Embodiment Construction
[0047] The invention provides a full-duplex access method, which is used to realize the wired / wireless selective access of the base station, complete the transmission of the wired / wireless fusion optical signal based on the orthogonal polarization state between the central station and the base station, and increase the number of base stations The flexibility of the access method and the utilization rate of the spectrum reduce the cost. In order to achieve the above effects, the following steps need to be taken:
[0048] First, in the downlink transmitter: if figure 1 As shown, at the central station, the angular frequency is ω 0 =2πf 0 The narrow-linewidth laser emits light waves into a push-pull two-electrode lithium niobate Mach-Zehnder modulator (LiNbO 3 Mach-Zehnder modulator, LN-MZM), where the laser frequency f 0 =193.1THz (1552.5nm), the line width is 50kHz as an example. LN-MZM is located at the maximum transmission point through DC bias, the bias voltage is 0V, an...
