SFP transceiver modul Ruijie Networks NIS-GE-SFP-550M-MM850 1000 Mbit/s 850 nm

The Ruijie Networks NIS-GE-SFP-550M-MM850 SFP transceiver module is designed for multimode fiber links delivering up to 1000 Mbit/s at an 850 nm wavelength. It is a compact, hot-pluggable optical module intended to provide a physical interface between networking equipment and multimode fiber cabling, enabling short-range Gigabit Ethernet connections in data centers, access networks, and enterprise switches.

Advantages

This SFP transceiver offers standardized compatibility with devices that accept SFP form-factor modules and supports reliable 1 Gbit/s throughput over multimode fiber. Its 850 nm VCSEL-based optics enable energy-efficient transmission for short-distance links while maintaining low latency and error performance. The module's compact SFP housing and hot-pluggable capability simplify installation and replacement without powering down connected equipment.

Suitable for

• Short-range Gigabit Ethernet links over multimode fiber (data centers, server racks)
• Access layer connections in enterprise network switches and routers
• Fiber uplinks between floor switches or distribution cabinets
• Network equipment testing and lab environments

Key specifications

• Data rate: up to 1000 Mbit/s (1 Gbps)
• Optical wavelength: 850 nm
• Fiber type: multimode fiber (MM)
• Transmission distance: suitable for short-reach multimode links (typical up to several hundred meters depending on fiber type and grade)
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Connector type: duplex LC (industry-standard for multimode SFP optics)

How to use

Install the SFP module into an available SFP port on a compatible switch, router, or transceiver cage, ensuring the module is fully seated until it clicks. Connect duplex LC multimode fiber patch cables to the module’s optical ports, observing proper transmit/receive orientation. Verify link status on the host device and configure the corresponding network interface to the required speed and duplex settings if necessary. Use proper electrostatic discharge precautions when handling the module and protect the optical interfaces with dust caps when not in use.

Recommendations

Use multimode fiber of appropriate grade (OM1/OM2/OM3/OM4) to match required distance and performance; for longer runs, consider single-mode optics. Confirm compatibility with the host device’s supported SFP modules and consult vendor documentation for any platform-specific settings. Keep connector endfaces clean and avoid bending fibers beyond recommended radii to maintain signal integrity.
