Detailed Specifications and Their Benefits
The module transmits and receives at 1310 nm over single-mode fibre and is specified for 1 Gbps Ethernet operation (1000BASE-LH). That wavelength and mode profile are the norm for long-distance point-to-point links, allowing predictable attenuation and margin planning across spans up to 40 km. This is particularly useful when you need Gigabit bandwidth without the expense or complexity of upgrading to 10G optics.
As a hot-pluggable SFP, the MINI-GBIC-LH40-SM1310 can be installed or removed while the host device remains powered, following vendor hot-swap procedures. Typical power consumption is ≤ 1.5 W which keeps thermal load low on switches and routers—important in dense SFP ports and power-constrained edge devices. Digital Diagnostic Monitoring (DDM/DOM) is supported, giving real-time readouts of parameters such as optical power, temperature and voltage so you can monitor link health without separate test equipment.
Physical dimensions align with the SFP MSA standard, so the module fits into any standard SFP cage. The rated operating temperature (0 °C to 70 °C) covers most indoor enterprise and data-centre environments. For deployments in extreme conditions or outdoor enclosures, validate environmental specs with the supplier or consult the full datasheet.
The transceiver is RoHS compliant and designated as a Class 1 laser device. CE/UKCA status is noted as INSUFFICIENT DATA in the provided materials, so confirm certification status with your supplier if mandatory for your market or project compliance.
Use Cases and Scenarios Where This Module Excels
- Campus backbone and building-to-building links:Connect distant buildings on a campus with a single-mode fibre run up to 40 km. The 1G capacity is often sufficient for departmental uplinks and administrative traffic.
- Data-centre interconnects (DCI) for low-to-moderate bandwidth:Use for aggregation links between closets or between nearby data-centres where 1G is adequate or when budget constraints make 10G impractical.
- Metropolitan area network (MAN) segments:Service providers or municipal networks can use this for access or aggregation segments where long reach and predictable latency matter.
- Carrier access and remote sites:Small carrier or enterprise remote sites that require a resilient single-mode connection without high port density or 10G throughput.
- Redundant or failover links:Cost-effective secondary links to provide resilience in multi-path network designs.
Comparisons with Similar Products in the Market
The MINl-GBIC-LH40-SM1310 sits squarely in the class of 1G single-mode long-haul SFPs. Compared with first-party optics from major switch vendors, branded Ruijie modules typically offer close compatibility with Ruijie gear and a lower price point than OEM originals. Against generic third-party compatibles, Ruijie-branded modules reduce compatibility risk and often provide better documentation and support.
Choosing a 1G 40 km SFP instead of a 10G option is a trade-off of cost versus throughput. 10G optics provide higher bandwidth but are more costly and consume more power. If your workload or link usage remains under 1 Gbps or you plan staged upgrades, a 1G module like the MINI-GBIC-LH40-SM1310 is a cost-effective and energy-efficient choice.
For short distances, copper (RJ45) or short-range multimode optics can be less expensive per port. However, for spans that exceed the reach of multimode or where single-mode fibre already exists, this 1310 nm SFP is the practical option. It avoids the cost of re-cabling to multimode and supports longer reach with lower attenuation.
Typical Deployment Considerations
- Compatibility:Always check the host switch/router compatibility list. While Ruijie modules are designed for wide interoperability, some vendors enforce vendor-lock checks in firmware.
- Optical budget:Verify Tx/Rx power, receiver sensitivity and fibre attenuation for your exact span. The modules support up to 40 km, but real-world reach depends on cable quality, splices and connectors.
- Handling:Observe ESD precautions, keep dust caps on until termination and follow hot-swap guidelines to avoid port errors.
Customer Feedback and Reviews
While individual reviews vary by deployment, common themes reported by network administrators and IT teams using 1G single-mode modules like the Ruijie MINI-GBIC-LH40-SM1310 include:
- Reliable long-distance links at a fraction of the cost of higher-speed optics, making them ideal for non-congested backbone segments.
- Low power draw reduced thermal load in dense switch deployments.
- DDM support provides confidence during commissioning and troubleshooting—real-time diagnostics are frequently cited as a helpful feature.
- Compatibility is generally good with modern switches; however, some users recommend confirming vendor firmware policy before purchasing for large-scale rollouts.
These points reflect aggregated feedback patterns rather than endorsements from named customers. If you require specific case studies or reference installations, request supplier-provided references or field datasheets.
Conclusion: Why Choose the MINI-GBIC-LH40-SM1310?
The Ruijie MINI-GBIC-LH40-SM1310 is a practical, well-balanced 1G SFP option for organizations that need dependable long-reach single-mode links without paying a premium for higher-speed optics. Its combination of hot-pluggability, DDM support, low power consumption and a 40 km reach makes it suitable for campus interconnects, data-centre aggregation and metro links. Price-wise it sits competitively with a suggested price of 109.99 and a cost basis of 78.72, giving network planners a transparent cost-performance option.
Before deploying, confirm any regulatory certification requirements (CE/UKCA) for your jurisdiction and validate optical budgets for the exact fibre route. For many environments—especially where existing single-mode fibre runs are already in place—the MINI-GBIC-LH40-SM1310 is a straightforward, reliable choice that delivers predictable 1 Gbps connectivity across long distances.
