FIG. 6 is a schematic diagram of an exemplary RAU 14 configured with power-consuming components. The RAU 14 is configured to receive power over a power line 150 routed to the RAU 14 from either a local power source or a remote power source to make power available for power-consuming components associated with the RAU 14. As a non-limiting example, the power line 150 may provide a voltage of between forty-eight (48) and sixty (60) Volts at a power rating of between eighty (80) to one hundred (100) Watts. In this example, the RAU 14 includes an RF communications module 152 for providing RF communications services. The RF communications module 152 requires power to operate in this embodiment and receives power from the power line 150. Power may be routed from the power line 150 directly to the RF communications module 152, or indirectly from another module. The RF communications module 152 may include any of the previously referenced components to provide RF communications services, including O/E and E/O conversion.
