Introduction to the Ruijie NIS-GE-SFP-10KM-SM1310 and its key features
The Ruijie NIS-GE-SFP-10KM-SM1310 is a compact, hot-pluggable SFP transceiver built for reliable 1 Gbps single-mode fibre links. Designed to support 1000BASE-LX connections, this module transmits at 1310 nm and uses a duplex LC connector to achieve reach up to 10 km over 9/125 µm single-mode fibre. Its support for Digital Diagnostic Monitoring (DDM/DOM), standard +3.3 V power supply and RoHS compliance make it a practical choice for enterprise, campus and industrial deployments where predictable optical performance and easy maintenance are required.
Detailed product specifications and benefits
Understanding the technical specifications helps explain why this SFP is a useful building block in many networks. The key specifications are:
- Form factor and compatibility:SFP (mini-GBIC), hot-pluggable, fits standard SFP ports on switches and routers that accept third-party modules. Model references include NIS-GE-SFP-10KM-SM1310 and RG-NIS-GE-SFP-10KM-SM1310.
- Optical standard and data rate:1000BASE-LX, supporting up to 1.25 Gbps PHY rate (commonly used as 1 Gbps Ethernet).
- Wavelength and connector:1310 nm transmit/receive with a duplex LC connector for single-mode fibre.
- Reach:Up to 10 km over 9/125 µm single-mode fibre — ideal for short to medium single-mode runs between buildings or across a campus.
- Diagnostics:DDM/DOM supported, enabling real-time monitoring of parameters like optical output power, input power, temperature and supply voltage. This simplifies troubleshooting and proactive maintenance.
- Power and compliance:Standard +3.3 V supply and RoHS compliance. CE/UKCA and warranty details can vary by supplier or SKU—confirm with your reseller.
- Environmental options:Commercial and reported industrial/extended temperature variants exist; industrial variants typically cover roughly −40°C to +85°C while commercial modules usually operate from 0°C to +70°C. Always verify the exact operating range for the unit you buy.
Benefits of these specifications include predictable single-mode performance for point-to-point links, straightforward hot-swap replacement, and the ability to monitor link health via DDM without extra hardware. The duplex LC form factor is widely used and offers a compact, robust connection that fits modern networking gear.
Use cases and scenarios where this module excels
The Ruijie 10 km 1Gb LC SFP is tailored for a range of practical deployments where single-mode fibre is preferred or already installed.
- Campus and enterprise uplinks:Use these SFPs for switch-to-switch uplinks between buildings on the same campus where distances are under 10 km. They are ideal when fibre backbone runs use single-mode cabling.
- Building-to-building connections:For facilities separated by streets or several hundred metres up to a few kilometres, this module provides a simple, cost-effective method to extend your LAN without needing media converters.
- Industrial Ethernet links:Where industrial temperature options are required, the industrial variant of this module can keep networked control systems and remote sensors connected across fibre runs in harsh environments.
- ISP and edge links:For edge devices or small ISP customer aggregation points where 1 Gbps single-mode links are sufficient, the module gives an economical, low-power option for long-reach links.
- Security and CCTV backhaul:High-quality video feeds from remote cameras can be aggregated and transported over single-mode fibre to a central monitoring station using these SFPs.
In each scenario the module’s hot-pluggability and DDM support reduce downtime and speed diagnostics — a crucial advantage when uptime matters.
Comparisons with similar products in the market
When choosing an SFP transceiver, common alternatives include multimode SFPs (1000BASE-SX), copper Gigabit modules (1000BASE-T), and higher-speed optics such as SFP+ 10G modules. Here’s how the Ruijie 1310 nm 10 km module compares:
- Single-mode (1000BASE-LX) vs multimode (1000BASE-SX):Multimode SFPs operate at shorter wavelengths (850 nm) and shorter distances on multimode fibre (typically up to 550 m depending on fibre grade). If your cabling is single-mode or your run exceeds multimode limits, the Ruijie LX module is the correct choice. Multimode can be cheaper for very short runs and uses cheaper optics overall, but it cannot match single-mode reach.
- Optical vs copper (1000BASE-T):Copper (RJ45) SFPs are convenient for short runs and avoid fibre handling, but are limited by EMI and distance (100 m). They consume more power and are heavier on switches that must drive copper. The Ruijie single-mode SFP provides electrical isolation, longer reach, and immunity to electromagnetic interference — important in industrial or outdoor installations.
- 1G SFP vs 10G SFP+:For sites needing higher throughput, SFP+ 10G modules are available, but they require compatible ports and often cost more. If your traffic needs are within 1 Gbps per link, the Ruijie module offers an economical balance of cost, power and reach.
- Brand and compatibility considerations:Many vendors produce 1000BASE-LX SFPs with similar specifications. What differentiates modules are vendor compatibility, warranty, environmental tolerance and price. The Ruijie module is positioned as a reliable OEM/partner-friendly option; as with any third-party SFP, verify that your switch or router accepts non-vendor transceivers and check any vendor-specific compatibility notes.
Customer testimonials and practical feedback
While individual experiences vary by environment and installer, typical feedback themes for this class of SFP include:
- Ease of installation:Technicians appreciate the hot-pluggable form factor and the standard LC interface that fits neatly into existing racks and patch panels.
- Diagnostics:Users who enable DDM note faster fault isolation because real-time optical metrics (power, temperature, voltage) are available through the switch CLI or management GUI.
- Value for money:For organisations that need reliable 1 Gbps single-mode links without paying a premium for 10G optics, the module’s price point is often cited as competitive.
- Compatibility caution:A common piece of advice from installers is to check compatibility lists and firmware versions for certain vendors’ equipment to avoid unexpected link-down conditions when using third-party SFPs.

Installation tips, safety and warranty considerations
To get the most from this module and avoid damage:
- Observe electrostatic discharge (ESD) precautions when handling the SFP.
- Keep optical ports capped when not connected to protect the transmitter/receiver from contamination and damage.
- When inserting or removing SFPs, follow the equipment vendor’s hot-swap guidance; although hot-pluggable, some platforms recommend staged procedures to avoid transient issues.
- Verify the operating temperature range (commercial vs industrial) and warranty details with your supplier before purchase — packaging and SKU definitions can affect warranty and compliance markings such as CE/UKCA.
Conclusion: why the Ruijie NIS-GE-SFP-10KM-SM1310 is a great choice
For administrators and integrators seeking a straightforward, economical and diagnostic-capable 1 Gbps single-mode transceiver, the Ruijie NIS-GE-SFP-10KM-SM1310 is a strong candidate.
