25GbE provides substantially more bandwidth than 10GbE and is widely used for server uplinks, switch interconnections and high-performance data-center networking.
SFP28 Form Factor
The Huawei SFP-25G-SR uses the compact SFP28 form factor. SFP28 modules are designed for 25Gbps Ethernet applications while maintaining a compact pluggable design suitable for high-density network switches and adapters.
The SFP28 form factor is particularly useful where network equipment requires a large number of high-speed ports within a limited rack-space footprint.
25GBASE-SR Standard
The SFP-25G-SR supports the 25GBASE-SR application standard. SR stands for Short Reach and is intended for short-distance transmission over multimode optical fiber.
This makes the module well suited to data-center deployments where network equipment is connected over relatively short fiber runs.
850nm Optical Wavelength
The SFP-25G-SR operates at an 850nm center wavelength. Huawei's official specification identifies 850nm as the transmitter center wavelength. :contentReference[oaicite:3]{index=3}
The 850nm wavelength is commonly used for short-range multimode-fiber Ethernet applications.
Multimode Fiber Support
The module is designed for multimode fiber (MMF). Huawei specifies OM3 and OM4 multimode fiber transmission distances for this module. :contentReference[oaicite:4]{index=4}
Using the appropriate fiber grade and connector is important for achieving the expected transmission distance and link performance.
Transmission Distance
Huawei's official specifications list the following target distances:
| Fiber | RS-FEC Disabled | RS-FEC Enabled |
|---|

Server-to-Switch Connectivity
Modern servers equipped with 25GbE SFP28 network adapters can use the SFP-25G-SR for high-speed optical connectivity to compatible 25GbE network switches.
For a complete optical link, both endpoints must support compatible 25GbE optics, fiber and configuration requirements.
High-Density Networking
The compact SFP28 form factor allows network equipment manufacturers to provide a high number of 25GbE ports within a relatively small physical footprint.
This makes SFP-25G-SR modules useful for high-density data-center environments where rack space and port density are important considerations.
