    • Optical fiber-based distributed communications systems that provide and support both RF communication services and digital data services are disclosed herein. The RF communication services and digital data services can be distributed over optical fiber to client devices, such as remote antenna units for example. In certain embodiments, digital data services can be distributed over optical fiber separate from optical fiber distributing RF communication services. In other embodiments, digital data services can be distributed over common optical fiber with RF communication services. For example, digital data services can be distributed over common optical fiber with RF communication services at different wavelengths through wavelength-division multiplexing (WDM) and/or at different frequencies through frequency-division multiplexing (FDM). Power distributed in the optical fiber-based distributed communications system to provide power to remote antenna units can also be accessed to provide power to digital data service components.
    • 本文公开了提供和支持RF通信服务和数字数据服务的基于光纤的分布式通信系统。 RF通信服务和数字数据服务可以通过光纤分发到客户端设备,例如远程天线单元。 在某些实施例中,数字数据业务可以分布在与分配RF通信服务的光纤分开的光纤上。 在其他实施例中,数字数据服务可以通过具有RF通信服务的普通光纤分布。 例如,数字数据业务可以通过波分复用(WDM)和/或通过频分复用(FDM)在不同频率的RF通信服务以不同波长分布在普通光纤上。 分布在基于光纤的分布式通信系统中的功率为远程天线单元提供电力也可以被访问以向数字数据服务组件提供电力。
