  • 25 Gbit/s throughput for high-speed networking
  • SFP28 connectors on both ends for direct device links
  • 28 ft copper cable keeps rack runs tidy
  • Direct-attach design removes separate transceivers

Direct Attach Copper Cable

This HPE cable provides a 25 Gbit/s link between two SFP28 ports. It uses a copper assembly rated for direct-attach connections. The cable measures 3.28 ft in length. It is supplied new under part number R4G19A.

Suited for short rack links; not for fibre runs

The copper construction suits adjacent switches or servers inside one rack. Buyers needing longer reach or optical isolation must choose a different cable type. No fibre optics are present despite the supplier listing.

SFP28-to-SFP28 25 Gbit/s interface

The single deciding specification is the paired SFP28 connectors operating at 25 Gbit/s. Both ends must accept this exact module format. Verify port compatibility before purchase.

Questions about this item

How can I verify the 25 Gbit/s link is active after connecting the SFP28 ends?

Check the switch or NIC port LEDs for a solid link light and confirm the interface reports 25 Gbit/s speed in the OS or management console.

What comes in the box with the R4G19A and what must be purchased separately?

The cable assembly with SFP28 connectors on both ends is included; compatible SFP28 ports on switches or NICs are required separately.

Which version of the 3.28 ft 25 Gbit/s direct attach cable should I choose for my HPE switch?

The R4G19A is the single 1 metre copper variant; select it when your HPE hardware lists this part number for 25 Gbit/s SFP28 links.
