Embodiment Construction
[0037] The invention provides a wired and wireless fusion optical fiber asymmetric full-duplex access method, which is used for the central station to generate a fusion optical signal based on orthogonal polarization, to complete the wired and wireless selective access mode of the base station, and the uplink carrier is controlled by the downlink Directly extracting the base station to realize the passivity of the base station, the downlink and the uplink respectively transmit the M-ary vector and the binary data rate to form an asymmetric full-duplex link, rationally allocate spectrum resources, reduce costs, and improve realizability. In order to achieve the above steps, the following steps are required:
[0038] Downlink transmit module: In the central station, the angular frequency is ω 0 =2πf 0 The narrow linewidth laser emits continuous light waves, where the laser frequency f 0 =193.1THz (1552.5nm), line width 10MHz as an example, incident to the polarization beam spl...
