## Summary description

BlueOptics J4858D-BO is a fiber optic SFP transceiver supporting up to 1250 Mbit/s data rate at 850 nm wavelength. Designed for hot-pluggable SFP interfaces, it enables short-range optical links in switches and routers. Compact silver module weighing 20 g, suitable for upgrading or replacing SFP ports to provide reliable optical connectivity in LAN environments.

## Long description

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.
Suitable for
1 Gbit/s Ethernet connections over multimode fiber
Fibre Channel over Ethernet and SDH/SONET applications up to 1.25 Gbit/s
Integration into HPE Aruba-compatible switches, routers and storage systems
Short- to medium-range fiber links up to 550 m (MMF)
Key specifications
Product name: BlueOptics J4858D-BO
Form factor: SFP (LC duplex)
Wavelength: 850 nm (Tx/Rx)
Maximum data rate: 1250 Mbit/s (1.25 Gbit/s)
Maximum reach: up to 550 m on multimode fiber
Compatibility: HPE Aruba J4858D-compatible (MSA compliant)
Product colour: Silver; Weight: 20 g
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.
Usage 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.
