Ilizwe lokuqala (O1)
II-ONUkweli lizwe sele linikwe amandla kwaye lisekho kwi-LOS / LOF. Emva kokuba umlambo osezantsi ufunyenwe, i-LOS kunye ne-LOF zisusa, kunye neI-ONUihambela kwindawo yokulinda (O2).
Ilizwe elilindileyo (O2)
II-ONUkweli lizwe lifunyenwe kwi-flow ezantsi kwaye ilinde iparameters zenethiwekhi ukuba zamkelwe. Xa iI-ONUifumana umyalezo oPhezulu_Ophezulu, qwalasela iI-ONUngokusekelwe kwezi parameters womnatha (umzekelo, delimiters, imo yamandla, preset ukulinganisa ulibaziseko) kwaye idluliselwe kwi-serial inombolo state (O3).
Uthotho-Inombolo-imeko (O3)
IOLTithumela imiyalezo yeSicelo-Inombolo kubo bonkeIi-ONUkweso simo ukufumana entshaIi-ONUkunye neenombolo zabo zeSerial. Xa iOLTufumanisa entshaI-ONU, iI-ONUilindele iOLTukuyabela iI-ONU-ID. IOLTyabela i-ONU-ID ngomyalezo we-Asign_ONU-ID.I-ONUukudluliselwa kwilizwe elisusela (O4) emva kokufumana i-ONU-ID.
I-Ranging-state (O4)
Iisignali ezigqithisiweyo ukusuka ezahlukeneyoIi-ONUkufuneka zingqanyaniswe xa zifika kwiOLT, apho nganyeI-ONUidinga ukulibaziseka kokulinganisa, okulinganiswa kwimeko yokusukela. II-ONUifumana iRangi_Time umyalezo kwaye ihambe iye kwimeko yokusebenza (O5).
I-Operation-state (O5)
Onuskule meko ingathumela idatha kunye nemiyalezo ye-PLOAM phantsi kolawulo lweOLT, kwayeIi-ONUkule meko inokuseka nolunye unxibelelwano njengoko lufuneka. Xa uluhlu luphumelele, zonkeIi-ONUthumela imiqondiso ngokulibaziseka kwabo okulinganayo ukugcina ulungelelwaniso lwesakhelo se-uplink. Iimpawu ezithunyelwa ngokwahlukeneyoIi-ONUiza kufika kwiOLTngokwahlukeneyo, kodwa uphawu ngalunye luzakuvela kanye apho lufanele ukuvela khona kwisakhelo se-uplink. Misa iI-ONUisebenza: Ngexesha lokusebenza okuqhelekileyo, iOLTinokunqumamisa iI-ONUukuthumela imiqondiso ukufumana inombolo yolandelelwano yezinyeIi-ONUokanye ukulinganisa umgama womnyeIi-ONU. IOLTuyayeka ukugunyazisa yonke uplink bandwidth ixesha elithile, kunyeI-ONUisebenza ngendlela eqhelekileyo. Ekubeni akukho sigunyaziso sifunyenweyo, akukho mqondiso uya kuhanjiswa, okubangela ukuba kubekho ixesha elizolileyo, ukuze iOLTyenza konkeIi-ONUnqumamisa imiqondiso yokuhambisa.
I-POPU-state (O6)
II-ONUkwimeko yokusebenza (O5) ingena kweli lizwe xa ibona i-LOS okanye i-LOF. Kule meko, iI-ONUngoko nangoko uyeke ukuthumela imiqondiso, ukuze iOLTizakubona i-alam ye-LOS yale ntoI-ONU. Xa i-ODN fiber iphazamisekile, ezininziIi-ONUizakungena kwesi simo. Ngenxa yokuthembeka kwenethiwekhi, enye yezi ndlela zilandelayo kufuneka isetyenziswe:
Ukuba utshintsho lokugada luvuliwe, zonkeIi-ONUintandotshintshangaphaya kwifiber yokulinda. Ngeli xesha, bonkeIi-ONUiya kuqhuba ukusuka kwakhona, apho iOLTithumela umyalezo wePOPUP yoSasazo ukwazisa zonke ii-ONU ukuba zingenise imeko eyahluka-hlukeneyo (O4).
Ukuba akukho ukutshintshwa kokukhusela kodwaI-ONUinamandla okhuseleko lwangaphakathi, iOLTithumela umyalezo oLathisiweyo we POPUP ukwazisa iI-ONUukungena kwimeko yokusebenza (O5). Xa iI-ONUingena kwimo ye-O5, iOLTkufuneka ukubona iI-ONUkuqala kwaye emva koko
Buyisela inkonzo ye ONU. Ukuba iI-ONUayibuyiseli kwi-LOS okanye i-LOF, iI-ONUayizukufumana umyalezo woSasazo lwePOPUP okanye umyalezo oKhokelwe kwi-POPUP, kunye neI-ONUingena kwimeko yokuqala (O1) emva kwexesha le-TO2.
Emergency-Stop-state (O7)
Xa iI-ONUifumana i Disable_Serial_Nombolo umyalezo ngo "Khubaza" ukhetho, iI-ONUingena kwimeko yokuyeka unxunguphalo (O7) kwaye icime i-laser. Kwimeko O7, iI-ONUakuvumelekanga ukuhambisa imiqondiso. Ukuba iI-ONUayingeni ngempumelelo i-O7 karhulumente kunye neOLTusenako ukuqhubeka ukufumana uphawu oluthunyelwe yiI-ONU, iOLTiyakwenza i-alam ye-Dfi. Xa impazamo yeI-ONUisonjululwe, iOLTithumela i Disable_Serial_Nombolo umyalezo ngo "Vumela" ukhetho lokuvula okoI-ONU. Emva kokufumana umyalezo, iI-ONUingena kwimo yokulinda (O2), kwaye zonke iiparameters (kubandakanya inombolo yolandelelwano kunye ne-ONU-ID) ziya kutshekishwa kwakhona.
Ezi ngongoma zingentla zolwazi zimalunga nenkqubo yenkcazo yeI-ONUubume kunye nokusebenza okuziswe yi-Shenzhen HDV Phoelectron Technology LTD., engumvelisi okhethekileyo kwizixhobo zonxibelelwano njengeemveliso zayo eziphambili. Izixhobo ezinxulumeneyo zibandakanya: OLTI-ONU/ IntelligentONU/ ACI-ONU/ IfayibhaI-ONU/ CATVI-ONU/ GPONI-ONU/XPONONU/OLTizixhobo/OLTTshintsha/GPONOLT/ EPONOLTnjalo njalo, wamkelekile abasebenzisi ukuba beze kuboniswano lwemveliso.
