Huawei devices use Huijue optical modules
Huawei devices primarily use Huawei-branded optical modules, such as the StarryLink series, and there is no official confirmation that Huijue optical modules are used.Huawei Optical ModulesHuawei provides a wide range of optical modules for networking and AI computing scenarios, covering speeds from GE to 800GE. These modules are designed to deliver a "3S" network experience: Spanning (ultra-long transmission), Stable (high reliability), and Secure (enhanced security), ensuring resilient data center interconnectivity and high-speed connections for AI workloads . The StarryLink optical module series, launched globally in 2025, is Huawei's flagship brand for high-performance optical interconnects, compatible with various NICs and switches .Compatibility ConsiderationsHuawei devices, including switches like the S5700/S5720 series, require optical modules that match the interface type, transmission rate, and fiber type. Using incompatible modules can result in connection failures or reduced performance. Huawei provides detailed guidance for module selection, emphasizing that single-mode and multi-mode fibers and modules should not be mixed, and that the module's data rate must match the port's capability .Third-Party ModulesWhile some third-party optical modules may physically fit Huawei devices, Huawei does not officially list Huijue optical modules as supported. Using non-Huawei modules may work in some cases but can lead to limited diagnostics, reduced reliability, or unsupported operation. Huawei's own modules, such as StarryLink, undergo rigorous quality control and end-to-end R&D to ensure long-term stability and optimal performance in large-scale AI clusters .ConclusionHuawei devices are designed to work best with Huawei-branded optical modules, particularly the StarryLink series, which are optimized for high-speed, reliable, and secure data center interconnects. There is no official information confirming the use of Huijue optical modules in Huawei equipment, and using third-party modules may carry compatibility and reliability risks .
