Q & A

HPE J4858C is an Aruba X121 1G SFP LC SX Transceiver. It belongs to the Aruba Transceiver range. The part number is the reliable way to identify it, because accessories of this kind are often visually identical across generations that are not interchangeable.

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. Tell us the chassis or model it has to work with and we will confirm the part before anything ships. Quotes go out the same or next working day.
