Abstract
In order to transmit wire and wireless signals simultaneously, a hybrid network was constructed with both the signals transmitted in the two orthogonal pelarization 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 50kin in optical fiber. The results show that this method is very effective in transmission.关键词
