10-GbE SFP+ Direct Attach Cable

The HPE J9281B is a 3.3 ft copper cable with SFP+ connectors permanently fixed to each end. It provides a low-cost 10-Gigabit link between compatible network ports without separate transceivers. The 100 ohm impedance and 1.31 nsec/ft delay suit short rack or cabinet runs. It is built for commercial network environments using ProCurve or standards-based SFP+ equipment.

Replaces separate transceivers and patch cords

This cable removes the need to buy two SFP+ modules and a fibre or copper patch lead. The jump is worth it when the link distance stays within 3.3 ft and the hardware accepts passive direct-attach cables. It is not for links that exceed the fixed length or for gear that requires active or optical modules.

Plug both ends into matching SFP+ ports

Installation is a simple push-in action on each end; no tools or software configuration are required. The main issue is inserting the connector upside down or into a port that does not support passive copper direct-attach. Verify port compatibility before deployment to avoid a link that will not come up.

Questions about this item

What SFP+ port spacing does the 3.3 ft cable require?

The cable uses SFP+ connectors on both ends, so it fits any standard SFP+ port pair without special spacing requirements.

Which orientation do the SFP+ connectors need during insertion?

Each SFP+ connector has a latch tab that must face down; push until the latch clicks to avoid a loose link.

When should the cable be replaced in a 10 GbE link?

Replace it if the 100 ohm impedance is compromised by kinks, the 2 % crosstalk limit is exceeded, or the 1.31 nsec/ft delay budget is no longer met.
