PRISM REMOTE UNITS
The Prism Remote Unit (PRU), shown in Figure 8, controls RF emissions, interfaces
with the FlexWave Host and performs the optical to electrical conversions for
transport to the antennas. The PRU is an IP-65 rated enclosure that houses the
electronic assemblies such as the RF Module Group, SeRF assembly and AC/DC
power supplies, and seals out dirt and moisture. The PRU uses fans located on the
top of each unit to cool the chassis. The antenna cable connectors, fiber
connectors, AC power connector, and the unit status indicator are located on the
bottom of the unit.

The FlexWave Remote receives on the forward path the digitized spectrum from
the Host and converts the spectrum back into an RF signal to be distributed via an
externally mounted antenna system. On the reverse path, the Remote digitizes
the designated RF spectrum and digitally transports it over single-mode fiber or
Millimeter Wave (MMW) to the Host. The PRU also provides RF interface (antenna
port) for the antennas, and accepts AC power input.
