SFP Transceiver Module HPE X120

The HPE X120 SFP Transceiver Module HPE X120 (MPN: JD119B, EAN: 885631249611) is a compact optical network transceiver designed for Gigabit Ethernet links. It provides a maximum data transfer rate of 1000 Mbit/s via a standard SFP interface and uses an LC fiber optic connector for single-mode or multimode fiber connections depending on system configuration. With compact dimensions (55 mm × 15 mm × 12 mm) and a weight of approximately 0.02 kg, this HP Enterprise module is compatible with a range of HP networking equipment, including HP 6600 and 8800 series switches.

Advantages

The module supports a standardized SFP form factor for easy hot-swappable installation and straightforward compatibility with equipment using SFP ports. Its LC connector allows reliable fiber connections with established cabling systems. The transceiver's small size and low weight minimize rack space and make it suitable for dense port deployments. Being manufactured for HP Enterprise, it aligns with vendor compatibility lists for selected HP switches and reduces the need for third-party adapters.

Suitable for

• Establishing Gigabit Ethernet fiber links between switches and routers
• Replacing or upgrading SFP ports in HP 6600 and 8800 series equipment
• High-density installations requiring compact SFP transceivers
• Data center uplinks and enterprise access layer connections

How to use

Ensure the switch or router supports the HPE X120 SFP transceiver (check the device compatibility list). Power down the device or follow the vendor's hot-swap procedure if supported. Align the module with the SFP cage and gently insert it until it clicks into place. Connect the LC fiber cable to the transceiver, observing correct polarity for duplex links. Configure the switch port for the appropriate speed and duplex settings if required; many modern devices will auto-negotiate Gigabit settings. Monitor link LEDs and system software to confirm the port is active and functioning.

Recommendations

Use quality LC fiber cables and maintain clean connector end-faces to ensure optimal signal integrity. Verify firmware and compatibility lists for your HP 6600 or 8800 series device before deployment. For long-haul or specific fiber types, confirm the transceiver's supported fiber mode (single-mode or multimode) with the equipment documentation.
