Providing digital data services as electrical signals and radio-frequency (RF) communications over optical fiber in distributed communications systems, and related components and methods
First Claim
1. A method of operating a wireless communication system located in a building infrastructure, the method comprising:
- distributing power in the wireless communication system using a power unit located in at least one remote unit, distributing power comprising;
conveying digital data signals and power signals through a plurality of electrical input links comprised in an electrical input medium;
distributing the digital data signals to at least one communications interface through at least one electrical communications output comprising a plurality of electrical output links comprising an upper set of electrical output links and a lower set of electrical output links;
distributing the power signals to at least one power interface through at least one electrical power output comprising the lower set of electrical output links;
receiving the digital data signals from the plurality of electrical input links comprised in the electrical input medium;
receiving the power signals from one or more electrical input links of the plurality of electrical input links comprised in the electrical input medium;
providing the received digital data signals from the plurality of electrical input links to the at least one electrical communications output; and
providing the received power signals from the one or more electrical input links exclusively to the lower set of electrical output links of the at least one electrical power output; and
distributing optical radio frequency (RF) communications signals to the at least one remote unit.

Abstract
Distributed communications systems providing and supporting radio frequency (RF) communication services and digital data services, and related components and methods are disclosed. The RF communication services can be distributed over optical fiber to client devices, such as remote units for example. Power can also be distributed over electrical medium that is provided to distribute digital data services, if desired, to provide power to remote communications devices and/or client devices coupled to the remote communications devices for operation. In this manner, as an example, the same electrical medium used to transport digital data signals in the distributed antenna system can also be employed to provide power to the remote communications devices and/or client devices coupled to the remote communications devices. Power may be injected and switched from two or more power sources over selected electrical medium to distribute power for power-consuming components supporting RF communications services and digital data services.
