What optical module does Huawei AAU use

Huawei AAUs use SFP/SFP+ optical modules to connect to the baseband unit (BBU) via fiber, supporting data rates up to 9.8 Gbit/s per port.OverviewHuawei Active Antenna Units (AAUs) integrate the antenna and radio frequency (RF) units into a single outdoor enclosure, often including Massive MIMO and beamforming capabilities . To connect the AAU to the baseband or central unit, fiber optic links are used, and these require compatible optical modules inserted into the AAU's optical ports .Optical Module SpecificationsForm Factor: SFP (Small Form-factor Pluggable) or SFP+ modules are typically used in Huawei AAUs .Data Rate: Each optical port supports a maximum data rate of 9.8 Gbit/s, suitable for CPRI or eCPRI fronthaul connections .Port Configuration: AAUs generally have two optical ports (Port 0 and Port 1), each requiring an optical module for fiber connectivity .Compatibility: The optical module must match the port's data rate and the required transmission distance. Huawei provides guidance on selecting modules based on CPRI optical fiber configurations and deployment scenarios .Labeling: Each module is labeled with its rate, wavelength, and transmission mode, which ensures proper installation and interoperability .Examples of AAUs and Optical ModulesAAU3902: Uses optical modules to transmit signals between the AAU and fiber optic cables, supporting standard CPRI/eCPRI interfaces .AAU5835f: Integrates the active module and passive antenna, with optical modules connecting the radio unit to the fronthaul network .AAU5942: Features optical ports with SFP modules for BBU connectivity, supporting up to 9.8 Gbit/s per port .Practical ConsiderationsWhen deploying or maintaining Huawei AAUs:Ensure module compatibility with the AAU port data rate and distance requirements.Use manufacturer-approved SFP/SFP+ modules to maintain network performance and reliability.Check the AAU nameplate for the exact module type and part number, as this varies by AAU model . In summary, Huawei AAUs rely on SFP or SFP+ optical modules for fiber connectivity, supporting high-speed fronthaul links and ensuring seamless integration with the baseband network.
