Cisco QSFP-H40G-ACU10M= 40GBASE-CR4 Active Copper | 10 m QSFP+ — QSFP-H40G-ACU10M=

Keep short-reach 40 GbE links simple with Cisco QSFP-H40G-ACU10M=. This 10 m 40GBASE-CR4 active copper cable is designed for QSFP+ environments where adjacent racks, top-of-rack switches, and nearby servers need direct connectivity. It delivers a practical alternative to optical modules when the link distance is within copper range and the priority is efficient deployment. Active copper is often the right choice for dense infrastructure because it reduces component count and keeps installation straightforward. That matters in data centers where speed of deployment, port utilization, and predictable short-run connectivity all affect operating cost. For teams standardizing on Cisco networking hardware, this cable aligns with the platform and avoids the extra parts associated with transceiver-based designs. Use it where 40 GbE throughput is needed over a short span and where a factory-direct Cisco cable is the cleaner procurement decision. It is a focused solution for high-density environments that value direct attach simplicity and reliable rack-level connectivity.
