Product Features
Technical Overview
This cable utilizes twinaxial copper construction, which provides excellent signal integrity for high-speed data transmission while maintaining flexibility for easy installation in tight spaces. The 9.8-foot (3-meter) length is ideal for connecting equipment within the same rack or between adjacent racks in data center environments.
The SFP+ connectors feature a latching mechanism that ensures secure physical connection to compatible ports. Both ends are male connectors with identical SFP+ interfaces, creating a symmetrical cable assembly that can be used in either direction without configuration changes.
Key Product Advantages
This direct-attach cable eliminates the need for separate optical transceivers when connecting compatible Cisco devices over short distances, reducing both initial hardware costs and ongoing power consumption. The passive twinax design provides a reliable electrical connection that doesn't require configuration or management overhead.
Cost-Effective Connectivity
By combining the cable and connector functions into a single assembly, this solution reduces the total cost of 10G connectivity compared to using separate transceivers and fiber optic cables for short-reach applications.
- No separate transceivers needed
- Lower power consumption than active solutions
- Reduced component count for simpler inventory management
Simplified Deployment
The plug-and-play design requires no configuration or software setup, allowing network administrators to quickly establish 10G connections between compatible devices.
- Ready to use out of the box
- No driver installation required
- Compatible with standard SFP+ ports
Deployment / Use Cases
This cable is specifically designed for short-reach 10 Gigabit Ethernet connections within data centers, server rooms, and network closets. Its 3-meter length makes it ideal for connecting equipment within the same rack or between adjacent racks where longer fiber runs would be unnecessary and more expensive.
Common deployment scenarios include connecting top-of-rack switches to servers, linking aggregation switches within the same rack, establishing connections between storage arrays and servers, or creating high-speed links between network appliances in compact deployments. The cable works with compatible Cisco SFP+ modules including the SFP-10G-SR and SFP-10G-LR, providing flexibility for various short-reach connectivity requirements.

FAQ
What is the maximum distance this cable supports?
This Cisco twinax cable is designed for short-reach connections up to 3 meters (approximately 9.8 feet). It's ideal for connecting equipment 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 optic cabling.
What types of devices is this cable compatible with?
The SFP-H10GB-CU3M= cable is compatible with network devices featuring SFP+ ports that support direct-attach copper connections. It specifically works with Cisco SFP+ modules including the SFP-10G-SR and SFP-10G-LR. This makes it suitable for connecting Cisco switches, routers, servers, and storage devices that have compatible 10G SFP+ interfaces.
Does this cable require external power or configuration?
No, this is a passive direct-attach cable that requires no external power source or software configuration. The passive design means it operates without active electronics, making it a plug-and-play solution that's ready to use immediately after physical connection. This simplifies deployment and reduces power consumption compared to active cable solutions.
What is the difference between twinax and fiber optic cables?
Twinaxial cables like this Cisco SFP-H10GB-CU3M= use copper conductors for electrical signal transmission, while fiber optic cables use glass or plastic fibers to transmit light signals. Twinax is typically used for shorter distances (up to 7-10 meters for 10G) and is often more cost-effective for these applications. Fiber optic cables can support much longer distances but generally require separate transceivers and have higher overall costs for short-reach connections.
