摘要: 为了实现有线信号和无线信号的同时传输,采用将有线信号和无线信号分别在两个正交的偏振态中构造混合网络的方法,用非对称输入的双臂马赫-曾德尔调制器来产生无线信号中的毫米波;利用相位调制器实现差分相位键控调制格式,以便在上行链路中实现载波重用有线信号,分别将调制后两个正交偏振态信号耦合到同一光波长上经过光纤传输至基站。在基站处将两个正交偏振态的信号分离,携带无线信号光载波经光电检测放大后由天线传输出去,而携带有线信号光载波分为两路,一路经过平衡检测器检测得到有线信号,另外一路应用到上行链路中实现载波重用。通过OPTICSYSTEM软件进行了理论分析和实验验证,得到了10Gbit/s有线信号和60GHz无线信号通过光纤传输50km后的眼图。结果表明,该方案传输效果很好。

Abstract: In order to transmit wire and wireless signals simultaneously,a hybrid network was constructed with both the signals transmitted in the two orthogonal polarization respectively,in which wireless millimeter-wave was generated by a nonsymmetrical input dual Mach-Zehnder modulator in a wireless link,while wire signal was generated with a phase modulator to achieve differential phase-shift key modulation format and realize carrier reuse in uplink,then both the orthogonal polarization signals modulated respectively were coupled into the same optical wavelength and transmitted to the base station through the fiber. Both the orthogonal polarization signals were separated in the base station,the optical carrier modulatedby wireless signal was detected by a photodiode and amplified,then transmitted by the antenna.On the other hand,the optical signal carrying wire signal was divided into two signals,one was injected to the balanced detector to achieve wire signal,and the other was used as optical carrier in uplink.After simulation with OPTICSYSTEM software,the eye diagrams of 10Gbit/s wire signal and 60GHz wireless signal were obtained after transmission 50km in optical fiber.The results show that this method is very effective in transmission.
