Non-Huawei optical modules

Non-Huawei certified optical modules can function in Huawei switches but may cause operational issues, alarms, and potential hardware damage.

Risks of Using Non-

Certified ModulesNon-Huawei certified optical modules are not fully verified for compatibility and performance on Huawei devices. Potential risks include: Physical incompatibility: Non-standard structure or size may prevent installation on adjacent ports or violate Multi-Source Agreement (MSA) standards, causing mechanical interference with other modules. Data bus defects: Some third-party modules may have design flaws that suspend the switch's data bus, leading to unreadable data and service interruptions.

Electrical damage: Improper edge connector sizes can short-circuit optical interfaces, potentially damaging the switch hardware. Incorrect monitoring and alarms: Temperature or diagnostic readings may be unnormalized, triggering false alarms or misreporting module status.

Identification of Certified Modules

To ensure reliability, Huawei recommends using certified modules. Certified modules can be identified by: Labeling: Certified modules display "HUAWEI" on the label. Command verification: On devices running V600 or later, commands like display interface transceiver or display device elabel can confirm certification by showing Huawei as the vendor and a manufacturing date after July 1, 2013.

Managing Alarms for Third-

Party Modules

Huawei switches authenticate inserted optical modules and generate alarms for non-certified modules. These alarms do not prevent the module from linking up but may clutter logs. To manage this: Use the command transceiver non-certified-alarm disable in system view to suppress alarms while allowing normal operation.

Note that disabling alarms does not mitigate the underlying risks of using non-certified modules, such as potential hardware damage or data bus issues.

Recommendations

Prefer certified modules for critical or high-speed links to ensure reliability and maintain warranty support. If using third-party modules, monitor system performance closely and consider disabling alarms to reduce log noise, but remain aware of potential operational risks. Consult Huawei technical support to verify module certification status or for guidance on safe deployment of non-certified modules.

Using non-Huawei certified optical modules can be a cost-saving option, but it carries significant risks to network stability, hardware integrity, and support eligibility. Proper identification, monitoring, and cautious deployment are essential to minimize potential issues.
