RRU and BBU optical modules - Budowa Silesia Photonics [PDF]
The BBU operates in a temperature-controlled indoor environment with air conditioning maintaining a stable room temperature. In contrast, the RRU is exposed to the unregulated outdoor elements,
3G networks use a large number of distributed base station architectures, and optical fiber is required to connect RRU (radio remote module) and BBU (baseband processing unit).
In 5G networks, interfaces between bbu and rru, such as cpri (Common Public Radio Interface) or ecpri (Enhanced Common Public Radio Interface), are often used with optical modules.
These modules are installed between the BBU and RRU, converting high-speed electrical signals into optical signals for transmission via fiber, and back to electrical signals at the destination.
The Remote Radio Head (RRH) architecture consists of a baseband unit (BBU) and a remote radio unit (RRU). Both the BBU and RRU are connected using fiber
The main functions of the Remote Radio Unit (RRU) include: Communicating with the baseband pool (BBU) through optical fiber, including I/Q data and operation and maintenance
AAU (Active Antenna Unit): Integrates multiple beams to receive signals from the RRU, which have been converted from the BBU. The AAU enhances signal transmission and reception
The Remote Radio Head (RRH) architecture consists of a baseband unit (BBU) and a remote radio unit (RRU). Both the BBU and RRU are connected using fiber optic cables to transport digital data and
The BBU modules shall meet shock and vibration test per EN 60068-2-6 and 60068-2-27 for both nonoperating and operating condition, with the specifications listed below.
The base station can be divided into two modules: the RRU for transmitting signals and the BBU for processing signals. The BBU is small and exquisite, with low power consumption, while the RRU is
CPRI modules are designed exclusively for the fronthaul link between a BBU and an RRU in a wireless base station. Their entire design is optimized for this point-to-point, synchronous
