The HP J4131B is a ProCurve Gigabit-SX transceiver, a 1000Base-SX optical module for multimode fibre runs up to around 550 metres, fitting the transceiver slots on ProCurve GL and XL-series chassis modules built for this transceiver format. It is a short-reach optical module intended for building or campus-level fibre links rather than long-haul spans, commonly used for switch-to-switch uplinks or fibre-attached servers within a single site. This is the correct spare for restoring a failed Gigabit fibre uplink on compatible chassis hardware. Specifiers should confirm their chassis module’s transceiver format and required connector type before ordering, since ProCurve used more than one transceiver connector standard across this hardware generation. 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.
