The StarTech.com J4858CST is an HPE J4858C-compatible 1000BASE-SX SFP transceiver for HPE switches and other compatible SFP hosts, connecting 1GbE equipment over multimode fiber for distances up to 550 m.
Recommended For
- HPE switch owners replacing a failed or damaged J4858C-class optic in a compatible SFP port, especially on the listed 1400, 1700, 1820, 2520, or 2530 series.
- Network administrators extending a 1GbE connection between switches or network segments over existing duplex multimode fiber, when the host supports the module and the fiber run fits the link budget.
- Home-lab and small-network builders using HPE or compatible MSA SFP equipment who want to test a third-party optic and can verify that their specific switch recognizes it.
- IT teams that want a hot-swappable 1GbE multimode optic with digital diagnostics for checking transceiver status through supported network-management tools.
