HP J4859C Compatible SFP Transceiver

This Array J4859C-AR module provides a direct replacement for the HP J4859C 1000base-LX GBIC SFP. It is built for network administrators who need a standards-compliant link over single-mode fibre. The unit carries MSA, RoHS and IEEE 802.3z compliance.

Verify Single-Mode Fibre and 1310nm Wavelength

Before ordering, confirm that your existing cabling plant uses single-mode fibre terminated with LC connectors. The link budget requires a 1310nm wavelength on both ends. Ensure the host switch or router accepts MSA-compliant SFP transceivers and supports the 1000base-LX standard.

Hot-Pluggable Module Frees a Switch Port

The transceiver inserts into any standard SFP slot without powering down the chassis, instantly adding a long-range uplink. It connects campus buildings or data-centre rows over single-mode fibre while leaving copper ports free for short-run connections. No additional configuration is required beyond the port enable command.

Questions about this item

Does the J4859C-AR transceiver ship with any cables or patch cords?

The module is supplied on its own; single-mode fibre patch cords with LC connectors must be purchased separately.

Is the J4859C-AR the right choice for a 1000base-LX link over single-mode fibre?

Yes, it operates at 1310 nm and complies with IEEE 802.3z for 1000base-LX on single-mode fibre.

What distance can I expect from the 1310 nm wavelength in a typical gigabit link?

At 1310 nm the transceiver supports standard 1000base-LX reach on single-mode fibre, typically up to several kilometres.
