The HP J4858A is a ProCurve Gigabit-SX Mini-GBIC transceiver, a fibre optic module that fits into a mini-GBIC (SFP) slot on compatible ProCurve switches and chassis modules to provide a 1000Base-SX multimode fibre uplink or access port. It is used wherever a ProCurve deployment needs a fibre connection over multimode cabling rather than copper, typically for building or short campus interconnects within the SX standard’s reach. As a transceiver rather than a switch or module in its own right, it is one of the most routinely replaced components in a ProCurve fibre deployment, needed whenever an existing SX link is being extended, restored after a failed transceiver, or a new fibre port is being brought into service. Specifiers should confirm mini-GBIC slot compatibility with their specific ProCurve host switch before ordering. Tech-Star (UK-based, shipped worldwide) stocks HP ProCurve components to support ongoing network maintenance projects. Please contact our sales team for current stock and pricing.
