40G QSFP+ Optical Transceiver

The QSFP-40G-eSM4 provides a 40G Ethernet interface in a compact QSFP+ form factor. It is designed for high-bandwidth network links where 40G connectivity is required between compatible switches and network devices.

The module supports a 40 Gbit/s transmission rate according to Huawei's official hardware documentation. :contentReference[oaicite:3]{index=3}

1310nm Optical Wavelength

The QSFP-40G-eSM4 operates at a 1310nm center wavelength. This wavelength is used for single-mode fiber transmission over longer distances than typical short-range multimode 40G optics.

The 1310nm architecture makes the module suitable for extended-reach network connections within enterprise, campus and data center environments.

10km Transmission Distance

Huawei specifies a target transmission distance of 10km over single-mode fiber. :contentReference[oaicite:4]{index=4}

The actual achievable distance depends on fiber quality, connector condition, optical power levels, link loss, patching and the complete optical budget of the network.

Single-Mode Fiber Support

The Huawei QSFP-40G-eSM4 is designed for single-mode fiber (SMF). Huawei documentation specifies single-mode fiber as the applicable optical medium for the 10km transmission distance. :contentReference[oaicite:5]{index=5}

When deploying the module, use the appropriate single-mode MPO fiber infrastructure and verify connector polarity and fiber strand configuration.

MPO/APC Connector

The module uses an MPO/APC optical connector configuration. Huawei specifies an 8-strand or 12-strand Type-B female connector arrangement. :contentReference[oaicite:6]{index=6}

Correct MPO polarity and compatible fiber termination are important for establishing the optical link. Always match the transceiver connector and fiber assembly before installation.

40GBASE-eSM4

Huawei identifies the QSFP-40G-eSM4 application standard as 40GBASE-eSM4 (non-standard). :contentReference[oaicite:7]{index=7}

Because eSM4 is a Huawei-specific/non-standard optical implementation, compatibility should be verified when connecting the module to third-party switches or transceivers.

DDM Support

The QSFP-40G-eSM4 supports Digital Diagnostic Monitoring (DDM). DDM can provide optical-module monitoring information through compatible network equipment.

This can assist network administrators in monitoring optical conditions and troubleshooting fiber-link issues.

Optical Performance

These optical characteristics are documented by Huawei for the QSFP-40G-eSM4 02311DTR. :contentReference[oaicite:8]{index=8}

40G to 4×10G Breakout

The QSFP-40G-eSM4 can support a 1-to-4 splitting configuration. Huawei states that the optical module can connect a 40GE port to four 10GE ports using an appropriate 1-to-4 cable. :contentReference[oaicite:9]{index=9}

This makes the module useful when migrating from or integrating 10G network connections with a 40G aggregation or uplink interface.

Enterprise Network Applications

• 40G data center uplinks
• Switch-to-switch connections
• Core-to-aggregation links
• Aggregation-to-access connectivity
• Enterprise backbone networks
• Campus network links
• Data center spine-leaf architectures
• 40G to 4×10G breakout applications

Huawei CloudEngine Compatibility

The QSFP-40G-eSM4 is documented for Huawei networking platforms, including CloudEngine switch families. Huawei's hardware documentation lists part number 02311DTR and provides the module's optical and compatibility characteristics. :contentReference[oaicite:10]{index=10}

Software and hardware support can depend on the switch model and software version. Huawei documentation for some platforms specifies minimum software versions for this optical module, so the exact target switch should be checked before installation.

Operating Temperature

The QSFP-40G-eSM4 has a documented operating temperature range of 0°C to 70°C. :contentReference[oaicite:11]{index=11}

This standard-temperature range makes it appropriate for controlled enterprise data center and networking environments.
