Cable Routing/Antenna Selection
Ensureallcables,e.g.powercable,fiber‐opticcable,Antennacablesareroutedandsecuredinaccordancewith
local/nationalrequirementswhileavoidingdamagetothecables.
Antennasandcoaxcab
lesareselectedaspartoftheDASsystemdesignandmayvarywithlocation,frequency,and
powerlevelrequirements.
Useonlyau
thorizedandapprovedantennas,cablesand/orcouplingdevices.Theuseofunapprovedantennas,
cablesorcouplingdevicescouldcausedamageandmaybeofviolationofFCCregulations.
Eachind
ividualantennausedwiththeDASmustbeinstalledtoprovidetheseparationdistanceasspecifiedinthe
RFexposurerequirements(refertospecificRemoteUnitRFExposurelimitsinthesystemdescriptionsection).
Antenna Installation
TheBirdFiberDASsystemsdonotincluderemoteorheadendantenna.Theremoteendantennamustbeselected
duringsystemdesign,theantennamanufacturer’sdatawillberequiredwhencalculatinglinkbudgets.
Antennain
stallationinstructionsareprovidedbytheantennamanufacturer.
Externaldon
orantennasthataremostcommonlyusedincombinationwithDDRorDDHRemoteUnitfamilyfor
outdoorenvironmentare17dBigainantennas.
Safety and Care for Fibers
Everytimeafiberisdisconnectedandre‐connectedcareshouldbetakentoavoidgettingdustontheconnectoror
inthereceptacle.Cleanwithadryfi bercleaningtoolbeforereconnectingthefiberatalltimes.Asinglespeckof
dustcanseverelyimpactthetransmission.Donottouchth
efiberendswithyourfingers.Thatwillleavegreaseon
theconnectorsandmaycausesevereproblems.
CAUTION
Un
authorizedantennas,cables,and/orcouplingdevicesmaycausenon‐conformitywithnationalorinternational
regulations,couldcausedamage,ornon‐conformingERP/EIRP.
WARNING
Avoidlookingintoconnectedfibersandreceptacles.
