Inkqubo ye-PON ithatha itekhnoloji yokwahlula-hlula ixesha kwi-uplink direction, kunye neI-ONUithumela iidatagrams ukuya kwicala le-uplink ngokwesitampu sexesha esabiwe yiOLT. Xa iI-ONUikhupha ukukhanya ngaphandle kokwabela isitampu sexesha, iya kungqubana nemiqondiso yokukhutshwa yenye i-onus, eya kuchaphazela unxibelelwano oluqhelekileyo lwenye i-onus okanye yonke i-onus. Isitampu sexesha sibonisa ukuba umkhohlisiI-ONUayithumeli imiqondiso yokubona phezulu.I-onus ekhohlakeleyo yahlulwe yaba ziindidi ezimbini, enye ikukukhanya okungacwangciswanga kwaye enye kukukhanya okude.Ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo ye-PON kwaye ugweme ukudideka kwinkqubo ngenxa yokuvela kwe-onus ekhohlakeleyo kwinkqubo. IHuawei inomsebenzi wokufumana ii-ONU ezikhohlakeleyo. Lo ngumsebenzi okwinkqubo yePON ejonga iitheminali ezingathumeli ukukhanya ngexesha elililo kwaye emva koko zibe zodwa.
UmkhohlakaliI-ONUumsebenzi wokufumanisa ubandakanya iindlela ezimbini:
1. OLTukubhaqwa
Xa iOLTIbhaqa into ekhupha ixesha elideI-ONU, ithumela umyalelo wokwahlula i ONU ngokwe ONU echongiweyo. Ngokubanzi, iOLTumsebenzi wokufumanisa usetyenziswa kwi-long-emittingI-ONU, kwaye kukho impazamo ethile ekuchongeni ukukhutshwa okungahleliweyoI-ONU.Ngokungagqibekanga, iOLTicima iOLTumsebenzi wokubona. Ngeli xesha, iOLTingabhaqa ukuba kukho u-onus omde okhuphayo kumgca wePON. Nangona kunjalo, inokugweba kuphela ukuba kukho i-onus ekhupha ixesha elide phantsi kwe-PON port, kwaye ayikwazi ukufumana i-onus ethile. Kufuneka ifumane i-onus ekhohlakeleyo ngoqhawulo lwefiber kwisiza.IOLTinokuchonga into ethileI-ONUekhupha ukukhanya phantsi kwezibuko lePON kwaye inokulawula ukude ukucima amandla othumelo lweI-ONUimodyuli yokubona; Umqathango wokuba zonke ii-ONU eziphantsi kojongano lwePON ziyafuneka ukuba zikwazi ukwahlula i-downlink ploam umyalezo kwaye ziphendule ngokuchanekileyo.
2. I-ONUkancinci
Xa iI-ONUIbhaqa ukukhutshwa kokukhanya okude, iya kukwahlula ngokuzenzekelayo. Lo msebenzi unako ukubona iI-ONUkunye nokukhutshwa kokukhanya okude kunye nokukhutshwa kokukhanya okungahleliwe.
3. Unyino lolawulo lothungelwano ekufumaneni i-onus ekhohlakeleyo
Ngokwale migaqo ingentla, ulawulo lwenethiwekhi kufuneka luhlangabezane neemeko ezimbini xa lufumanisa i-onus ekhohlakeleyo. Enye kukuba umsebenzi wokufumanisa uvuliwe, kwaye enye kukuba yonke i-onus phantsi kwe-PON port inokuhlalutya umyalezo we-downlink ploam kwaye uphendule ngokuchanekileyo.
Ngoko ke, ulawulo lwenethiwekhi lunethuba elithile lokufumanisa kunye nokuchonga ulwazi lwezixhobo ze-rogueI-ONUkugebenga ohleli ixesha elideI-ONU, ebavumela ukuba bakhangele iI-ONUindawo ngokudibeneyo nolawulo lwe-asethi; Kwi-onus ekhohlakeleyo ekhupha ukukhanya ngokuqhubekayo, akukho ndlela ilungileyo yokufumana kunye nokubeka indawo ye-onus.
Indlela ephambili yokucubungula i-onus ekhohlakeleyo iseyi-step-by-step-out test kwi-splitter ye-optical splitter, ngoko kubaluleke kakhulu ukuhlaziya ulwazi malunga nokulawulwa kwempahla.
Oku kungasentla yingcaciso yolwazi “yendlela umkhohlakaliI-ONUyabakho” iziswe kuwe yi-Shenzhen HDV photoelectric Technology Co., Ltd. Iimveliso zonxibelelwano eziveliswe yinkampani zigubungela;
