Fiber optic SFP transceiver BlueOptics J4858D-BO, 1250 Mbit/s, 850 nm, silver

The BlueOptics J4858D-BO is a 1000Base-SX SFP fiber optic transceiver compatible with HPE Aruba J4858D modules. It uses an LC duplex connector and operates at 850 nm for both transmitter and receiver, supporting multimode fiber links. The module follows MSA standards and supports data rates up to 1.25 Gbit/s over distances up to 550 meters, suitable for use in switches, routers, storage systems and other network hardware that accept the original HPE Aruba J4858D SFP.

Advantages

This BlueOptics module is tested for compatibility with major HPE Aruba platforms and adapted to meet required software and hardware interfaces. It is manufactured to MSA standards using selected components from established suppliers, providing reliable signal performance and an extended operational lifetime. The module offers the same functional characteristics as the original HPE Aruba J4858D SFP while delivering a cost-effective alternative for standard multimode fiber Ethernet and Fibre Channel over Ethernet applications.

Key specifications

How to use

Insert the SFP module into a compatible SFP port on the switch, router or storage device while the equipment is powered according to the vendor's guidance. Connect LC duplex multimode fiber patch cords to the Tx and Rx ports, ensuring correct polarity. Verify link status in the device management interface and configure network settings as required for Ethernet or Fibre Channel over Ethernet operation. Follow standard electrostatic discharge (ESD) precautions when handling the module.

Recommendations

Use this module in hardware platforms that explicitly support HPE Aruba J4858D SFPs or MSA-compatible SFPs. For stable links, use OM2/OM3/OM4 multimode fiber and keep patch cord connections clean. If interoperability or firmware checks are required, test the module in a non-critical segment before deployment.
