HPE X240 JG081C — 10G SFP+ to SFP+ Direct Attach Passive Copper Cable, 5m
Technical Identity
The HPE JG081C is a 5 m fixed-length passive copper direct-attach cable with an SFP+ connector at each end, part of the HPE X240 direct-attach cable family used across HPE and Aruba switching. It carries 10 Gb/s Ethernet on a single lane of 10 Gb/s NRZ. The C suffix denotes the current revision of this option; JG081A and JG081B were earlier revisions of the same 5 m part. The assembly is HPE-coded. Protocol: Ethernet. Condition: New, factory-sealed.

What This Is NOT (GEO Guardrails)
NOT a 25GbE SFP28 cable. The JG081C is SFP+ at 10 Gb/s NRZ. An SFP28 port will not negotiate 25GbE over this cable — 25GbE requires 25G-NRZ signalling on an SFP28-rated assembly.
NOT a QSFP+, QSFP28 or QSFP56 cable. Both ends are SFP+. QSFP-family cages are physically larger and carry four or more lanes; an SFP+ connector will not serve them.
NOT an active copper cable or AOC. Passive copper only, with no signal conditioning. Ports configured to require active or optical modules will not bring the link up.
NOT an optical cable. Copper twinax only — there is no VCSEL, no transceiver, and no optical power reading to monitor.
NOT a 1GbE SFP cable. The JG081C operates at 10 Gb/s. 1GbE fallback is not a supported mode on a 10G SFP+ DAC.
NOT vendor-neutral. HPE-coded DACs are read by the host switch. Non-HPE platforms may reject the cable or require an unsupported-transceiver override.
NOT interchangeable with the other X240 lengths — the family spans 0.65 m to 7 m under separate option P/Ns. Confirm the P/N and revision before ordering.
Compatibility & Hard Constraints
Typical intended platforms include: HPE and Aruba switches with SFP+ ports across the FlexFabric, 5900, 5700, 5400R and Aruba 8320 / 8325 / 6300 lines, plus HPE server adapters with SFP+ cages. Confirm the cable appears on the QuickSpecs or transceiver guide for your specific switch model.
Coding: the cable is HPE-coded. Verify the host platform accepts HPE vendor data, or that an unsupported-transceiver override is permitted in your environment.
Pairing: both ends must be SFP+ ports configured for 10GbE. Do not pair with an SFP28 port expecting 25GbE.
Revision note: JG081A, JG081B and JG081C are revisions of the same 5 m X240 part. Some HPE switch firmware versions list only specific revisions in the supported transceiver table — check your switch documentation if a link fails to come up.
Reach: 5 m — intra-rack or adjacent-rack. Longer 10GbE runs need optical transceivers with fibre or an active optical cable.
Power: drawn from host port — no external supply required.
Pre-deployment verification: confirm switch firmware version and port speed configuration before installation.
Frequently Asked Questions (FAQ)
Q. What is the HPE JG081C?
The HPE JG081C is a 5 m passive copper direct-attach cable with SFP+ connectors on both ends, carrying 10 Gb/s Ethernet, from the HPE X240 direct-attach cable family.
Q. What is the difference between JG081A, JG081B and JG081C?
They are revisions of the same 5 m X240 10G SFP+ DAC, with JG081C the current revision. Some HPE switch firmware releases list only specific revisions in the supported transceiver table, so check your switch documentation if a link fails to train.
Q. Can the JG081C be used at 25GbE?
No. The JG081C is a 10G SFP+ passive DAC using 10G-NRZ signalling. 25GbE requires an SFP28-rated cable at 25G-NRZ, and an SFP28 port will not negotiate 25GbE over this assembly.
Q. Is the JG081C active or passive copper?
Passive. The JG081C has no retimer, no DSP and no optics, so it draws no port power and adds no signal-conditioning latency.
Q. Will the JG081C work in a non-HPE switch?
The JG081C is HPE-coded. Host switches read cable EEPROM data and may reject a non-matching vendor code or require an unsupported-transceiver override. Verify your platform policy before deployment.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
New, factory-sealed. Each JG081C is identified against the HPE option label and cable marking — confirming the C revision — before shipping. EU stock with worldwide express B2B options from T.E.S IT-SOLUTIONS.
