Aruba J9151E — 10G SFP+ LR optic for single-mode links up to 10 km

What it is: Aruba’s 10GbE SFP+ Long-Reach (LR) transceiver. It plugs into any Aruba switch/router that supports 10G SFP+ and gives you 10G over single-mode fiber for campus/backbone runs.

Why buyers pick J9151E (plain English)

• The standard 10G “long run” optic: ideal when SR’s ~300m just isn’t enough.

• Simple, reliable SMF backbone: great for IDF↔MDF, building-to-building, or long risers.

• Pretty universal in Aruba land: a common go-to for CX/ProCurve 10G SFP+ uplinks.
