Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Cisco QSFP-H40G-ACU10M is a 40G QSFP+ Active Copper Cable engineered to deliver high-bandwidth, low-latency connectivity across short to mid-range data center links. Spanning 10 meters, this active copper assembly integrates the cable and transceiver electronics into a single plug-and-play unit, eliminating the need for separate optical modules and fiber infrastructure on shorter runs.Designed for Cisco-certified environments, the QSFP-H40G-ACU10M is hot-swappable and compliant with the QSFP+ MSA standard, ensuring straightforward deployment into compatible Cisco Nexus, Catalyst, and UCS platforms. The active circuitry built into each connector head compensates for signal loss over the copper medium, maintaining clean 40GbE signal integrity at the full 10-meter distance.
This cable is ideal for top-of-rack to end-of-row switch connections, server-to-switch links, and high-density spine-leaf fabric builds where cost-effective 40G connectivity is required. The copper-based design also reduces power consumption compared to optical alternatives on equivalent distances.
Offered in New Open Box condition, this unit has never been installed but may have minimal cosmetic signs of handling on original packaging. All hardware and functionality remain completely intact, making it an excellent value for budget-conscious IT infrastructure deployments. WhaleyComm backs every New Open Box unit with our standard verification process.

Ideal Use Cases
Top-of-Rack Data Center Interconnects
The 10-meter reach makes this cable ideal for connecting top-of-rack switches to end-of-row aggregation switches within the same data center aisle. The active copper design provides reliable 40GbE throughput without the cost overhead of optical solutions on short runs.
Spine-Leaf Fabric Deployments
In modern spine-leaf network architectures, the QSFP-H40G-ACU10M provides a cost-effective way to connect leaf switches to spine switches within close physical proximity. Its plug-and-play design accelerates deployment timelines in high-density build-outs.
Server-to-Switch High-Bandwidth Links
Organizations running bandwidth-intensive workloads such as virtualization, big data, or storage can use this cable to establish direct 40GbE links between servers and ToR switches. The single-assembly format simplifies cable management in dense server environments.

Compatibility Details
Review supported optics, cables, software, management protocols, and environment-specific compatibility guidance.
✓
The Cisco QSFP-H40G-ACU10M is compatible with Cisco platforms supporting QSFP+ 40G ports, including select models in the Cisco Nexus switching family, Cisco Catalyst series switches with 40G uplink modules, and Cisco UCS fabric interconnects. Compatibility with specific line cards and software versions should be confirmed via the Cisco Compatibility Matrix or your WhaleyComm account representative prior to purchase. The cable conforms to the QSFP+ MSA standard, which may allow interoperability with other QSFP+-equipped platforms; however, Cisco TAC support applies only when used within a validated Cisco-to-Cisco deployment.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
New Open Box means the cable has never been installed or used in a production environment, but the original packaging may show minor handling marks. All hardware and functionality are fully intact, and WhaleyComm verifies each unit before shipment.
This cable supports a maximum reach of 10 meters, making it well-suited for intra-rack and short inter-rack connections within a data center environment.
No — the QSFP-H40G-ACU10M is an all-in-one active copper cable assembly with integrated QSFP+ connectors on both ends, so no separate transceivers or optical modules are required.
The cable follows the QSFP+ MSA standard and may function with other QSFP+-equipped hardware; however, Cisco only provides full validation and TAC support for Cisco-to-Cisco deployments. Verify compatibility with your specific platform before ordering.
