8 Power requirements and output power
8.1 RF Module power requirements and output power
DC cable requirements for 60 W RF Modules
48VDCpowercanbefedtotheRFModuledirectlyfromtheSystemModuleorfroman
externalpowersource.Inbothcases,theinternalpowercablewithbootincludedinthe
RFModuledeliverymustbeconnectedtotheRFModuletoprovideIP65protection.

IfthecablepathbetweentheSystemmoduleandRFModuleislessthan2mthen
theinternalpowercableincludedintheRFModuledeliveryisconnecteddirectlyto
theSystemmoduleandRFModule.Theoptional4m(13.1ft)powercableFPTA

IfthecablepathbetweentheSystemModuleandRFModuleexceeds4m(13.1ft),
thenapairofFSEC/FSESs(FlexiSystemExternalOVP)mustbeinstalledbetween
theSystemmoduleandRFModule.Fordetails,seeCreatingFlexiMultiradioBTS

ForallRFModuleswithoronlymoduleswiththe3-terminalDCconnectorif48VDC
powerissuppliedtotheRFmodulefromanexternalpowersource,thenan
FSEC/FSESmustbeinstalledbetweentheexternalpowersourceandtheRF
module.TheinternalpowercableincludedintheRFmoduledeliverymustbe
connectedfromtheRFmoduletotheFSEC/FSES.
DC cable requirements for 80 W RF Modules
TheDCcableisnotincludedinthe80WRFModuledelivery.48VDCpowercanbefed
fromaSystemModuleordirectlyfromanexternalpowersource.
IfthecablepathbetweentheSystemModuleandRFModuleexceeds10m(32.8ft),
thenaFSEC/FSES(FlexiSystemExternalOVP)mustbeinstallednexttotheSystem
moduleorexternalpowersource.Fordetails,seeCreatingFlexiMultiradioBTSSite
