1.2 Architecture
The remote access units distribute the wireless and Ethernet services received over the fiber-optic infrastructure from the
Corning® optical network evolution (ONE
™
) solutions headend.
The RAU5x is a service-specific module supporting five SISO services that performs the optical to RF conversion of signals
received from the optical interface unit (OIU) at the headend. Signals are automatically filtered, amplified and distributed via
external antennas. Uplink signals are then converted to optical signals before being transmitted back to the OIU.
