我们实验证明了一种新的光纤无线电方案，只使用一个强度调制器就可以同时获得独立的有线和无线信号。40 GHz或60 GHz毫米波(mm波)光载波是通过副载波复用技术产生的，用于承载2.5 Gb/S无线信号，而10 Gb/S有线信号则通过规则的强度调制施加到原始光载波上。具有双业务的信号在20公里单模光纤(SMF-28)上成功传输，功率损失小于1.5分贝。
We experimentally demonstrated a novel radio-over-fiber scheme to simultaneously obtain independent wired and wireless signals by using only a single intensity modulator. The optical 40- or 60-GHz millimeter-wave (mm-wave) carriers are generated by means of subcarrier-multiplexing techniques to carry 2.5-Gb/s wireless signals while 10-Gb/s wired signals are imposed on the original optical carrier via regular intensity modulation. The signals with dual services are successfully transmitted over 20-km single-mode fiber (SMF-28) with less than 1.5-dB power penalty.
