HPE Aruba 1G SFP LC LX Transceiver Module, 10 km Single-Mode

A 10 km gigabit link over single-mode fiber is the specification of the HPE Aruba 1G SFP LC LX Transceiver Module, part number J4859D. It operates at 1310 nm with an LC connector and fits the SFP form factor.

This module is the long-distance counterpart of the SX type. It suits links between buildings or distant wiring closets where single-mode fiber is installed and a multimode module would run out of distance. Gigabit speed is still common at the edge of campus networks, especially for uplinks from access switches.

Before ordering, confirm that the entire link is single-mode, and measure the loss on the route. Both ends need LX modules, or a module type your equipment lists as compatible.

The module has one port at 1GbE. On many switches, SFP+ cages also accept SFP modules at 1GbE, though you should check the platform documentation. Aruba switches may restrict which optics they accept, so verify support for your model.

The D at the end of the part number identifies the version of the module. If you are matching an installed module, use the exact number.

The J4859D is available in new, refurbished and used condition. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send your quantity and switch model for pricing.
