40G QSFP+ direct-attach cable

The HPE JH234A is a 40G QSFP+ to QSFP+ direct-attach copper cable measuring 3.28 ft. It provides a fixed, low-latency link between two QSFP+ ports without separate transceivers. The assembly is factory-terminated and tested for 40 Gbps operation. It arrives new and ready for immediate installation.

Suitable for short rack connections

This cable suits builders linking switches, servers or storage arrays within a single rack or adjacent racks where the 3.28 ft reach is sufficient. It does not suit deployments that require longer runs, fibre media or breakout configurations to multiple lower-speed ports.

Passive 40G QSFP+ copper construction

The single deciding specification is the passive 40G QSFP+ copper construction, which limits reach to 3.28 ft and requires QSFP+ ports that support direct-attach cables. Verify port compatibility before purchase.

Questions about this item

Which devices need QSFP+ ports to connect with this 3.28 ft DAC cable?

Both ends use QSFP+ connectors, so each linked device — switch, router, server NIC or storage controller — must provide a matching QSFP+ cage.

Will the 3.28 ft length reach between adjacent rack units when I keep my older 1 U switches?

At 3.28 ft the cable spans roughly one rack unit vertically, so it typically connects ports on neighbouring 1 U appliances without strain.

How do I confirm the 40G link is up after plugging in the JH234A?

Check the port LEDs on both sides for a steady link light and verify the interface shows 40 Gb/s speed and no errors in the OS or switch CLI.
