Instantly boost your data center and campus network with the Ruijie XG-SFP-SR-MM850 – a high-performance 10GBASE-SR SFP+ transceiver built for short-reach multimode fiber deployments. Fully compliant with IEEE 802.3ae and SFP+ MSA standards, this hot-pluggable module delivers blazing-fast 10.3125 Gbps over OM3/OM4 fiber up to 300 m (OM3) or 400 m (OM4), and 82 m on OM2 – perfect for high-density rack-to-rack, top-of-rack to server, and horizontal cabling in enterprise and cloud environments.
Powered by a reliable 850 nm VCSEL laser and PIN receiver, it offers low power consumption (< 1 W), excellent jitter performance, and a 4.5 dB link budget. The duplex LC connector ensures quick, secure installation, while real-time Digital Diagnostic Monitoring (DDM/DOM) provides instant visibility into temperature, voltage, laser bias, and Tx/Rx optical power directly from your switch GUI.
Zero configuration – just plug into any Ruijie or MSA-compliant SFP+ port and it works. Commercial temperature range (0°C to 70°C) and Class 1 laser safety make it ideal for busy data centers. Cost-effective and fully tested for Ruijie switches, it’s the smart choice for upgrading from 1G to 10G without replacing existing multimode cabling.
