Ruijie NIS‑GE‑SFP‑550M‑MM850 — 1Gb multimode SFP optical transceiver.

• 1000BASE‑SX SFP for multimode fibre (MMF) using an 850 nm VCSEL transmitter; duplex LC connector.
• Reach up to 550 m over multimode fibre (dependent on OM grade and link conditions).
• Hot‑pluggable SFP form factor; SFP‑MSA compliant with Digital Diagnostic Monitoring (DDM/DOM).
• Low power consumption (≤ 1.5 W); transmitter (VCSEL) and PIN receiver; BER 1.0E‑12.
• Standards & safety: IEEE 802.3/1000BASE‑SR, SFF‑8472, SFF‑8431, SFF‑8432, RoHS; Class 1 laser safety.

Why choose this module?

• Branded Ruijie module offering vendor support and broad SFP interoperability for campus, datacentre and enterprise multimode links.
• DDM provides live optics diagnostics (optical power, temperature, alarm reporting) for easier fault finding and monitoring.
• Compact, hot‑swappable SFP makes upgrades and line card changes simple with minimal downtime.

Use cases: short‑reach multimode uplinks within buildings, wiring closets, access switches and server-room links where 1Gb Ethernet on MMF is required.

Installation & safety: Install only by qualified personnel. Observe ESD precautions and follow Ruijie datasheet/installation guide. Verify compatibility with your switch vendor (some vendors lock optics by vendor ID). Confirm operating temperature requirements for harsh/industrial environments prior to deployment.

Compliance note: Module meets RoHS and Class 1 laser safety; check supplier documentation for CE/UKCA markings if required for your market.
