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.
