Huawei QSFP-100G-CWDM4 100Gbps 2KM Optical Transceiver Module

The Huawei QSFP-100G-CWDM4 is a 100Gbps QSFP28 optical transceiver designed for high-speed Ethernet connectivity over single-mode fiber. It supports 100GBASE-CWDM4 applications with a transmission distance of up to 2km on G.652 single-mode fiber.

The module uses four CWDM optical wavelengths at 1271nm, 1291nm, 1311nm, and 1331nm and provides a duplex LC optical interface. Its compact QSFP28 form factor makes it suitable for high-density 100Gbps networking applications. :contentReference[oaicite:0]{index=0}

Huawei QSFP-100G-CWDM4 100G Connectivity

The QSFP-100G-CWDM4 is designed for 100Gbps Ethernet connectivity using CWDM technology. Four optical channels, each carrying 25Gbps, are multiplexed across the fiber link to provide the required aggregate 100Gbps bandwidth.

This architecture provides an efficient solution for data center, enterprise, and network aggregation environments requiring more reach than short-range multimode 100G modules while maintaining a compact QSFP28 form factor.

2KM Single-Mode Fiber Transmission

The module is designed for G.652 single-mode fiber (SMF) and supports a target transmission distance of up to 2km. This makes it suitable for interconnecting compatible 100Gbps network equipment across longer data center and enterprise network paths. :contentReference[oaicite:1]{index=1}

Four-Wavelength CWDM Architecture

The optical interface uses four CWDM wavelengths: 1271nm, 1291nm, 1311nm, and 1331nm. These channels operate together to provide 100Gbps optical transmission over the single-mode fiber connection. :contentReference[oaicite:2]{index=2}

QSFP28 and Duplex LC Interface

The QSFP28 form factor provides a compact, hot-pluggable interface for compatible 100Gbps networking equipment. The module uses a duplex LC connector for transmit and receive connectivity over single-mode fiber. :contentReference[oaicite:3]{index=3}
