environments. Designed to support 400Gbps data rates with low latency, these passive copper cables provide a cost-effective, plug-and-play solution for short-reach connections between switches, routers, and servers.

Compliant with the QSFP-DD MSA standard, the series ensures seamless compatibility with existing 200G/400G infrastructure and backward compatibility with QSFP28/56 ports. Featuring robust construction and advanced signal integrity, the cables are ideal for high-density deployments in hyperscale cloud networks, AI/ML clusters, and storage systems.

Available in various lengths (1m to 5m), the 400G DACs eliminate the need for external transceivers, reducing power consumption and simplifying cabling management. Their hot-swappable design enables effortless installation, minimizing downtime while maximizing scalability for evolving network demands.
