Direct-attach link for 10 Gbps racks

The HPE J9281D is a passive twin-axial cable with SFP+ male connectors on both ends, delivering a 10 Gbps TCP/IP link up to 3.28 ft. It suits network engineers who need a fixed, low-latency connection between adjacent switches or servers.

Passive construction removes power draw

Because the assembly is passive, it requires no external power and adds no heat to the rack, simplifying cable management in dense 1U or blade chassis. The direct-attach design also eliminates separate transceiver modules and patch cords.

SFP+ ends lock into standard cages

Each end inserts into a standard SFP+ cage and latches securely, so the link stays intact during routine chassis vibration or cable-tray routing. The 3.28 ft length fits typical intra-rack runs but will not reach between separate cabinets.

Questions about this item

Will the passive twin-axial cable degrade and need replacement after extended use?

The passive twin-axial construction has no active electronics to wear out, so the cable itself does not require scheduled replacement under normal handling.

What limits the link distance to 3.28 ft at 10 Gbps?

The 3.28 ft length is the maximum reach for this passive SFP+ direct-attach cable at 10 Gbps; longer runs need active or optical modules.

Does the passive SFP+ cable generate noticeable heat or draw extra power during all-day operation?

As a passive assembly it draws negligible power and produces no measurable heat beyond the connected ports themselves.
