25Gbps High-Speed Connectivity
The SFP-25G-LR provides 25Gbps optical connectivity for modern high-speed Ethernet networks. Its 25GBASE-LR interface is designed for applications where higher bandwidth is required than traditional 10Gbps Ethernet connections.
The SFP28 form factor provides a compact optical interface suitable for high-density switches, routers and other compatible network equipment.
10km Long-Range Transmission
The Huawei SFP-25G-LR is designed for transmission distances of up to 10km over compatible single-mode fiber. Huawei specifies a G.652 single-mode fiber with a 9μm diameter for the 10km target transmission distance. :contentReference[oaicite:3]{index=3}
Actual achievable distance depends on fiber attenuation, connector loss, splice loss, optical power levels and the characteristics of the complete fiber link.
1310nm Optical Wavelength
The SFP-25G-LR operates at a 1310nm optical wavelength, a wavelength commonly used for long-distance single-mode fiber Ethernet transmission.
The 1310nm wavelength allows the module to operate over single-mode fiber for substantially longer distances than short-range multimode 25G optics.
Single-Mode Fiber Support
The SFP-25G-LR is designed for Single-Mode Fiber (SMF). Huawei specifies G.652 single-mode fiber for the module's 10km target transmission distance. :contentReference[oaicite:4]{index=4}
For reliable operation, use compatible single-mode fiber cabling and appropriate LC optical connectors.
LC Connector
The module uses an LC/DLC optical connector. Huawei's official specification identifies LC/DLC as the connector type. :contentReference[oaicite:5]{index=5}
A duplex LC fiber connection is typically used to provide separate transmit and receive paths between two optical transceivers.
25GBASE-LR Standard
The SFP-25G-LR follows the 25GBASE-LR application standard. This identifies the module as a long-range 25Gbps Ethernet optical solution designed for single-mode fiber.
It is therefore different from 25GBASE-SR modules, which are intended for shorter-distance multimode fiber connections.
Digital Diagnostic Monitoring
Huawei specifies Digital Diagnostic Monitoring (DDM) support for the SFP-25G-LR. :contentReference[oaicite:6]{index=6}
DDM can provide monitoring information such as optical parameters and module operating conditions when supported by the host networking equipment.
Optical Performance
Huawei's official specifications list maximum average transmit optical power of 2dBm and minimum average transmit optical power of -7dBm. The specified optical characteristics should be considered when designing a 10km fiber link. :contentReference[oaicite:7]{index=7}
Actual link performance depends on the optical budget, fiber characteristics, connector losses, splice losses and the optical transceiver installed at the opposite end.
Operating Temperature
The Huawei product page specifies a working case temperature range of -45°C to +85°C for the SFP-25G-LR. :contentReference[oaicite:8]{index=8}
This wide temperature range makes the documented module suitable for demanding networking environments where extended operating-temperature capability is required.
Data Center Applications
The SFP-25G-LR can be used to build high-speed fiber connections between compatible switches, routers and other 25G networking devices.
- Data center interconnects
- Enterprise network uplinks
- 25G server connectivity
- High-speed switch-to-switch links
- Long-distance campus networking
- Network aggregation
- Storage networking
- Telecommunications infrastructure
Enterprise Network Connectivity
25Gbps Ethernet provides increased bandwidth for modern enterprise and data center infrastructure. The Huawei SFP-25G-LR can help connect compatible network equipment over single-mode fiber where a 10km reach is required.
It is particularly useful when network equipment is separated by distances beyond the practical reach of short-range multimode optics.

Compatibility Considerations
The SFP-25G-LR should be installed only in networking equipment that supports compatible SFP28 25G optical modules and the relevant Huawei optical-module configuration.
- Compatible SFP28 port
- 25Gbps Ethernet support
- 25GBASE-LR support
- Single-mode fiber infrastructure
- LC-compatible fiber connectors
- Compatible Huawei firmware and optical-module support
Always verify the exact switch, router or network-device model and supported transceiver list before deployment.
Fiber Link Planning
Although the SFP-25G-LR has a 10km target transmission distance, the actual fiber span should be designed according to the complete optical link budget.
Fiber attenuation, connector insertion loss, splice loss, patch-panel loss and environmental conditions can reduce the usable link distance. For mission-critical deployments, calculate the complete end-to-end optical budget before installation.
