Product Features
Technical Overview
This 10GBASE-CU cable operates as a passive twinaxial copper assembly, supporting 10 Gbps data rates with minimal latency. The SFF-8431 SFP+ connectors interface directly with SFP+ ports, eliminating the need for separate transceivers. The cable length of 2 meters (6.6 ft) is optimized for rack-to-rack or within-rack connections in data center environments.
The twinaxial construction provides balanced signal transmission with inherent noise rejection, suitable for electrically noisy environments. As a passive cable, it draws no power from host devices and requires no configuration, making it a straightforward connectivity solution.
Key Product Advantages
This cable delivers reliable 10 Gigabit connectivity with several practical benefits for network administrators. Its plug-and-play installation reduces deployment time compared to fiber solutions, while the passive design ensures long-term reliability with no active components to fail.
Cost-Effective 10G Connectivity
Eliminates the need for separate optical transceivers, reducing per-port costs for short-distance 10 Gigabit links.
- No transceiver purchases required
- Lower total cost of ownership
- Simplified inventory management
Simplified Deployment
Ready to use out of the box with no configuration or power requirements, saving installation time.
- Plug-and-play operation
- No software configuration
- Immediate connectivity
Reliable Performance
Passive twinaxial construction ensures consistent signal quality with minimal latency for time-sensitive applications.
- Stable data transmission
- Low bit error rate
- Consistent throughput
Deployment / Use Cases
This cable is ideal for connecting SFP+ ports within the same rack or between adjacent racks in data center environments. Common applications include linking top-of-rack switches to servers, connecting aggregation switches, or establishing inter-switch links in high-performance computing clusters.
The 2-meter length suits most within-rack scenarios while providing enough slack for proper cable management. Organizations can deploy these cables for storage area network connections, virtualization host connectivity, or as backbone links in enterprise network cores where 10 Gigabit throughput is required.
Data Center Server Connections
Connect servers with SFP+ network interfaces to top-of-rack switches for high-speed data access.
Switch-to-Switch Linking
Establish 10 Gigabit trunk connections between Catalyst switches in stack or distributed configurations.

FAQ
What is the maximum distance this cable supports for 10 Gigabit Ethernet?
This Cisco 10GBASE-CU cable is designed for a maximum reach of 2 meters (6.6 feet). It is optimized for short-distance connections within the same rack or between adjacent racks in data center environments. For longer distances, you would need to consider active optical cables or separate transceivers with fiber cabling.
Does this cable require external power or configuration?
No, this is a passive twinaxial cable that requires no external power or configuration. The SFF-8431 SFP+ connectors interface directly with compatible SFP+ ports, providing plug-and-play connectivity. There are no active components to configure, and the cable draws no power from the host devices.
Which Cisco devices are compatible with this SFP+ cable?
This cable is compatible with numerous Cisco Catalyst switches including the 2960, 2960G, and 2960S series models, as well as the Cisco UCS 6140XP Fabric Interconnect. It works with any device featuring SFP+ ports that support 10GBASE-CU direct-attach copper connectivity.
What is the difference between passive and active direct-attach cables?
Passive cables like this Cisco SFP-H10GB-CU2M= contain only copper conductors with no signal conditioning electronics, making them simpler and more reliable. Active cables include signal amplification or retiming electronics to support longer distances but require power from the host device. Passive cables are typically more cost-effective for short reaches up to 3-5 meters.
