Abstract
Methods and systems for distribution of digital data services, radio frequency (RF) communications services, and power are provided for use in optical fiber-based distributed communications systems. Electrical digital data signals are received at a distribution unit. Downlink digital data signals representing the electrical digital data signals are distributed from the distribution unit over a downlink digital data services line to a remote antenna unit (RAU). Uplink digital data signals are received from the RAU over an uplink digital data services line and are distributed to head-end equipment. The distribution unit also receives optical RF communications signals and distributes the optical RF communications signals over at least one RF communications services optical fiber to the RAU. Power is also distributed, from at least one power output of the distribution unit, over at least one power line to the RAU.
