The JD490A-C is an HP-compatible 100BASE-FX Small Form-Factor Pluggable (SFP) transceiver that delivers 100 Mbps fiber optic links up to 2 km over multimode fiber. It features hot-swappable deployment, digital diagnostics monitoring (DDM), 1310 nm wavelength, and an SC connector interface.
The JD490A-C is compatible with a wide range of HP switches and routers that feature SFP slots, including the Aruba 2530, 2540, 2920, 2930F, 5400R, 8200, as well as the HP FlexNetwork and ProCurve series.
Yes. The JD490A-C is designed to interoperate with third-party devices that support 100BASE-FX SFP modules, provided they accept industry-standard SFF-8472 diagnostics and SC-type connectors.
This transceiver supports 50/125 µm and 62.5/125 µm multimode fiber (MMF) with an SC duplex connector. It is not compatible with single-mode fiber.
The JD490A-C operates at a 1310 nm wavelength and supports link lengths up to 2 km over multimode fiber.
The module supports a fixed data rate of 100 Mbps in full-duplex mode, compliant with IEEE 802.3u 100BASE-FX standards.
Yes. The JD490A-C is hot-swappable, allowing insertion or removal without powering down the host device, minimizing network downtime.
Yes. It provides real-time diagnostics for optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage via the I²C interface.
Operating temperature ranges from 0 °C to 70 °C (32 °F to 158 °F), with storage temperature from –40 °C to 85 °C (–40 °F to 185 °F) and relative humidity of 5 % to 95 % non-condensing.
Power off the device or disable the port, remove the dust cap, align the transceiver with the SFP slot, slide it in until it clicks, then power on or re-enable the port. Configure the interface for 100BASE-FX in the device’s CLI or GUI.
No additional drivers are required. The transceiver is fully managed by the host device’s built-in SFP interface and IEEE 802.3u protocol support.
The module complies with IEEE 802.3u, SFF-8472, RoHS, CE, FCC, and UL safety standards, ensuring interoperability and regulatory compliance.
The JD490A-C includes a one-year limited warranty and access to technical support via phone or web ticket. Extended warranty and on-site support plans are available.
Verify fiber cleanliness, check SC connector seating, confirm matching fiber types and wavelengths on both ends, review DDM diagnostics for power levels, and ensure correct port configuration.
Use high-quality multimode fiber, keep connectors clean, maintain bend radius ≥10 mm, monitor DDM metrics regularly, and ensure proper cable management to minimize attenuation.
The JD490A-C supports OM1 and OM2 multimode fiber. While it can operate over OM3/OM4, you must verify that the switch or router enforces 100BASE-FX link settings to avoid mode conditioning issues.
