Abstract：Afterthe interuptionof homebroadbandopticalcable，due to thecomplex and changeable situationof the fault site，thereisoftennospareavailableopticalcablecore，andtheivestigationandrepairofopticalcablebreakpointstaksa longtime，whichmakes itdiffcult forthebusinesstorecoverquickly.Therefore，threliabilityandefciencyoftheemergency communication system become the key.This paper combines raditional OLTtechnology with modern emergency communication technologytobuildanew OLTemergencyrescue system.The system is divided into two types，wiredand wireless.The wireless emergencyrescue part not only integrates various network element functions such as PONand 5G CPE，but also establishes a two-layerchannel withBRASthrough the5G wirelessinterfacetoachievehigh-speedandstableuplinkandbackhaulof data greatly reducing the impact of faults and improving user perception.
