Product Overview
The Ruijie XG-SFP-SR-MM850 is a 10GBASE-SR SFP+ optical transceiver designed for short-range 10 Gigabit fibre uplinks over multimode fibre. It operates at an 850nm wavelength and supports link distances of up to 300m over OM3 fibre or up to 400m over OM4 fibre, using a duplex LC connector. This Ruijie XG-SFP-SR-MM850 10G SFP+ module is well suited to switch-to-switch uplinks, aggregation links, rack-to-rack connections, data cabinets, CCTV network backbones and business fibre upgrades where multimode fibre is already installed. It is best selected when the network needs a reliable 10G optical link over MMF, rather than a longer-distance single-mode LR, ER or ZR optic.
Key Capabilities
10G Short-Range Fibre
The XG-SFP-SR-MM850 supports 10.3125Gbps transmission, making it suitable for high-speed switch uplinks and short-range backbone links where a standard 1G fibre connection is no longer enough.
Multimode Fibre Support
This module is designed for multimode fibre installations, supporting up to 300m over OM3 or up to 400m over OM4 fibre. It is ideal for short-distance fibre links inside buildings, cabinets and campuses.
850nm 10GBASE-SR Optics
The 850nm wavelength and 10GBASE-SR specification make this transceiver a standard choice for short-reach multimode 10G links, helping installers match optics correctly to existing MMF cabling.
Duplex LC Connection
The duplex LC interface uses separate transmit and receive fibre strands, making it suitable for common structured multimode fibre patching in network cabinets, equipment rooms and rack environments.
SFP+ Form Factor
The compact SFP+ form factor fits compatible 10G SFP+ ports on supported Ruijie switches and networking equipment, giving installers a clean optical uplink option for 10G fibre designs.
Best For
- Short-Range Switch Uplinks: Suitable for connecting compatible Ruijie switches over 10G multimode fibre.
- Rack-to-Rack Connections: A practical choice for links between network cabinets, server racks or equipment rooms within the same building.
- CCTV Aggregation Networks: Useful where multiple camera switches aggregate back to a core or NVR network over a short 10G fibre uplink.
- Office and Campus Backbones: Ideal for internal fibre runs between floors, communications rooms or nearby buildings using compatible multimode fibre.
- Existing MMF Installations: Best when the site already has OM3 or OM4 multimode fibre with duplex LC termination.
Why Choose the XG-SFP-SR-MM850
Choose the XG-SFP-SR-MM850 when the installation needs a standard 10G multimode fibre transceiver for short-reach switch uplinks or internal backbone links. Compared with LR single-mode optics, this SR module is better suited to shorter multimode fibre runs commonly found inside buildings, racks and communications rooms. It is also more appropriate than copper Ethernet where distance, electrical separation or fibre infrastructure makes optical cabling the cleaner option. This model, supplied by Security Wholesalers, suits professional Ruijie network deployments where the fibre type, link distance, connector type and SFP+ compatibility need to be matched correctly before installation.
Buyer Decision Tips
Buyer Tip: Confirm that the connected device has a compatible 10G SFP+ port before ordering. This transceiver is not for RJ45 copper Ethernet ports and should not be selected for equipment that only supports 1G SFP modules unless compatibility is confirmed.
Buyer Tip: Match the cable type carefully. The XG-SFP-SR-MM850 is designed for multimode fibre, not single-mode fibre. For single-mode 10km links, choose a compatible LR module instead.

Choosing the Right Model
- Choose this model if: You need a 10GBASE-SR SFP+ 850nm transceiver for duplex LC multimode fibre links up to 300m on OM3 or 400m on OM4.
- Choose an LR module if: The site uses single-mode fibre or needs a longer 10km-style fibre link.
- Check before ordering: Confirm SFP+ port support, multimode fibre type, LC connector availability, required link distance and compatible optics at both ends of the link.
FAQs
- What is the XG-SFP-SR-MM850 used for?
The XG-SFP-SR-MM850 is used to create short-range 10G fibre links between compatible network devices with SFP+ ports. It is commonly used for switch uplinks, rack-to-rack links, aggregation connections and internal fibre backbone upgrades where multimode fibre is already installed.
- What fibre type does the XG-SFP-SR-MM850 require?
The XG-SFP-SR-MM850 is designed for multimode fibre, not single-mode fibre. It uses a duplex LC connector and operates at 850nm. Buyers should confirm whether the installed fibre is OM3 or OM4 multimode fibre before ordering, because the cable type affects supported link distance.
- How far can the XG-SFP-SR-MM850 transmit?
The XG-SFP-SR-MM850 supports up to 300m over OM3 multimode fibre or up to 400m over OM4 multimode fibre. Actual link performance depends on cable quality, patching, connector cleanliness, bend radius and compatible optics at both ends of the connection.
- Is the XG-SFP-SR-MM850 suitable for single-mode fibre?
No. The XG-SFP-SR-MM850 is an SR multimode fibre transceiver. For single-mode fibre, a compatible LR module such as a 1310nm 10km optic is usually the correct choice. A common mistake is choosing by connector type alone while overlooking fibre type and wavelength.
- Does this module work in standard RJ45 Ethernet ports?
No. The XG-SFP-SR-MM850 is an SFP+ optical module and must be installed into a compatible SFP+ slot. It is not designed for RJ45 copper Ethernet ports, and it should not be selected for equipment that only supports 1G SFP modules unless the device compatibility is specifically confirmed.
- What connector does the XG-SFP-SR-MM850 use?
The XG-SFP-SR-MM850 uses a duplex LC connector, which requires separate transmit and receive fibre strands. This connector type is common in structured multimode fibre environments. Buyers should check patch lead type, fibre polarity and the connector requirements at both ends of the link.
- Should I buy one or two XG-SFP-SR-MM850 modules?
Most fibre links require a compatible optical transceiver at both ends. If connecting two compatible switches over multimode fibre, you will usually need one module for each switch. This model is available through Security Wholesalers for suitable Ruijie 10G multimode fibre uplink deployments.
- What should I check before installing the XG-SFP-SR-MM850?
Before installation, confirm the connected equipment supports 10G SFP+, the fibre is multimode, the connector is duplex LC, the link distance is within the supported OM3 or OM4 range, and the far-end optic is compatible. Clean fibre connectors are also important for stable 10G links.
