Do Huawei switches require optical films

Huawei switches do not require optical films, but they do require certified optical modules for reliable operation.

Optical Module Requirements

Huawei switches are designed to work with optical or copper modules that are certified by Huawei. Using non-certified modules can lead to transmission issues, inaccurate monitoring, or service instability, and Huawei does not guarantee support for such modules . Certification ensures that the module is compatible with the switch's hardware and software, including monitoring features like voltage, temperature, and optical power levels .

Types of Supported Optical Modules

Huawei S series switches support a variety of optical module types, including:

  • SFP, eSFP, SFP+, SFP28 – small form-factor pluggable modules for different speeds
  • XFP, CFP, QSFP+, QSFP28 – higher-speed modules for 10G, 40G, or 100G connections
  • Connector types – LC (Lucent Connector) and MPO (Multi-fiber Push On) connectors All modules are hot-swappable, meaning they can be inserted or removed without powering down the switch .

Installation and Compatibility

When installing optical modules:

  • Ensure the module matches the fiber type (single-mode or multi-mode) and the interface speed of the port .
  • Insert the module horizontally until it snaps into place; no additional optical films or protective layers are required .
  • Use Huawei-certified modules to guarantee accurate monitoring and stable link performance .

Third-Party Modules

While some third-party modules may physically fit, they may not be fully compatible with Huawei switches. Non-certified modules can cause link flaps, incorrect readings, or service interruptions . For reliable operation, it is recommended to use Huawei-certified optical modules.

Conclusion

Huawei switches do not require optical films, but they must use Huawei-certified optical modules to ensure proper operation, monitoring, and network reliability. Using non-certified modules is not recommended and may lead to performance or compatibility issues .
