10 GbE SFP+ Direct Attach Cable

This 9.84 ft twinaxial cable connects two SFP+ ports for 10 GbE links. It is a passive copper assembly rated at 10 Gbps with 30 AWG conductors and 100-ohm impedance. The black jacketed cable suits rack-to-rack or switch-to-server runs where fiber modules are not required. It targets network engineers who need a low-power, cost-effective interconnect for compatible HP and HPE equipment.

Plug-and-play with latching SFP+ ends

Each end carries an SFP+ latching plug that clicks into standard SFP+ cages without tools. The passive design draws no external power and follows SFF-8431 and SFF-8432 mechanical specifications. Installation fails when ports are keyed for active optical modules only, when the switch enforces vendor lock-out, or when the cable length exceeds the port's supported reach for passive copper.

Check port compatibility and reach limits

Verify that both endpoints accept passive SFP+ direct attach cables and do not require active or optical transceivers. Confirm the hardware vendor allows third-party twinax cables; some platforms block non-OEM modules. Ensure the 9.84 ft length fits within the maximum passive copper distance supported by your specific switch or NIC model.

Questions about this item

How can I confirm the SFP+ cable is operating at 10 Gbps after connecting it to my switch?

Verify the link status LEDs on both SFP+ ports show an active 10 GbE connection and run a throughput test between the linked devices to confirm 10 Gbps performance.

What is included with the J9283BST cable and do I need separate transceivers?

The box contains one 9.84 ft twinaxial DAC with latched SFP+ connectors on both ends; no separate transceiver modules are required because the connectors are built into the cable.

Which version of this direct attach cable should I choose for an HP Firepower 1040 switch?

Select the J9283BST model; it is 100 % HP compatible and equivalent to the HP J9283B cable specified for the Firepower 1040.
