我们已经实验证明了一种新的波长复用方案的上行链路连接在光纤无线电（ROF）系统。光载波抑制调制产生的双模光波通过光交错器进行分离。双模光波之一用2.5Gb/s的基带数据调制。另一光波将用于上行链路数据调制的光载波。在基站中不存在用于上游数据生成的附加激光源。该方法简化了ROF系统的结构，降低了系统的成本
We have experimentally demonstrated a novel wavelength reuse scheme for up-link connection in a radio-over-fiber (ROF) system. The dual-mode lightwave generated by optical carrier suppression modulation is separated by an optical interleaver. One of the dual-mode lightwaves is modulated with a baseband data at 2.5 Gb/s. The other lightwave will be used for the optical carrier for the up-link data modulation. There is no additional laser source for the upstream data generation in the base station. By this method, we simplify the configuration of the ROF system and reduce the cost of the system
