The HPE Aruba J4858D 1G SFP LC SX Transceiver is a high-performance, cost-effective optical module designed to deliver 1 Gigabit Ethernet connectivity across multimode fiber (MMF) links. Perfect for enterprise, campus, and data center networks, this transceiver ensures fast, reliable, and energy-efficient data transmission.
Engineered to meet the IEEE 802.3z 1000BASE-SX standard, the J4858D operates at an 850 nm wavelength and supports data transmission distances up to 550 meters (1804 feet) over OM2/OM3 multimode fiber. It features an LC duplex connector for easy installation and integration with Aruba and HPE networking devices such as switches, routers, and network adapters.
With its hot-swappable SFP form factor, the J4858D enables seamless deployment and replacement without service interruption. It also supports Digital Diagnostic Monitoring (DDM/DOM) for real-time tracking of temperature, voltage, laser bias, transmit power, and receive power — helping IT administrators maintain peak performance and minimize downtime.
Compact, efficient, and reliable, the Aruba J4858D transceiver is optimized for short-range fiber applications such as switch-to-switch uplinks, server connections, and high-speed LAN segments.
