Splitter cable for QSFP+ to SFP+

The HPE JG329A X240 is a 3.28 ft direct-attach copper cable that splits one QSFP+ port into four SFP+ connections. It is built for network administrators who need to break out a 40 GbE uplink into four 10 GbE links inside a rack. The cable arrives new and ready for immediate installation.

Suits breakout cabling in dense racks

This splitter suits engineers deploying 10 GbE servers or switches that connect to a 40 GbE aggregation layer. It is not for links that require fiber reach beyond the rack, nor for ports that use QSFP28 or SFP28 form factors. Buyers needing longer runs or different media should select an alternative cable type.

3.28 ft fixed length

The 3.28 ft length is set at manufacture and cannot be changed. Measure the exact distance between the QSFP+ panel and each SFP+ device before ordering, because excess slack or a short reach will both require a replacement cable.

Questions about this item

What QSFP+ port speed must my switch or NIC support for this HPE JG329A splitter cable to operate?

The cable splits one QSFP+ port into four 10G SFP+ links, so the QSFP+ side must run at 40 Gb/s aggregate.

Can I plug legacy 1 Gb SFP modules into the four SFP+ ends of this JG329A cable?

The SFP+ connectors are wired for 10 Gb/s lanes; 1 Gb SFP modules are not electrically compatible with this direct-attach assembly.

After connecting the HPE X240 cable, how do I verify each 10G link is up on my switch?

Check the switch port status for four active 10 Gb/s SFP+ interfaces and confirm link lights on all four SFP+ connectors.
