Description
The Cisco QSFP-H40G-ACU7M is a 40-Gigabit QSFP+ active direct-attach copper (DAC) cable designed for high-performance, short-range connectivity between QSFP ports in data centers and enterprise network environments. With a 7-meter reach, this active copper cable enables reliable 40GBASE-CR4 connections across adjacent racks where passive DAC cables are insufficient.
Engineered for low latency and consistent signal integrity, the QSFP-H40G-ACU7M features integrated active electronics to maintain optimal performance over extended copper distances. It is hot-swappable, energy-efficient, and ideal for high-density switching architectures requiring cost-effective 40G interconnects without the complexity of optical transceivers.
