Product Features
Technical Overview
This direct attach cable utilizes twinaxial copper construction with 100-ohm impedance to support 10 Gigabit Ethernet connections. The passive design requires no external power, drawing minimal power from the host device while maintaining signal quality across the full 7-meter length.
The cable terminates in two SFP+ network male connectors that comply with MSA (Multi-Source Agreement) standards, ensuring interoperability with a wide range of networking equipment. The 24 AWG wire gauge provides optimal signal transmission with reduced crosstalk and electromagnetic interference.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

Deployment / Use Cases
This 10GbE SFP+ DAC is ideal for connecting switches within racks, linking servers to top-of-rack switches, or establishing short-distance connections between networking equipment in data centers. The 7-meter length provides flexibility for cable management while maintaining signal integrity.
Common deployment scenarios include connecting HPE switches in enterprise networks, establishing server-to-switch links in virtualization environments, and creating backbone connections between networking equipment. The cable supports both copper and fiber switch ports that accept SFP+ modules, making it versatile for mixed infrastructure environments.
Data Center Interconnects
Connect switches within the same rack or adjacent racks without the cost and complexity of fiber optic transceivers and separate fiber cables.
Server Connectivity
Link servers with 10GbE network interfaces to switches for high-speed data transfer in virtualization, storage, and high-performance computing environments.
Physical Profile
The cable features a black PVC jacket that provides durability and flexibility for routing through cable management systems. With an approximate weight of 14.20 ounces (402.56 grams), the cable is lightweight yet robust enough for permanent installations. The SFP+ connectors feature a secure latching mechanism that ensures reliable connections in vibration-prone environments.

FAQ
What switches is this SFP+ DAC cable compatible with?
This cable is 100% compatible with HPE J9285B switches including 5400zl, 1040, 2930F, and 5406 models. It has also been tested for compatibility with Cisco routers and switches, and works with MSA-compliant equipment from Ubiquiti, D-Link, Netgear, Supermicro, TP-Link, and other manufacturers that accept uncoded SFP+ modules.
What is the maximum length for this direct attach cable?
This direct attach cable has a fixed length of 7 meters (approximately 23 feet). The passive twinax copper design maintains 10 Gbps data transfer rates across this entire distance without signal degradation, making it suitable for connections within racks or between adjacent equipment in data center environments.
Does this cable require external power or active components?
No, this is a passive direct attach cable that requires no external power source or active components. The twinax copper design draws minimal power from the host device while maintaining signal integrity across the 7-meter length. This passive approach increases reliability by eliminating potential points of failure found in active cables.
Can I hot-swap this cable without shutting down my equipment?
Yes, this cable features hot-swappable SFP+ connectors that allow you to install or remove the cable without powering down your networking equipment. This enables maintenance and reconfiguration during normal operations, minimizing downtime in production environments.
