The AddOn J4858B-AO is an HP J4858B-compatible 1Gbps 1000Base-SX SFP transceiver for network teams connecting switches or other compatible equipment over multimode fiber, with an LC connector and reach up to 550m at 850nm.
Recommended For
- Network administrators adding a 1-Gigabit fiber uplink between HP/ProCurve switches, when the switch model and firmware support this compatible SFP.
- IT teams connecting switches or network equipment in the same building over existing multimode fiber with LC connectors, for links within the product’s listed 550-meter reach.
- Organizations maintaining HP ProCurve installations that need a 1-Gigabit, 1000BASE-SX replacement module and can verify the compatible SFP against their specific switch.
- Procurement teams sourcing a compatible SFP for a project that calls for a TAA-listed product; confirm that the listing and vendor documentation meet the project’s specific requirements.
Real-World Use Scenarios
- Link two compatible switches in separate wiring closets using existing multimode fiber; with matching SX optics at both ends, the connection provides a Gigabit Ethernet fiber uplink without running new copper.
- Add a fiber uplink from an older HP ProCurve access switch to a compatible upstream switch when the site already has multimode cabling; the J4858B is listed for supported HP switch families, but confirm compatibility for both devices before installation.
- Replace a failed or missing J4858B-compatible optic in a supported HP switch while keeping the existing LC multimode-fiber link; the replacement can restore the link if the switch, fiber type, and optic at the other end are compatible.
- Connect switches in different rooms or across floors where multimode fiber is already installed; the link can span more distance than a typical copper Ethernet run, with the usable reach depending on the fiber grade and link conditions.
