Far‐EndFault
Far‐EndFaultisavaluablefeatureusedinamediaconverterwhenitlosesReceiveFiberlink,butstillhasavalid
FiberTransmitlink.
Whenafaultoccursonanincomingfiberlink(1),themediaconvertertransmitsa Far‐EndFaultsignalonthe
outgoingfiberlink(2).
Inaddition,theFar‐EndFaultsignalalsoactivatestheLinkPass‐Through,whichinturn
disablesthelinkonthecopperportionofthenetwork(3)and(4).
