40GBASE-iSM4 Optical Standard

The Huawei 02311DRW uses the 40GBASE-iSM4 optical standard. Huawei documentation identifies this as a non-standard 40G optical application for the module. :contentReference[oaicite:4]{index=4}

Because iSM4 is a Huawei-specific/non-standard application, compatibility should be verified before using this module with third-party networking equipment.

1310nm Optical Wavelength

The QSFP-40G-iSM4 operates at a nominal 1310nm wavelength. This wavelength is designed for single-mode fiber transmission and supports the module's 1.4km target distance. :contentReference[oaicite:5]{index=5}

Single-Mode Fiber Support

The 02311DRW is designed for single-mode fiber (SMF). Huawei specifies G.652 single-mode fiber with a 9μm fiber diameter and a maximum transmission distance of 1.4km. :contentReference[oaicite:6]{index=6}

The module should therefore be paired with an appropriate single-mode MPO/APC fiber infrastructure for reliable operation.

MPO/APC Connector

The QSFP-40G-iSM4 uses an MPO/APC connector. Huawei documentation specifies an 8-strand or 12-strand, Type B, female connector configuration. :contentReference[oaicite:7]{index=7}

Correct fiber polarity, connector type and fiber count are important when deploying the module. Verify the existing cabling infrastructure before ordering.

1.4km Transmission Distance

The Huawei QSFP-40G-iSM4 supports a maximum transmission distance of 1.4km over compatible G.652 single-mode fiber. :contentReference[oaicite:8]{index=8}

Actual link distance depends on fiber attenuation, connector losses, patch panels, optical budget and overall link quality.

Optical Performance

These optical specifications are documented by Huawei for the QSFP-40G-iSM4 02311DRW. :contentReference[oaicite:9]{index=9}

DDM / DOM Monitoring

The QSFP-40G-iSM4 supports Digital Diagnostic Monitoring (DDM). This capability allows compatible networking equipment to monitor operating parameters of the optical module. :contentReference[oaicite:10]{index=10}

Depending on the host platform, monitored parameters can help network administrators assess optical conditions and troubleshoot link performance.

Operating Temperature

The specified operating temperature range is 0°C to 70°C. This makes the module suitable for standard data center and enterprise networking environments operating within the specified temperature range. :contentReference[oaicite:11]{index=11}

40GE to 4x10GE Breakout

The Huawei QSFP-40G-iSM4 can connect a 40GE port to four 10GE ports using a compatible 1-to-4 breakout cable. Huawei explicitly documents this application for the module. :contentReference[oaicite:12]{index=12}

This makes the module useful when migrating or integrating 40GbE uplinks with multiple 10GbE downstream connections.

Huawei Network Compatibility

Huawei documentation lists the QSFP-40G-iSM4 02311DRW across multiple Huawei networking platforms. The module is documented for Huawei CloudEngine and S-series switch environments. :contentReference[oaicite:13]{index=13}

Huawei documentation also notes that certain platforms require specific software versions. For example, the S12700 documentation states that this module requires V200R009C00 or later on the applicable switch platform. :contentReference[oaicite:14]{index=14}

Always verify the exact switch model, line card and software version before deployment.
