Embodiment Construction
[0037] An example of URI application using four-wavelength CWDM is shown in the attached figure 1 . by figure 1 Take RRU1 as an example, the structure diagram after using URI on the RRU side is shown in image 3 . In order to facilitate the comparison between URI and TDM multiplexing methods, an example of interconnection between RRU and BBU based on TDM (CPRI or OBSAI) multiplexing is shown in Figure 4 . In the downlink direction, the BBU side sends the communication data with different RRUs on different optical wavelengths. Different optical wavelengths meet the wavelength series of CWDM. Optical signals of different wavelengths are multiplexed to one optical fiber through the optical multiplexing device MUX;
[0038] The RRU side takes out the signal of a specific wavelength supported by the RRU from the optical fiber through the optical add-drop multiplexing device OADM, while the optical signals of other wavelengths are directly transparently transmitted from the RRU...
