住宅和商业客户中的宽带渗透和互联网流量的持续增长正在推动当今最终用户的网络接入从电缆迁移到光纤和超宽带无线系统。在下一代光接入网络中，Range被认为是用于增加现有容量和移动性以及降低成本的最有希望的解决方案之一。本文综述了实现超高吞吐量光纤无线网络的几种关键技术，包括基于外部调制或非线性效应的光子毫米波产生技术、频谱高效的多载波正交频分复用技术和单载波多级信号调制技术。我们还展示了一些应用程序中的无线光纤试验使用这些使能技术。结果表明，集成系统是实用的解决方案，提供非常高的吞吐量的无线终端用户在光使能的无线接入网络。
The broadband penetration and continuing growth of Internet traffic among residential and business customers are driving the migration of today's end user's network access from cable to optical fiber and superbroadband wireless systems The integration of optical and wireless systems operating at much higher carrier frequencies in the millimeter-wave (mm-wave) range is considered to be one of the most promising solutions for increasing the existing capacity and mobility, as well as decreasing the costs in next-generation optical access networks. In this paper, several key enabling technologies for very high throughput wireless-over-fiber networks are reviewed, including photonic mm-wave generation based on external modulation or nonlinear effects, spectrum-efficient multicarrier orthogonal frequency-division multiplexing and single-carrier multilevel signal modulation. We also demonstrated some applications in wireless-over-fiber trials using these enabling techniques. The results show that the integrated systems are practical solutions to offer very high throughput wireless to end users in optically enabled wireless access networks.
