How to enable Huawei optical module
Huawei optical modules must be certified for use with Huawei switches to ensure reliable transmission and service stability.
Certification and Compatibility
Huawei requires that only certified optical or copper modules be used with its switches, as non-certified modules may compromise network reliability and stability . Certification for 10GE or lower modules began on July 1, 2013, and for 40GE/100GE modules on January 1, 2016 . Certified modules are labeled with "HUAWEI," and their details can be verified using commands like display elabel, display version, or display transceiver on Huawei switches . For high-speed or AOC cable modules, the Vendor Name may show the original manufacturer, so confirmation with Huawei support is recommended .
Types of Optical Modules
Huawei supports a variety of optical modules to meet different transmission requirements :
- SFP/eSFP: Small form-factor pluggable modules; eSFP supports monitoring of voltage, temperature, and optical power.
- SFP+: Higher-rate SFP modules.
- XFP: 10G modules with LC connectors.
- SFP28: Supports 25GE transmission.
- QSFP+ / QSFP28: Quad small form-factor pluggable modules for 40GE or 100GE.
- CFP: Centum form-factor pluggable modules for high-speed data communication. Modules are hot-swappable and compatible with single-mode or multimode fibers, with fiber selection based on core diameter and transmission distance .
Installation and Configuration
- Check compatibility: Ensure the optical module matches the switch interface and fiber type (single-mode vs multimode) and does not exceed the interface rate .
- Insert module: Wear an anti-static wrist strap and insert the module into the switch port.
- Verify port status: Use commands like
display interface <interface-type> <interface-number>to check link status, port rate, and transceiver type . - Monitor optical power: Execute
display transceiver interface <interface> verboseto check wavelength, received, and transmitted optical power . - Troubleshoot: Perform loopback tests or check for shutdown states if the port is not active .
Best Practices
- Avoid mixing single-mode and multimode fibers or modules.
- Do not use a module with a higher rate than the interface supports.
- Regularly monitor transceiver parameters to detect faults early.
- Contact Huawei technical support for verification of module certification or for high-speed/AOC modules . By following these guidelines, Huawei optical modules can be effectively deployed to ensure stable, high-performance network operation.
