HPE Aruba J4858D 1G SFP LC SX Transceiver – Gigabit Ethernet Multimode Fiber Module, 850nm, up to 550m

HPE J4858D is a 1G SFP SX Transceiver supporting Multimode Fiber up to 550m, ideal for reliable enterprise network connectivity. Go by the part number. Items like this are routinely identical to look at and specific in what they actually fit.

Matching the port. Check the form factor, the data rate and the reach against the port you are fitting, and the wavelength where the link is single-fibre or wavelength-division. Reach figures assume a loss budget: a 10 km optic will not reach 10 km through a patch panel with dirty connectors, so allow margin. Some switches also restrict which optics they will accept.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. If you are unsure whether this is the right part, give us the model it is going into and we will confirm it. Quotes by the next working day.

The HPE Aruba J4858D is a high-performance 1 Gigabit SFP (Small Form-factor Pluggable) transceiver module designed for short-range data communication over multimode fiber (MMF). It delivers reliable and cost-effective connectivity for enterprise networks, data centers, and campus environments.

Operating at a wavelength of 850nm, the J4858D supports distances of up to 550 meters over OM2/OM3 multimode fiber, making it ideal for intra-building and short-distance interconnection between switches, routers, and servers.

This transceiver provides Gigabit Ethernet (1GbE) performance, ensuring stable and high-speed data transmission for critical network operations. It is fully compatible with a wide range of HPE Aruba switches and networking devices, and also supports industry-standard SFP interfaces for interoperability with other vendors’ equipment.
