Bukatar abokin ciniki:
In order to meet the rapid growth of data traffic, operators need to continuously increase the number of base stations. In order to avoid the shortcomings brought about by the traditional way of station construction, operators gradually adopt the method of centrally placing multiple BBU/DUs. Through the use of matching passive optical modules on BBU/DU and RRU/AAU, it provides service signals of different wavelengths.
Customer requirements:
Refer to the table below for the general technical indicators of the optical interface of the passive coarse wavelength division multiplexer.
