SFP-H10GB-ACU10M= Cisco 10GbE LAN DAC (Twinax) 1000cm Cable

High-Density 10GbE SFP+ Direct-Attach Copper Twinax Interconnect with the SFP-H10GB-ACU10M=

SFP-H10GB-ACU10M= is a Cisco passive SFP+ direct-attach copper (DAC) twinax cable engineered for predictable 10GbE server-to-switch links inside the rack, where latency, determinism, and operational simplicity are prioritized over long-reach optics. By using a fixed 1-lane SFP+ to SFP+ electrical path, SFP-H10GB-ACU10M= supports stable link behavior in dense top-of-rack designs and reduces the variables associated with optical transceivers.

In modern compute platforms—whether CPU-only virtualization clusters, NVMe-rich storage nodes, or GPU-enabled inference hosts—consistent 10GbE connectivity is foundational for east-west traffic and management networks. SFP-H10GB-ACU10M= complements PCIe-based NICs and switch uplinks by delivering a low-power, low-complexity interconnect that keeps thermal budgets under control and preserves front-to-back airflow. The 10m passive copper architecture is optimized for in-rack patching, enabling clean cable management across adjacent racks or extended rows without introducing optical cleaning and inspection procedures.

Why Choose the SFP-H10GB-ACU10M=?

SFP-H10GB-ACU10M= provides an enterprise-ready approach to 10GbE density by consolidating transceiver and cable into a single, validated assembly, supporting repeatable deployments and straightforward sparing. For operations teams, SFP-H10GB-ACU10M= simplifies provisioning, accelerates moves/adds/changes, and delivers a pragmatic scalability profile for expanding top-of-rack port counts while maintaining consistent link characteristics.

Cisco designs cabling solutions to align with data centre standards for reliability and lifecycle control, focusing on interoperability within Cisco switching ecosystems, controlled tolerances, and predictable field performance across high-density racks.
