UNDERSTANDING BBU RRU AND AAU IN TELECOM NETWORKS

Bbu and rru optical modules

Bbu and rru optical modules

The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. Optical modules used in Remote Radio Units (RRUs) for CPRI applications are required to support industrial temperature ranges, primarily because RRUs operate in diverse outdoor environments with extreme temperature variations. This process ensures stable signal transmission over long distances and in complex environments. AAU, RRU, and BBU are key components in a telecom network, particularly in modern wireless communication systems like 4G and 5G. Generally, the BBU and RRU are operated separately, the BBU is placed in the engine room and the RRU is placed on the tower, and the equipment connecting the BBU and RRU are optical.
