Cisco SFP-H10GB-CU2M
10GBASE-CU SFP+ Cable 2 Meter, Original Cisco
Product Highlights
When you need reliable, low-latency 10 Gigabit Ethernet connectivity between devices in the same rack or adjacent racks, running fiber with separate transceivers at both ends adds unnecessary cost and complexity. The Cisco SFP-H10GB-CU2M eliminates that overhead entirely.
This original Cisco 10GBASE-CU SFP+ passive direct attach copper (DAC) twinax cable delivers 10GbE performance over a fixed 2-meter length with SFP+ connectors pre-terminated on both ends. Its passive design requires no active electronics — just plug it in and go. That translates to ultra-low latency, minimal power draw, and zero configuration for point-to-point links between switches, servers, and storage.
Built with 30AWG copper twinax and a Cisco-coded EEPROM, the SFP-H10GB-CU2M is recognized natively by a wide range of Cisco platforms including Catalyst, Nexus, ASR, MDS, and UCS series equipment. Whether you're building out a top-of-rack data center topology, connecting server NICs to access-layer switches, or linking storage arrays in a SAN, this cable delivers the density, simplicity, and performance that 10G environments demand — at a fraction of the cost of optical alternatives.
Features & Benefits
Passive Direct Attach Copper Design
The SFP-H10GB-CU2M uses a fully passive twinax copper design with no active electronic components between the two SFP+ ends. This eliminates the need for separate transceiver modules, reduces power consumption to as low as 0.1W, and delivers near-zero latency — critical advantages in dense data center environments where every watt and microsecond counts.
Cisco-Coded EEPROM for Plug-and-Play
Each cable includes a Cisco quality identification (ID) coded EEPROM, enabling native recognition on Cisco platforms without compatibility warnings or manual overrides. Simply insert the SFP+ connector into any supported port and the link comes up automatically — no CLI commands or license keys required.
Broad Cisco Platform Compatibility
Supported across a wide range of Cisco infrastructure including Catalyst 2960-S/X/XR, 3560-X, 3750-X, 3850, 4500/4500-X, and 6500 series switches; Nexus 2000, 3000, 4000, 9000, and 9500 series; ASR 901, 903, 1000, and 9000 series routers; MDS 9000 storage switches; and UCS fabric interconnects. This breadth of support makes it a versatile stocking item for any Cisco-centric environment.
Hot-Swappable & High-Density Friendly
The SFP+ form factor is the industry's smallest 10G interface, maximizing port density per chassis. Cables are fully hot-swappable — you can add, remove, or replace them without powering down the host device, minimizing maintenance windows and reducing risk during network changes.
Deployment Scenarios
Data Center Top-of-Rack Connectivity
Connect servers to top-of-rack (ToR) switches at 10GbE speeds within the same cabinet. The 2-meter passive DAC cable is perfectly sized for standard 42U racks and delivers the lowest possible latency for east-west traffic between compute and network tiers.
Switch-to-Switch Stacking & Uplinks
Use the SFP-H10GB-CU2M for short-reach 10G uplinks between access-layer and distribution-layer switches in campus or branch deployments. Its passive design keeps power budgets low while providing full 10 Gbps throughput for aggregation links.
Storage Area Network (SAN) Interconnects
Link storage arrays, SAN switches (such as MDS 9000 series), and host bus adapters over 10G with minimal latency. The DAC cable's copper construction provides a reliable, low-cost alternative to fiber for short-reach storage fabric connections.
UCS Fabric Interconnect Links
Connect Cisco UCS blade chassis or rack servers to UCS fabric interconnects using 10G SFP+ DAC cables. The Cisco-coded EEPROM ensures seamless integration within the UCS management domain without compatibility issues.
