## Summary description

Compact SFP transceiver OEM X120 JD119B provides 1G optical connectivity using an LC connector on LX single‑mode fiber. Designed for standard SFP ports, it supports 1.25 Gbps line rate and long‑reach links (typical up to 10 km depending on fiber). Suitable for switches, routers and media converters to extend network links between buildings or data center equipment.

## Long description

SFP transceiver module OEM X120 (JD119B equivalent) provides 1.25 Gbps optical link over single‑mode fiber using an LC duplex connector. The module follows the 1000BASE‑LX specification, operates at 1310 nm with a Fabry‑Pérot (FP) laser, and is suitable for long‑reach connections between network devices in standard SFP ports. It is powered from a 3.3 V supply and specified for operation in typical commercial temperature ranges.
Advantages
The SFP Transceiver OEM X120 JD119B delivers gigabit performance in a compact SFP form factor compatible with devices that accept standard SFP modules. Its LC duplex interface and single‑mode LX design enable extended link distances up to the module's rated range. The unit is a direct equivalent to common HP JD119B parts, offering straightforward replacement or expansion of existing 1000BASE‑LX links. Low power operation at 3.3 V and industry‑standard signaling simplify integration into switches, routers and media converters.
Suitable for
Extending network links between buildings or floors over single‑mode fiber
Replacing or expanding 1000BASE‑LX SFP ports in switches and routers
Connecting data center equipment and media converters over distances up to the module's rated range

Manufacturer code / MPN: JD119B\_OEM (equivalent to HP JD119B)
How to use
Insert the SFP module into a compatible SFP port on the switch, router or media converter until it seats and the latch engages. Connect LC duplex single‑mode patch cables to the Tx and Rx ports, ensuring correct orientation. Power on the host device and verify link status via the device LEDs or management interface. Confirm both ends use compatible 1000BASE‑LX single‑mode modules and appropriate fiber type for reliable operation.
Usage recommendations
To achieve the best performance, use single‑mode fiber of appropriate attenuation and quality, keep fiber connectors clean, and verify end‑to‑end compatibility (wavelength, data rate and module type). For distances near the module's limit, check fiber loss and consider using fiber with lower attenuation or an alternative transceiver rated for longer reach.
