Aruba compatible J4858A Description
EdgeOptic's J4858A 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.
J4858A is the base ordering code in the HP ProCurve X121 Gigabit-SX-LC SFP line, the oldest revision of this 1G SX part. Later revisions such as J4858C and J4858D are coded for newer HP and Aruba platform generations; each is its own ordering code, so match the exact part number your switch documents rather than assuming the revisions are interchangeable. EdgeOptic codes the EEPROM with ProCurve-recognized J4858A data so the module identifies correctly on legacy HP ProCurve platforms. Verify your exact switch model and firmware against HP or Aruba'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.
Frequently Asked Questions
Will the J4858A compatible be accepted by HP and Aruba switches without extra configuration?
EdgeOptic codes the module's EEPROM with ProCurve-recognized J4858A data so it identifies correctly as a 1000BASE-SX SFP. Acceptance of third-party optics still depends on the switch: some HP and Aruba switches document their own transceiver policy and command for non-original modules, so verify the behavior for your specific switch model and firmware in HP or Aruba's documentation. For a compatibility check against your platform, contact our sales team.
