The HP J4859B is a ProCurve Gigabit-LX-LC Mini-GBIC, a 1000Base-LX transceiver with an LC duplex connector for single-mode fibre runs of up to around 10 kilometres (and usable over multimode fibre for shorter distances with a mode-conditioning patch cord). It fits the mini-GBIC slots on ProCurve GL, XL and zl-series switches and modules, and is intended for longer building-to-building or campus fibre links than a short-reach SX transceiver can support. This is the correct spare for restoring a failed long-reach Gigabit fibre uplink or for adding a fibre port to an existing single-mode fibre installation. Specifiers should confirm their fibre type and link distance before ordering, since an LX transceiver on multimode fibre without a mode-conditioning patch cord can give unreliable results at longer distances. Tech-Star (UK-based, shipped worldwide) sources and tests refurbished HP parts like this one to keep ProCurve fibre installations running past end of manufacturer support.
