OPTICALPOWERBUDGET
FusionWidebandusesSC/APCconnectors.Theconnectorlossesassociatedwithmatingtothese
connectorsisaccountedforinthedesignandshouldnotbeincludedaselementsoftheoptical
powerbudget.Thereasonisthatwhentheopticalpowerbudgetisdefined,measurementsare
takenwiththeseconnectorsinplace.
TheFusionWidebandopticalpowerbudgetforbothmulti‐modeandsingle‐modefiber
cableis3.0dB(optic
al).
Themaximumlossthroughthefibercannotexceed3dB(optical).
Themaximumlengthsofthe
fibercableshouldnotexceed500m(1,640ft)formulti‐modeand6km(19,685ft)for
single‐mode.Boththeopticalbudgetandthemaximumcablelengthmustbetakeninto
considerationwhendesigningthesystem.
NOTE: ItiscriticaltosystemperformancethatonlySC/APCfiberconnectorsareusedthroughoutthe
fibernetwork,includingfiberdistributionpanels.
