1 Gbps SFP transceiver for single-mode fibre

This HPE Aruba J4859D module converts an SFP port to a 1000Base-LX LC single-mode link. It delivers 1 Gbps transfer rate over distances up to 10 km. The unit is compatible with OfficeConnect 1820 and multiple Aruba switch series.

Network links that need 10 km reach

It suits administrators extending campus or building-to-building connections where single-mode fibre is already installed. Buyers needing copper RJ-45 connectivity or shorter multimode runs should look at other transceiver types.

LC single-mode interface with 10 km range

The LC single-mode connector and 1000Base-LX wavelength determine whether this module matches the fibre plant. Verify the switch port accepts SFP transceivers and that the link budget covers the required distance.

Questions about this item

Does my switch need an SFP port to accept this J4859D module?

Yes, the module plugs directly into an SFP (mini-GBIC) slot on the switch.

Can I keep my existing single-mode patch cables when I install this transceiver?

The module uses an LC single-mode interface, so your current LC single-mode patch cables will connect without change.

How do I verify the link is operating at the rated distance after installation?

Check the switch port status for a 1 Gbps link and confirm the optical power levels fall within the 1000Base-LX specification for up to 10 km.
