SFP Transceiver for HP Networks

This AddOn J4859C-AO transceiver plugs into a Gigabit Ethernet SFP slot and links the port to a single-mode fibre network. It operates at a 1310nm wavelength and delivers a 1 Gbps transfer rate over distances up to 10 km. The module uses an LC connector and is factory loaded with OEM specific configuration data for HP compliance. It is a hot-swappable input/output device designed for reliable connectivity.

Suits HP Gear Needing 10 km Reach

Network administrators maintaining HP switches or routers that require the J4859C or J4858B part numbers can deploy this module directly. It initialises and performs identically to the original OEM transceivers and can be mixed with other OEM or third-party units. Buyers who need multimode fibre links limited to 550 m or who require DOM monitoring support should look at a different module.

1310nm Single-Mode 10 km Specification

The decisive specification is the 1310nm wavelength combined with a 10 km reach on single-mode fibre. This LX transceiver type defines the exact fibre plant and distance the link will support. Confirm the HP equipment accepts this specific OEM configuration before purchase.

Questions about this item

What comes in the box and do I need to buy any cables separately?

The transceiver module is supplied on its own; you must provide your own single-mode fibre patch cables with LC connectors to complete the link.

How do I choose between the listed part numbers J4859C and J4858B?

This module replaces the HP J4859C 1000Base-LX part; J4858B is a different HP SKU and is not directly replaced by this unit.

What does the 10 km reach mean once the module is installed in a switch?

It guarantees a 1 Gbps full-duplex link over single-mode fibre up to 10 km at the 1310 nm wavelength when paired with a compatible LC patch cord.
