光纤承载射频(ROF,Radio over Fiber)技术是一种先进的通信技术,它能有效的将光和微波技术结合在一起,具有大容量、低成本、易安装等优点。在移动通信中,最基本的要求是得到更丰富的传输带宽、无缝的覆盖范围和低功耗的传输效能。如果将ROF技术与现有网络技术融合起来,可以达到共享昂贵器件、集中控制、降低成本、动态分配网络容量的目的,也可以使移动通信的成本更低,集成化更高。主要介绍ROF技术的特点、ROF的关键技术、着重介绍ROF技术在网络融合中的重要应用。
Optical fiber-bearing radio frequency (ROF) technology is an advanced communication technology that can effectively combine optical and microwave technologies with the advantages of high capacity, low cost and easy installation. In mobile communications, the most basic requirement is to get richer transmission bandwidth, seamless coverage and low-power transmission performance. If you combine ROF technology with existing network technologies, you can achieve the purpose of sharing expensive devices, controlling them centrally, reducing costs, and dynamically allocating network capacity. You can also lower the cost of mobile communications and integrate them more. Mainly introduces the characteristics of ROF technology, ROF key technologies, focusing on ROF technology in network convergence of important applications.
