H3C optical module compatibility settings

H3C devices support a wide range of optical transceivers, and proper compatibility requires selecting supported modules and configuring interfaces correctly.

Supported Optical Modules

H3C devices are compatible with various optical transceivers, including SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, CFP, CFP2, CXP, and QSFP-DD. These modules handle optical-to-electrical and electrical-to-optical conversions and provide functions such as optical power control, signal probing, IV conversion, and TX-disable. Supported data rates range from 155 Mbps to 400 Gbps, and modules are available for both short- and long-range transmission .

Connector Types

H3C transceivers use the following connector types:

• SC (Subscriber Connector)
• LC (Lucent Connector)
• MPO (Multi-fiber Push On), which are female-only and available in 12, 16, or 24 fibers. MPO connectors can have PC (Physical Contact) or APC (Angle-polished Contact) polish types .

Interface Configuration for Compatibility

To ensure proper operation of optical modules on H3C switches:

1. Check module status using the command: show interface <interface-type> <interface-number> This displays the interface rate, module type, link state, and statistics .
2. Force interface up-mode if the transceiver is not automatically recognized, especially for certain 10G SFP modules like H3C-SFP-10G-T-SO on FlexFabric 5945 switches .
3. Verify supported transceiver models using H3C compatibility matrices or vendor guides. Third-party modules may work if explicitly listed as compatible .
4. MAC and port binding may be required for some configurations, particularly on S5810 series switches, to ensure the port only allows traffic from specific devices .

Third-Party Module Considerations

H3C supports certain third-party optical modules, but it is recommended to:

• Confirm compatibility using official H3C guides or vendor matrices.
• Test modules in a controlled environment before deployment.
• Use modules that match the required data rate, connector type, and transmission distance .

Best Practices

• Always use modules listed in the H3C compatibility matrix.
• Monitor link state and error statistics after installation.
• Avoid unsupported RJ45 10G transceivers on switches that do not support them.
• For high-speed modules (100G+), ensure the switch firmware supports the specific QSFP or CFP module type. By following these guidelines, H3C optical modules can be deployed reliably, ensuring proper data transmission and network stability.
