Aruba compatible J4858B Description

EdgeOptic's J4858B compatible is an HP (Aruba)-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850nm VCSEL transmitter and a PIN photodiode receiver.

With a 7.5 dB optical budget, the module reaches 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m over OM1 (62.5/125). It uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live monitoring of optical power, bias current, and temperature. The module operates over the commercial 0 to 70°C range, built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.

J4858B is the ProCurve Gigabit-SX-LC ordering code for this 1G SX SFP, and it is the -B revision in the HP ProCurve X121 1G SX product line. EdgeOptic codes the EEPROM with HP-recognized data so the module is accepted on HP and Aruba platforms. It works in legacy ProCurve chassis and mini-GBIC interface modules of the ProCurve xl, vl, gl, cl, yl, and zl generations; verify your exact switch model and firmware against HPE's transceiver compatibility guide before ordering.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ordering-code confirmation or platform questions, contact our sales team.
