Cisco SFP-H10GB-CU1M
10GBASE-CU SFP+ Cable 1 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 optic cabling is often overkill — adding unnecessary cost, complexity, and power draw. The Cisco SFP-H10GB-CU1M solves this with a simple, passive direct attach copper (DAC) twinax cable that delivers full 10GbE performance over a 1-meter reach.
This original Cisco SFP+ cable features integrated SFP+ connectors on each end and a passive 30AWG twinax copper assembly, eliminating the need for separate transceivers and fiber patch cords. With power consumption of just 0.1W, it dramatically reduces per-port energy costs compared to optical SFP+ modules — a meaningful advantage at scale in power-conscious data center environments.
The SFP-H10GB-CU1M is hot-swappable and factory-encoded with Cisco-compatible EEPROM data, enabling true plug-and-play deployment across a wide range of Cisco platforms including Catalyst, Nexus, ASR, and UCS series equipment. Whether you're building out a new top-of-rack switching layer, connecting servers to access switches, or establishing short-reach inter-switch links, this DAC cable delivers the performance of 10GbE at a fraction of the cost of optical connectivity.
Features & Benefits
Passive Direct Attach Copper
The SFP-H10GB-CU1M uses a passive twinax copper design with no active electronic components. This means ultra-low power consumption (0.1W) and near-zero latency compared to optical alternatives. For short-reach links inside the rack, passive DAC cables are the most energy-efficient and cost-effective interconnect option available.
Hot-Swappable & Plug-and-Play
Each end of the cable features an integrated SFP+ connector that is fully hot-swappable — install or replace without powering down the host switch, router, or server. The factory-programmed Cisco EEPROM ensures instant recognition on supported Cisco platforms, eliminating manual configuration and reducing deployment time.
Broad Cisco Platform Compatibility
This cable is supported across a wide range of Cisco platforms including Catalyst 2960-X/XR, Catalyst 3650, Catalyst 3850, Catalyst 4500-X, Catalyst 6500/6800, Nexus 5000/7000/9000, ASR 901/903/920/1000/9000 series, and UCS Fabric Interconnects. Always verify compatibility for your specific platform and IOS/NX-OS version using the Cisco Transceiver Module Group (TMG) Compatibility Matrix.
MSA-Compliant Design
Built to comply with SFF-8431 and SFF-8472 Multi-Source Agreement (MSA) standards, the SFP-H10GB-CU1M ensures interoperability with 10GBASE XENPAK, X2, and XFP interfaces on the same link. This standards-based approach protects your investment and simplifies multi-vendor environments.
Deployment Scenarios
Top-of-Rack Switch-to-Server Connectivity
Connect servers directly to top-of-rack (ToR) access switches using a low-cost, low-latency 10GbE DAC link. The 1-meter length is ideal for servers and switches co-located in the same cabinet, eliminating the cost of separate SFP+ optics and fiber patch cords.
Intra-Rack Switch-to-Switch Links
Establish high-speed 10GbE inter-switch links (ISLs) between stacked or adjacent switches within the same rack. The passive design keeps power consumption minimal while delivering full line-rate 10 Gigabit throughput for east-west traffic.
Data Center & Enterprise Wiring Closet
Deploy in enterprise wiring closets or small data center pods where short-reach 10GbE uplinks are needed between distribution and access layer switches. The SFP-H10GB-CU1M provides a cost-effective alternative to optical modules for distances under 1 meter.
