How to insert the optical module for RRU inter-machine connection
Insert one end of the CPRI optical cable into the optical module, and then lead the CPRI optical cable out of the cabinet along the right side of the cabinet. Wrap the fiber tail with the winding pipe. The grounding resistance of the PGND cable should be less than 10 ohms. It also provides checklists as reference. In this document, eRRU3232 is used as an example. 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. The base station can be divided into two modules: RRU for transmitting signals and BBU for processing signals.
