Aruba-compatible 1000Base-LX SFP

This Axiom J4859D-AX transceiver delivers single-mode Gigabit Ethernet connectivity for Aruba network equipment. It operates at 1000Base-LX wavelengths through an LC duplex interface. The module is MSA compliant for broad interoperability. It suits administrators extending links up to 10 km over single-mode fibre.

RoHS compliant and lifetime warranty

The transceiver meets RoHS environmental standards for restricted hazardous substances. A lifetime limited warranty covers the module against defects. These assurances reduce long-term procurement risk for network operators. No additional software or licences are required for deployment.

Hot-pluggable LC form factor

Weighing 0.03 ounces, the SFP inserts into standard SFP ports without powering down the switch. The LC duplex connector ensures secure single-mode fibre patching. MSA compliance guarantees mechanical fit across vendor platforms. The compact design supports high-density line cards in enterprise racks.

Questions about this item

Will the LC connector on this 1000Base-LX module need periodic cleaning or replacement?

The LC single-mode interface is a passive optical component; it requires no scheduled replacement, only occasional inspection and cleaning if link loss occurs.

What distance limit applies first when the J4859D-AX runs continuously at gigabit speed?

The 1000Base-LX standard defines a maximum reach of 10 km over single-mode fibre, and that optical budget is the first constraint under sustained load.

How much power does the module draw and what heat does it add inside the switch chassis?

As an MSA-compliant SFP it operates within the standard low-power envelope, adding minimal heat and requiring no extra cooling beyond normal switch airflow.
