OVERVIEW OF PRISM REMOTE UNITS
FlexWavePRUscontrolRFemissions,interfacewiththeFlexWavePrismHostUnitIIandperformthe
opticaltoelectricalconversionfortransporttotheantennas.ThePRUisanenvironmentally-sealedunit
designedforoutdoorusethathousestheelectronicassembliessuchastheDigital/AnalogRadio
Transceiver(DART)boardandthePowerAmplifier,andsealsoutdirtandmoisture.ThePRUusesfans
locatedonthetopofeachunittocoolitschassis.Theantennacableconnectors,fiberconnectors,ACor
DCpowerconnector,andtheunitstatusindicatorarelocatedonthebottomoftheunit.
APRUsupportsorprovidesthefollowingbasicfunctions:
• 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PRUdigitizesthedesignatedRFspectrumanddigitallytransportsitoversinglemodefiberor
MillimeterWave(MMW)totheHost.
• ProvidesRFinterface(antennaport)fortheantennas.
• AcceptseitherACorDCpowerinput.
