Huawei 1310nm optical modules support speeds ranging from 1.25 Gbps up to 10.31 Gbps depending on the specific module type.

Speed Specifications

• 1.25 Gbps Modules: The Huawei ESFP 1310nm optical module supports a data rate of up to 1.25 Gbps, suitable for standard Gigabit Ethernet applications over single-mode fiber with distances up to 40 km .
• 10G Modules: Huawei SFP-10G-LR 1310nm modules support speeds from 1.25 Gbps to 10.31 Gbps, designed for 10GBASE-LR applications with a typical maximum distance of 10 km over single-mode fiber .
• Higher-Speed Options: 1310nm modules can also support 25G and 100G Ethernet in data center and enterprise backbone deployments, though these are typically specialized modules with DFB lasers for higher-speed transmission .

Applications and Considerations

• Medium-Distance Links: 1310nm modules are ideal for metro access networks, campus backbones, and data center interconnects up to 10 km, balancing cost and performance .
• Fiber Type: Single-mode fiber (SMF) is recommended for optimal performance and longer distances.
• Laser Type: FP lasers are common for 1G/2.5G modules, while DFB lasers are used for 10G and above to maintain signal integrity over longer distances .
• Network Compatibility: Ensure the module matches the switch or router interface and supports the required data rate to avoid performance issues.

Summary

Huawei 1310nm optical modules provide flexible speed options from 1.25 Gbps for standard Gigabit Ethernet to 10.31 Gbps for 10G applications, making them suitable for a wide range of enterprise, campus, and metro network deployments. Choosing the correct module depends on the required data rate, transmission distance, and fiber type.
