Huawei SFP+ optical modules are compatible with both 10 Gigabit and 1 Gigabit speeds, depending on the switch port and module type.

Compatibility Overview

Huawei offers a range of optical modules including SFP, SFP+, XFP, and SFP28, each designed for specific speed ranges and applications.

SF

P modules typically support 1 Gigabit Ethernet (1. 25 Gbps) and are widely used in access and aggregation layers. SFP+ modules support 10 Gigabit Ethernet (up to 10.

31 Gbps) but can also accept SFP modules in the same port, allowing operation at 1G speeds if the switch supports dual-rate functionality. Huawei SFP+ modules, such as the SFP+10GE-LH10-SM1310, are designed to operate over single-mode fiber and support 1. 25–10.

31 Gbps, making them versatile for both 1G and 10G applications.

Practical Considerations

Port Compatibility: SFP+ ports on Huawei switches generally accept SFP modules, but the speed may be locked at 1G until the switch is rebooted or configured.

Auto-

Negotiation: Fiber-based SFP/SFP+ modules do not support auto-negotiation. Therefore, the link speed must be manually configured to match the module and port capabilities. Economic and Network Planning: While a 10G SFP+ module can operate at 1G when connected to a 1G SFP module, it is often more cost-effective to use a 1G module for 1G links to avoid unnecessary over-provisioning.

Summary

Huawei optical modules provide flexible speed compatibility: SFP+ modules can operate at 10G for high-speed links and can also support 1G when paired with compatible SFP modules and properly configured ports. Users should verify switch model support for dual-rate operation and configure the link speed accordingly to ensure seamless connectivity.
