Power your high-speed short-range fiber connections with the Ruijie MINI-GBIC-SX-MM850 – a reliable 1G SFP transceiver engineered for seamless 1000BASE-SX Gigabit Ethernet performance. Fully compliant with IEEE 802.3z and SFP MSA standards, this hot-pluggable module delivers 1.25 Gbps data rates over multimode fiber (MMF) up to 550 meters (OM2) or 275 meters (OM1) – perfect for data centers, server rooms, campus backbones, and building-to-building links where low latency and high bandwidth are essential.
Operating at 850 nm with a VCSEL laser transmitter and high-sensitivity PIN receiver, it guarantees excellent signal integrity and low power consumption. The duplex LC connector ensures fast, secure connections, while real-time Digital Diagnostic Monitoring (DDM/DOM) tracks critical parameters like optical power, temperature, and voltage directly from your switch or router interface.
Plug-and-play compatibility with all Ruijie switches and routers, plus full MSA compliance, makes it an ideal drop-in replacement or upgrade. Rugged commercial-grade design (0°C to 70°C) and Class 1 laser safety rating provide worry-free deployment in busy IT environments.
Upgrade your short-haul Gigabit infrastructure instantly – no downtime, no configuration headaches. The Ruijie MINI-GBIC-SX-MM850 delivers rock-solid performance at a fraction of the cost of big-name brands.
