Problems solved by technology
[0002] At present, when communicating multiple signals (such as baseband signals of 2G, 3G, 4G, 5G, etc.), each signal is transmitted through its own independent device, and it is impossible to realize the coverage of multiple signals by one device
When it is necessary to send multiple types of signals, it is necessary to build a variety of corresponding transmission equipment, which will result in higher costs and even the problem of idle equipment
In addition, in the existing passive optical network mode of wavelength division multiplexing, in addition to optical cables and optical fiber terminal boxes for optical cables, the main components are multiplexers and demultiplexers for wavelength division multiplexing. Optical networks, such as 25G wavelength division multiplexing passive optical networks, the bandwidth of the same colored light wavelength cannot be allocated for bandwidth, and each optical network unit monopolizes its bandwidth, which cannot flexibly meet the optical requirements of wavelength division multiplexing passive optical networks. Different broadband rate requirements of 5G and other multi-standard mobile communication baseband fronthaul networks in distribution networks
