HPE X240 10G SFP+ to SFP+ .65m direct attach copper cable

HPE

HPE JH693A X240 10G SFP+ to SFP+ 0.65m DAC SFP transceiver

SKU CH-WHPD-YZC9M MPN JH693A

A 0.65 metre direct-attach copper cable linking two SFP+ ports at 10 Gbps

  • 10 Gbps direct connection via 0.65 m copper link
  • 25 GB/s throughput for short-range campus links
  • 13 ft length fits tight rack spacing
  • HPE X240 compatibility simplifies SFP+ port pairing
  • New condition ensures factory-tested reliability

Product identity and fit

The HPE JH693A X240 is a 10G SFP+ to SFP+ direct attach copper cable measuring 0.65m in length. It provides a fixed 10 Gbps link between two SFP+ ports on compatible network devices such as switches or servers. This passive twinax assembly is intended for short reach connections inside a rack or between adjacent racks. Buyers needing longer reach or fibre media should consider other media types.

Pre order checks

Verify that both endpoints have SFP+ cages that accept passive direct attach copper cables and that the link speed is negotiated at 10 Gbps. Confirm the 0.65m length matches the physical spacing between the two ports; the cable cannot be extended or cut. Check that the switch or server firmware lists the JH693A as a supported part number to avoid compatibility errors. Ensure no active optical transceiver is required for the intended port configuration.

Sustained load behaviour

The passive copper construction carries the 10 Gbps signal without on board electronics, so power draw remains negligible and latency is minimal. Heat generation is limited to the conductor resistance, allowing continuous line rate traffic without thermal throttling. The fixed 1.25 GB/s throughput is maintained as long as the link remains up and the connected ports operate within specification. No active cooling or firmware management is required during prolonged operation.

Questions about this item

Does the HPE JH693A come with any additional cables or modules, or is the direct attach copper cable the only item included?

The HPE JH693A is a complete direct attach copper cable assembly with SFP+ connectors on both ends. No separate transceivers or patch cables are required for a 10G link.

The product title lists X240 and 0.65m — are there other length or speed variants under the same model number?

JH693A identifies this specific 0.65 metre, 10G SFP+ to SFP+ assembly. Different lengths or speed ratings carry different HPE part numbers.

The spec sheet shows 1.25 GB/s — what actual throughput should I expect when the cable is plugged into two 10G SFP+ ports?

The 1.25 GB/s figure represents the serial lane rate. A 10G Ethernet link over this DAC delivers up to 10 Gb/s of user data throughput.
