JD118AHPE H3C JD118A Compatible 1G SFP Transceiver Module
Built for hosts recognizing JD118A, this HT-manufactured SFP module delivers 1G transmission at 850nm. Its rated reach is 550m on 50 / 125µm OM2 MMF 275m on 62.5 / 125µm OM1 MMF 220m on 62.5 / 125µm FDDI MMF, with Duplex LC as the physical interface. The specifications and engineering guidance below support structured fiber installations preserve a documented and serviceable optical channel, while keeping HT manufacture separate from the OEM cross-reference.

Applications and Optical Link Design
Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The Duplex LC interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.
Before deployment, check the host port type, supported data rate and firmware requirements. The 1G interface configuration must match the remote equipment; sharing a SFP housing alone does not make two transceiver types interoperable.
The multimode channel should use the fiber grade associated with the stated 550m on 50 / 125µm OM2 MMF 275m on 62.5 / 125µm OM1 MMF 220m on 62.5 / 125µm FDDI MMF reach. Keep the Duplex LC end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.
HPE H3C Compatibility and Factory Testing
The module is checked for host recognition as JD118A, link establishment and diagnostic reporting. Physical cage fit alone is not treated as evidence of compatibility. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Optical Acceptance, Diagnostics and Handling
For this model, the specified transmit-power range is -9.5~-3dBm; receiver sensitivity is < -17dBm. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. Diagnostic monitoring is listed as Supported. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.
Structured Fiber Pathways and Serviceability
Treat the transceiver as part of the complete channel. Follow the intended patch-panel route, maintain bend control and leave service access around the port. Confirm connector polish and fiber type at every mated pair; a documented service allowance is preferable to excess slack concealed inside a rack. For this model, the principal parameters are data rate 1.25Gbps, wavelength 850nm, rated reach 550m on 50 / 125µm OM2 MMF 275m on 62.5 / 125µm OM1 MMF 220m on 62.5 / 125µm FDDI MMF.
Ordering Information
When ordering, specify JD118A, JD118A, quantity and intended host platform. Project labels can repeat these details for receiving and asset records. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
Quality Assurance and Packaging
Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. Customer references, rack groups and project packing lists can be added for volume orders.
Frequently Asked Questions
Is this an original HPE H3C transceiver?
No. It is an HT-manufactured compatible alternative for equipment that specifies JD118A, not an original HPE H3C-branded module.
Which fiber and connector are required?
Use Duplex LC with MMF. The specified maximum reach is 550m on 50 / 125µm OM2 MMF 275m on 62.5 / 125µm OM1 MMF 220m on 62.5 / 125µm FDDI MMF, subject to fiber quality and total link loss.
Can it be mixed with another wavelength or reach version?
Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
