H3C optical modules start up automatically when inserted, and their operational status can be verified via CLI commands on the switch.
H3C devices support a variety of optical modules, including transceivers, optical transmitters, receivers, and transponders. Transceivers handle optical-to-electrical and electrical-to-optical conversions and provide functions such as optical power control, signal probing, IV conversion, and decision regeneration. Common form factors include SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, CFP, CFP2, and CXP. Supported data rates range from 100 Mbps to 400 Gbps, and transmission distances are classified as short-range (≤2 km) or long-range (≈10 km) depending on fiber type and module specifications .
When an optical module is inserted into an H3C device:
To check the status of an optical module on an H3C switch:
CodeCopydisplay interface
This command shows interface rate, module type, link state, and statistics. A link state of UP confirms proper startup .
CodeCopydisplay interface brief
This lists all interfaces and their current status, helping identify which ports have active optical modules .
quit, return, or Ctrl+Z to navigate between CLI views when configuring or monitoring modules .By following these steps, H3C optical modules can be successfully started, monitored, and maintained for reliable optical network operation.
To promptly identify or resolve module compatibility issues and improve the adaptability of modules to the device,
