J4858D — Aruba 1G SFP LC SX 550m MMF xcvr

The J4858D is an HPE Aruba 1 Gigabit SFP module on multimode fiber, compliant with the 1000BASE-SX standard. Fitted with an LC duplex MMF connector, it delivers a maximum reach of 550 m — sufficient for virtually all horizontal or vertical intra-building links over OM1/OM2/OM3 fiber. Its thermal range of 0 to 70 °C ensures reliability in standard network racks.

The J4858D is the cost-effective choice for private deployments (outside regulated markets) where the TAA-certified JL745A is not required. It suits SMEs and secondary datacenters operating on existing multimode fiber who need reliable Gigabit SFP ports. Genuine hardware, manufacturer warranty.
