基于ROF的移动回程/前传中的高级服务数据供应
Advanced service data provisioning in ROF-based mobile backhauls/fronthauls
摘要：
提出并讨论了一种新的具有成本效益的概念，以实现对5G及更高接入网络中的服务质量指标和其他服务数据的实时监控，该概念使用基于处于光注入锁定模式的垂直腔表面发射激光器的单独返回信道，该激光器同时作为光发射器和谐振腔增强型光电探测器操作。通过对射频载波多位置正交幅度调制的高速数字信号进行光学解调的概念验证实验，验证了该方法的可行性和有效性。
英文摘要：
A new cost-efficient concept to realize a real-time monitoring of quality-of-service metrics and other service data in 5G and beyond access network using a separate return channel based on a vertical cavity surface emitting laser in the optical injection locked mode that simultaneously operates as an optical transmitter and as a resonant cavity enhanced photodetector, is proposed and discussed. The feasibility and efficiency of the proposed approach are confirmed by a proof-of-concept experiment when optically transceiving high-speed digital signal with multi-position quadrature amplitude modulation of a radio-frequency carrier.
