Direct-attach 40G QSFP+ link

This HPE JH235A cable provides a direct-attach copper link between two QSFP+ ports at 40 Gb/s. The 9.84 ft length suits rack-to-rack or intra-rack connections in data-centre environments. It arrives new and ready for immediate deployment.

Best for fixed QSFP+ ports, not for optical runs

The passive DAC design fits switches, servers or storage appliances with native QSFP+ cages that support copper direct-attach. Buyers needing longer reach, fibre media or breakout configurations should look at optical transceivers and patch cables instead.

9.84 ft passive copper reach

The 9.84 ft (3 m) length is the decisive specification; it sets the maximum separation between the two QSFP+ endpoints without adding active circuitry or fibre. Verify that your rack layout and port spacing fall within this distance before ordering.

Questions about this item

What does the 40G rating mean when the cable is installed between two switches?

The 40G rating indicates the cable supports 40 Gigabit per second throughput when both ends are connected to compatible QSFP+ ports.

What does the QSFP+ interface cap in practice?

QSFP+ connectors on this cable limit the link to 40 Gbps and a 3 metre reach, so longer runs need optical modules instead.

How much rack space does the 9.84 ft length need for routing?

At 9.84 ft the cable spans about three metres, so plan slack for that distance between the two QSFP+ ports in your rack.
