Relationship between bburru and optical modules
The transmission carriers connecting BBU and RRU devices are optical modules and optical fibers. A BBU-RRU delay setting method comprises: acquiring a fibre length L BBU-RRU between a BBU and an RRU; acquiring a buffer delay Trru required by the RRU and an air interface advance T a corresponding to the RRU; sending the acquired fibre length, the buffer delay Trru required by the RRU and the. In this article, ETU-LINK will introduce the base station under the communication triangle tower and the application of optical modules in the base station. In 4G network, the optical modules used to connect BBU and RRU are mainly Gigabit to 10 Gigabit optical modules; in 5G network, the optical modules used to connect BBU and RRU are mainly 25G rate. 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.
