LevelOne SFP+ Direct Attach Copper Cable 10Gbps Twinax 5m Passive DAC

For high-density 10 Gigabit Ethernet links where optical transceivers would be overkill, this LevelOne SFP+ Direct Attach Copper Cable delivers a ready-to-use, low-latency connection in a single assembly. Unlike separate SFP+ modules and fibre patch cords, the twinax cable has both SFP+ connectors permanently attached, eliminating the cost of two transceivers and the risk of connector contamination. At 5 metres, it bridges top-of-rack switches to servers or storage nodes without the complexity of fibre management, while passive operation keeps power draw below 0.1 W per end.

Highlights

• Direct Attach Copper (DAC) twinax cable with integrated SFP+ connectors on both ends
• Supports 10 Gigabit Ethernet data rates for server, storage, and switch interconnects
• Passive design consumes less than 0.1 W, reducing energy costs and heat in dense racks
• Hot-swappable and MSA compliant for seamless integration with major switch brands
• 24 AWG copper conductors and PVC jacket ensure signal integrity and durability
• Complies with SFF-8431 and SFF-8472, with CE, FCC, and RoHS certifications

In daily use

Installation is as simple as plugging the cable into any SFP+ port—no configuration or separate transceivers required. The 5-metre length is ideal for connecting devices within the same rack or between adjacent racks, and the passive twinax construction provides deterministic latency for latency-sensitive applications such as financial trading or clustered databases. The cable operates reliably in temperatures from 0°C to 70°C and can be stored in harsher conditions from -40°C to 85°C, making it suitable for a wide range of data centre environments. With a bend radius appropriate for standard cable management, it routes neatly alongside power and networking cables.
