Huawei Switch Third-Party Optical Module

Huawei switches can technically use third-party optical modules, but only Huawei-certified modules are guaranteed for reliability and support.

Third-Party Optical Modules Overview

Third-party optical modules are transceivers manufactured by independent vendors rather than the original equipment manufacturer (OEM). They perform the same function as Huawei modules—converting electrical signals to optical signals and vice versa—but are generally lower in cost while following the same technical standards (MSA-compliant) for form factor and interface . High-quality third-party modules are widely used in enterprise and data center networks and are considered safe if sourced from reputable suppliers .

Huawei's Compatibility and Certification Policy

Huawei devices, including the S5735-S series switches, support optical modules that meet the MSA standard, which allows third-party modules to physically fit. However, form-factor compatibility does not guarantee full operational reliability. Huawei explicitly states that only certified modules are guaranteed to work reliably on their switches, and non-certified modules may cause link failures, performance degradation, or service instability . Huawei will not provide technical support for issues caused by non-certified modules . Certification for Huawei optical modules began in 2013 for 10GE and lower-speed modules and in 2016 for 40GE and 100GE modules. Certified modules are labeled with "HUAWEI" and can be verified using commands such as display transceiver on Huawei switches . Non-certified third-party modules may display the original manufacturer's name instead of Huawei.

Practical Considerations

• Cost vs. Risk: Third-party modules can reduce costs significantly, but using non-certified modules carries a risk of reduced reliability and no official support .
• Compatibility Check: To ensure proper operation, it is recommended to confirm module compatibility with Huawei technical support or use modules from suppliers that provide Huawei-certified options .
• Performance: Certified Huawei modules are tested for full functionality, including monitoring of voltage, temperature, bias current, and optical power, which may not be fully supported by generic third-party modules .

Conclusion

Huawei does not prohibit the use of third-party optical modules, but for guaranteed reliability, performance, and support, only Huawei-certified modules should be used. High-quality third-party modules can be a cost-effective alternative if they are certified or verified for compatibility with Huawei equipment .
