Description
The Cisco QSFP-H40G-ACU7M is a 40G QSFP active direct-attach copper (DAC) cable designed for high-performance, short-reach connectivity between QSFP ports in data centers and enterprise networks. With a 7-meter active copper design, this cable extends reach beyond passive DAC limits while maintaining low latency, power efficiency, and reliable signal integrity.
Built for 40GBASE-CR4 applications, the QSFP-H40G-ACU7M enables cost-effective interconnects between switches, routers, and network appliances within racks or across adjacent racks. Its factory-terminated QSFP connectors allow for quick, plug-and-play deployment without the need for optical transceivers, reducing overall infrastructure cost and complexity.
Ideal for dense networking environments, this Cisco active DAC cable delivers dependable 40-gigabit performance while supporting efficient airflow and simplified cable management.
