100GBASE-LR4 Optical Technology
100GBASE-LR4 is a long-reach 100GbE optical technology that uses four optical wavelengths to transport 100Gbps traffic over single-mode fiber. Each optical lane carries approximately 25Gbps, while an internal multiplexer combines the four lanes into a single duplex-fiber connection.
The Huawei 34061478 uses LAN-WDM wavelengths centered around 1295nm, 1300nm, 1304nm and 1309nm. Huawei's official documentation specifies these wavelengths and a 10km target distance over G.652 SMF. Huawei official specifications
1295nm–1310nm LAN-WDM
The module is commonly described using a 1295nm to 1310nm wavelength range. Technically, LR4 does not operate at one single wavelength; it uses four separate LAN-WDM channels around the 1310nm optical band.
| Optical Lane | Center Wavelength |
|---|
| Lane 1 | 1295nm |
| Lane 2 | 1300nm |
| Lane 3 | 1304nm |
| Lane 4 | 1309nm |
Huawei's published QSFP28-100G-LR4 specification lists these four center wavelengths. Huawei technical documentation
10km Single-Mode Fiber Reach
The Huawei QSFP-100G-LR4 34061478 is designed for optical links of up to 10km over compatible G.652 single-mode fiber.
This makes it suitable for data center interconnects, enterprise backbone links, campus core networks, metro aggregation and long-distance switch-to-switch connections.
Actual achievable distance depends on fiber attenuation, connector losses, splice losses, patch-panel losses and the complete optical power budget.
Duplex LC Connector
The module uses a duplex LC optical connector. One fiber carries the transmit path and the second fiber carries the receive path.
Duplex LC single-mode fiber is widely deployed in enterprise, telecom and data center environments, making the module suitable for existing 100G LR4 fiber infrastructure.
Optical Performance
Huawei's published QSFP28-100G-LR4 specifications specify a maximum average transmit power of 4.5dBm, minimum average transmit power of -4.3dBm, receiver sensitivity of -8.6dBm and receiver overload power of 4.5dBm. Huawei technical specifications
These values provide the basis for optical link-budget planning. The complete link should account for fiber attenuation, connectors, splices and appropriate system margin.
Digital Diagnostic Monitoring
The Huawei LR4 QSFP28 module supports digital diagnostic functionality. Compatible Huawei equipment can use the module's management interface to retrieve optical and operating information.
Depending on the host platform, diagnostic information can include temperature, voltage, laser bias and optical transmit/receive power.
0°C to 70°C Operating Temperature
The Huawei QSFP28-100G-LR4 is specified for a commercial operating temperature range of 0°C to 70°C. Huawei's documentation lists this operating-case-temperature range for the LR4 module. Huawei official documentation
