摘要

模拟光纤无线电（A-RoF）传输具有超低延迟、频谱效率高、与接收端模拟接口高度兼容等显著优点。然而，由于A-RoF传输的是模拟信号，在传输过程中，信号质量容易下降，难以延长传输距离和保持较高的信号质量。为了解决这个问题，我们提出了一种提高传输质量的方法，即在光传输网络中有意使用非色散补偿的单模光纤。传输实验表明，实现了380公里的传输距离，比世界上最长的宽带a - rof传输距离高出60公里。我们还澄清了传输距离的改善是由于光调制指数的增加。

CNR Improvement Method for 380-km Ultra-Long-Distance A-RoF Transmission Using FM Conversion

Analog radio-over-fiber (A-RoF) transmission has significant advantages such as ultra-low latency, high spectral efficiency, and high compatibility with the analog interface on the receiving side. However, since A-RoF transmits analog signals, the quality is easily degraded during the transmission process, making it difficult to extend the transmission distance and maintain high signal quality. To address this issue, we propose a method to improve the transmission quality by intentionally using non-dispersion-compensated single-mode fibers for the optical transmission network. Transmission experiments clarified that a transmission distance of 380 km was achieved, exceeding the world’s longest broadband A-RoF transmission by 60 km. We also clarified that the improvement in transmission distance is due to an increase in the Optical Modulation Index.
