BlueOptics J4858D-BO HPE Aruba J4858D Compatible SFP Transceiver 1000BASE-SX 850 nm LC Multimode 550 m DDM
BlueOptics J4858D-BO — HPE Aruba J4858D-Compatible 1G SX SFP
The BlueOptics J4858D-BO is a Gigabit SFP transceiver for multimode fibre, coded to identify as an HPE Aruba J4858D: 1000BASE-SX at 850 nm over an LC duplex connection, up to 550 m, with digital diagnostics. It is the BlueOptics BO05C856S5D module, a lower-cost way to add or replace SX optics in HPE Aruba and ProCurve switches that check the optic code. In practice, multimode optics are the cheaper choice for links inside one building: most server rooms and floor risers already carry multimode fibre, and the module plus a short LC patch cord is all a port needs. Before you order, check the fibre grade printed on the cable jacket and the real length of the run, including patch panels.
