Description
The Cisco QSFP-H40G-ACU10M is a 10-meter active copper direct-attach cable engineered for reliable 40-Gigabit Ethernet connectivity between QSFP ports. Designed for short-reach, high-performance data center environments, this cable provides a cost-effective alternative to optical solutions while maintaining excellent signal integrity over extended copper distances.
Built to support 40GBASE-CR4 applications, the QSFP-H40G-ACU10M enables seamless connections between switches, routers, and network appliances within racks or across adjacent racks. Its active design allows for longer reach than passive copper cables, making it ideal for deployments requiring consistent throughput, low latency, and reduced power overhead.
Cisco-tested and validated, this cable ensures dependable interoperability with Cisco platforms, simplifying installation and reducing operational complexity in enterprise and service provider networks.
