摘要

摘要波分复用自由空间光学无线电（WDM RoFSO）系统是提供更远距离从而实现高效 "最后一英里 "连接的最佳选择。但传统的设计无法在恶劣的气候条件下将信息传输到更远的距离。本文提出并仿真了一种改进的 16 信道波分复用-RoFSO 系统，该系统在雾天和雨天的衰减分别为 5.8 dB/km、7.7 dB/km、9.2 dB/km 和 26 dB/km 的情况下，仍能提供高质量的远距离传输。在光信号载体上调制 60 GHz 的射频（RF）信号，并在多雾环境中以 16 × 10 Gbps 的累积比特率成功传输到 3.75 km。在轻雾、中雾、中雨和大雨条件下，链路距离分别增加了 1.65 千米、0.9 千米、1.8 千米和 1 千米。

Range augmentation of 16 × 60 GHz WDM RoFSO system in foggy & rainy weather

Abstract The wavelength division multiplexed radio over free space optics (WDM RoFSO) system is a paramount candidate to provide extended range thus enabling efficient last mile connectivity. But the conventional design is unable to transmit the information up to larger distances under harsh climate conditions. An improved 16 channel WDM-RoFSO system is proposed and simulated which yields quality transmission for extended range under the attenuation of 5.8 dB/km, 7.7 dB/km, 9.2 dB/km and 26 dB/km for foggy and rainy conditions respectively. A radio frequency (RF) signal of 60 GHz is modulated over an optical signal carrier and successfully transported with cumulative 16 × 10 Gbps bit rate up to 3.75 km in foggy environment. The link range is augmented by 1.65 km, 0.9 km, 1.8 km & 1 km for light fog, moderate fog, moderate rainfall and heavy rainfall conditions respectively.
