We demonstrate radio-over-fiber (RoF) transmission with a 10-W feed power-over-fiber (PWoF) using a conventional multimode fiber (MMF). In this scheme, the modal dispersion and feed light crosstalk in the MMF are effectively mitigated by the combination of center-launching (CL) and offset-launching (OL) techniques. The CL is used for propagating the feed light into lower-order modes in the MMF, while the OL is used not only for propagating the optical data signals into higher-order modes in the MMF, but also for mitigating the modal dispersion. We successfully achieved significant improvement in the RoF transmission performance with the 10-W feed PWoF and extended the link length up to 4 km, owing to the two techniques.

使用常规多模光纤的基于中心发射和偏移发射技术的光导纤维无线系统

我们演示了使用常规多模光纤（MMF）的10W馈电光纤功率（PWoF）进行的光纤无线电（RoF）传输。在此方案中，通过结合中心发射（CL）和偏移发射（OL）技术，可以有效地缓解MMF中的模态色散和馈电串扰。CL用于在MMF中将馈送光传播到低阶模式，而OL不仅用于在MMF中将光学数据信号传播到高阶模式，还用于减轻模式色散。借助这两种技术，我们成功地通过10 W馈电PWoF实现了RoF传输性能的显着改善，并将链路长度扩展到了4 km。
