HP J9144A Hewlett-Packard HP ProCurve networking / enterprise server hardware Datacentre Switch

The HP J9144A is a ProCurve Switch 10GbE X2-SC LRM optical transceiver, an X2 form-factor module for HP’s older zl-series 10-Gigabit uplink modules that use X2 rather than the later SFP+ optics. The LRM (Long Reach Multimode) designation means it’s designed to run 10GBASE-LR-class optics over legacy multimode fibre runs up to around 220 metres using electronic dispersion compensation circuitry, rather than requiring a fibre plant upgrade to single-mode for longer 10-Gigabit runs. It uses SC-type fibre connectors, an older connector style than the LC connectors used on most later 10-Gigabit optics. Buyers should confirm their specific zl-series 10GbE X2 module supports LRM optics (not all X2 slots on every HP platform do) before ordering, and that the existing multimode fibre run is within LRM’s supported distance and quality specification. Tech-Star (UK-based, shipped worldwide) supplies ProCurve X2 optics for ongoing zl-series maintenance.
