400Gbps High-Speed Connectivity
The QSFP-DD-400G-FR4 delivers a 400Gbps optical transmission rate, providing high-bandwidth connectivity for modern data center and enterprise networking environments.
400G optical interfaces are designed for high-density network architectures where large amounts of traffic must be transported between switches, routers, servers and other network infrastructure.
400GBASE-FR4 Standard
The Huawei QSFP-DD-400G-FR4 uses the 400GBASE-FR4 application standard. Huawei's official documentation identifies this module specifically as a 400GBASE-FR4 optical module. :contentReference[oaicite:3]{index=3}
FR4 uses four optical wavelengths to provide 400Gbps transmission over single-mode fiber. The Huawei module specifies four center wavelengths of 1271nm, 1291nm, 1311nm and 1331nm. :contentReference[oaicite:4]{index=4}
2KM Transmission Distance
The QSFP-DD-400G-FR4 supports a target transmission distance of up to 2km over G.652 single-mode fiber with a 9µm fiber diameter. :contentReference[oaicite:5]{index=5}
This makes the module appropriate for high-speed connections between network devices located within the same data center campus, nearby facilities or other locations within the supported optical reach.
Single-Mode Fiber Support
The module is designed for single-mode fiber (SMF). Huawei specifies G.652 single-mode fiber with a nominal 9µm diameter for the 2km target transmission distance. :contentReference[oaicite:6]{index=6}
Using the appropriate single-mode fiber cabling and compatible optical connectors is important for achieving the specified transmission distance and link performance.
LC/DLC Connector
The QSFP-DD-400G-FR4 uses an LC/DLC optical connector. Huawei's official product documentation identifies LC/DLC as the connector type. :contentReference[oaicite:7]{index=7}
The duplex LC-style interface provides a practical optical connection for structured data center cabling and point-to-point 400G network links.
Four-Wavelength CWDM Architecture
The FR4 optical design uses four wavelengths across the optical link. Huawei specifies center wavelengths of 1271nm, 1291nm, 1311nm and 1331nm. :contentReference[oaicite:8]{index=8}
This wavelength multiplexing approach allows four optical channels to operate together through the duplex fiber interface while providing the aggregate 400Gbps transmission rate.
Digital Diagnostic Monitoring
The Huawei QSFP-DD-400G-FR4 supports Digital Diagnostic Monitoring (DDM). :contentReference[oaicite:9]{index=9}
DDM provides supported network equipment with diagnostic information that can help administrators monitor optical-module operating conditions and troubleshoot network links.
Operating Temperature
The module has a specified operating case-temperature range of 0°C to 70°C. Huawei lists this range for the QSFP-DD-400G-FR4 optical module. :contentReference[oaicite:10]{index=10}
This commercial-temperature operating range is suitable for many controlled data center and enterprise networking environments.
Optical Transmitter and Receiver
Huawei identifies the QSFP-DD-400G-FR4 transmitter as an EML type and the receiver as a PIN type. :contentReference[oaicite:11]{index=11}
The optical specifications include a maximum transmit optical power of 3.5dBm and minimum transmit optical power of -3.3dBm. Huawei specifies receiver sensitivity as max(-4.6, SECQ-6)dBm. :contentReference[oaicite:12]{index=12}
