Huawei optical module matching

Huawei switches require specific optical modules based on port type, speed, and fiber type, with both official and compatible third-party options available.

Key Considerations for Matching Optical Modules

Port Speed and Type: Ensure the optical module matches the switch port speed. For example, do not use a 10G SFP+ module on a 1G interface. Huawei switches support various port speeds including 100M, 1G, 10G, 25G, 40G, and 100G.

Fiber Type Compatibility: Single-mode (SM) and multi-mode (MM) fibers require corresponding optical modules.

Mixing SM and M

M modules or fibers can prevent link establishment. Wavelength and Distance: Optical modules are designed for specific wavelengths and transmission distances. For instance, LR modules typically support 10 km, ER modules 40 km, and ZR modules 80 km.

Switch Series Examples: S5700/S5720 Series: Use SFP or SFP+ modules depending on port speed. Ensure fiber type and module rate match the interface. CE8800 Series: Supports 25G SFP28, 40G QSFP+, and 100G QSFP28 modules.

Compatible third-party modules from ETU-Link are available for cost-effective deployment. S6700 Series: Compatible with Moduletek SFP-10G-LR and other transceivers, with commands available to check port and transceiver status.

Third-

Party Compatible Modules: Vendors like ETU-Link, Moduletek, and EDGE Optical Solutions provide modules compatible with Huawei switches, including SFP, SFP+, QSFP28, CWDM, DWDM, and bidirectional options. These can reduce costs while maintaining performance and reliability. Verification and Troubleshooting: Use Huawei CLI commands to check port and transceiver status: display interface or display transceiver interface verbose.

Ensure the port is not administratively down and optical power levels are within normal range. Perform loopback tests if connectivity issues arise.

Summary

To match optical modules with Huawei switches effectively: verify port speed, fiber type, wavelength, and distance requirements, and consider using official or certified third-party modules for cost efficiency. Always check module status and compatibility using Huawei CLI commands to ensure proper operation and avoid link failures.
