Isithombe 1 siyishadi lokugeleza kwendlela yokuthi i-onu ivumelane nokulingana okungu-10g/10g kanye nokungalingani okungu-10g/1g ekubonakalisweni kwalesi sisungulo.
Izindlela ezinemininingwane
Lo mklamo ozosungulwa uzochazwa ngemininingwane eyengeziwe ngezansi kanye nemidwebo ehambisana nawo kanye nezibonelo.
I-onu ekubunjweni kwalesi sisungulo ivumelana nokulingana okungu-10g/10g kanye nokungalingani okungu-10g/1g, futhi isetshenziswa esimweni se-10gepon.
Ngalesi sisekelo, njengoba kuboniswe kuMfanekiso 1, i-onu ekubonakalisweni kwalesi sisungulo ivumelana nokulingana okungu-10g/10g kanye nokungalingani okungu-10g/1g, okuhlanganisa nezinyathelo ezilandelayo:
s1: Uma i-onu iqala, thola uhlobo lwe-optical module ye-onu. Uma i-optical module iyi-optical module ehambisanayo, kusho ukuthi i-onu yamanje inamandla okusebenza kokubili kwimodi ehambisanayo kanye nemodi engafaniyo. Ngalesi sikhathi, iya ku-s2. Uma i-optical module iyi-optical module engafaniyo isho ukuthi i-onu yamanje inamandla okusebenza kwimodi engafaniyo. Ngalesi sikhathi, i-onu ingazivumelanisa kuphela nemodi ehambisanayo engu-10g/10g, ngakho-ke iphetha ngqo ukunciphisa izindleko zokusebenza nokuthuthukisa ukusebenza kahle komsebenzi.
s2: Uma i-onu ishintsha isuka esimweni sokungabikho kokukhanya iye esimweni sokukhanya, phinda uthole uhlobo lwe-optical module ye-onu. Uma i-optical module iyi-optical module ehambisanayo, iya ku-s3 (isizathu sifana ne-s1). Uma i-optical module iyi-optical module engalingani, bese uphela ngqo (isizathu sifana ne-s1).
Umgomo we-s2 uthi: isizathu sokuthi i-onu ishintshe isuke esimweni sokungakhanyi iye esimweni sokukhanya yilokhu: imoduli ye-optical ku-onu iyashintshwa, ngakho-ke uhlobo lwemoduli ye-optical ludinga ukutholakala futhi ukuqinisekisa ikhono le-onu lokwaziwa ngokunembile. Ngaphezu kwalokho, ngoba kukhona indawo lapho i-onu ivuliwe khona lapho ixhunywe ku-fiber ye-optical, i-onu ibilokhu ithola ukukhanya kwe-downlink okuthunyelwe yi-olt, futhi kungenzeka ingakwazi ukubona umcimbi oshintsha kusuka esimweni sokungakhanyi iye esimweni sokukhanya. Ngakho-ke, ukuze kuqinisekiswe ukuthi i-s2 ingakwazi Kuqashwe ukuthi i-onu ishintsha isuke esimweni sokungakhanyi iye esimweni sokukhanya. Kuyadingeka ukuvala umsebenzi wokwamukela ukukhanya wemoduli ye-optical ngesikhathi senqubo yokuqalisa ye-onu ku-s1, bese uvula umsebenzi wokwamukela ukukhanya wemoduli ye-optical ngemva kokuthi ukuqalisa kwe-onu kuqediwe. Dala umcimbi lapho i-onu ishintsha isuke esimweni esimnyama iye esimweni sokukhanya.
Inqubo yokuthola uhlobo lwe-onu optical module ku-s2 yile: funda irejista ye-optical module nge-i2c (ibhasi elilula, elinocingo oluphindwe kabili elihambisanayo elithuthukiswe yinkampani i-philips) ukuthola ulwazi lohlobo lwe-optical module (uhlamvu lomkhiqizi kanye nezinhlamvu zemodeli). Thola uhlobo lwe-optical module oluhambisanayo ngokuya ngolwazi lohlobo. Inqubo ethile yile: setha kusengaphambili i-optical module database endaweni. I-optical module database ifaka ulwazi lohlobo lwe-optical module kanye nohlobo oluhambisanayo. Uhlobo oluhambisanayo lusetshenziswa njengohlobo lwe-optical module.
s3: Nquma imodi yokusebenza yamanje ye-onu. Uma imodi yokusebenza ye-onu iyimodi elinganayo, kuyadingeka ukunquma ukuthi i-onu kufanele iguqulwe ibe yimodi elinganayo ngokwe-OLT, okungukuthi, iya ku-s4; uma imodi yokusebenza ye-onu iyimodi elinganayo, khona-ke kudingeka ukunquma ukuthi i-onu izoshintshela kwimodi elinganayo ngokwe-olt, okungukuthi iya ku-s5.
s4: Nquma ukuthi inani lezikhathi i-olt ethumela ngazo ulwazi lwewindi kumodi engalingani lingaphezu komkhawulo ochaziwe (izinqumo eziningi zibangelwa ukucatshangelwa kokuqina, izikhathi ezi-5 kulolu hlobo), futhi uma kunjalo, kufakazela ukuthi i-olt ine-uplink 1g kuphela. Amandla, okungukuthi, i-OLT ikwimodi engalingani, ngalesi sikhathi, shintsha imodi yokusebenza ye-ONU kusuka kumodi engalingani iye kumodi engalingani, bese uphela; ngaphandle kwalokho, kufakazela ukuthi i-OLT inamandla e-uplink 10g kuphela (okungukuthi, i-ONU ikhiphe ulwazi lwewindi lwemodi engalingani), Okusho ukuthi, i-olt isekela imodi engalingani. Ngalesi sikhathi, imodi yokusebenza ye-onu iyagcinwa, futhi ukuphela sekuphelile.
s5: Nquma ukuthi inani lolwazi lwewindi oluthunyelwe yi-olt kwimodi yokulinganisa lifinyelele yini emkhawulweni ochaziwe (izikhathi ezi-5 kulolu hlobo). Uma kunjalo, kufakazela ukuthi i-olt inamandla okuxhumanisa i-10g, futhi ishintsha kusuka kwimodi yokungalingani iye kwimodi yokulinganisa. Ngalesi sikhathi, shintsha imodi yokusebenza ye-onu kusuka kwimodi yokungalingani iye kwimodi yokulinganisa, bese uphela; ngaphandle kwalokho, kufakazela ukuthi i-OLT inamandla okuxhumanisa i-1G kuphela, okungukuthi, i-OLT ikwimodi yokungalingani, futhi ngalesi sikhathi, gcina imodi yokusebenza ye-onu, bese uphela.
Ulwazi lwewindi lwemodi engalingani ku-s4 kanye nolwazi lwewindi lwemodi engalingani ku-s5 lutholakala kufreyimu ye-mpcpgate ekhishwe yi-OLT. Ulwazi lwewindi lwemodi engalingani luwulwazi lwewindi le-uplink 1g, kanti ulwazi lwewindi lwemodi engalingani luwulwazi lwewindi le-uplink 10g.
Uma sibheka ku-s1 kuya ku-s2, kungabonakala ukuthi ukwenziwa kwalesi simangaliso kuqala kuthola uhlobo lwe-onu ngokunembile, futhi uma sibheka ku-s3 kuya ku-s5, kungabonakala ukuthi ukwenziwa kwalesi simangaliso kungabona imodi yokusebenza ye-OLT, futhi kuvumelaniswe nokulungisa imodi yokusebenza ye-ONU ngokwemodi yokusebenza ye-OLT, ukuze kutholakale ukwenziwa okuphelele kwe-OLT kanye ne-ONU, futhi ukungafani phakathi kwemodi yokugcina yendawo kanye nemodi yokugcina ekude kubuciko bangaphambilini ngeke kwenzeke.
I-onu ekubunjweni kwalesi sisungulo ivumelana nezinhlelo ezilinganayo ezingu-10g/10g kanye nezingenakulinganiswa ezingu-10g/1g, futhi ibonakala ngokuthi: uhlelo luhlanganisa imoduli yokuthola i-onu, imoduli yokushintsha imodi elinganayo, kanye nemoduli yokushintsha imodi engafani ehlelwe ku-onu.
Imojula yokuthola i-onu isetshenziselwa: ukuvala umsebenzi wokwamukela ukukhanya kwemojula ye-optical ngesikhathi senqubo yokuqalisa ye-onu, nokuthola uhlobo lwemojula ye-optical ye-onu. Uma imojula ye-optical iyimojula ye-optical engalingani, yeka ukusebenza; uma imojula ye-optical iyimojula ye-optical elinganayo, lapho i-onu ishintsha isuka esimweni esingesona isibani iye esimweni sokukhanya, uhlobo lwemojula ye-optical ye-onu luyaphinde lutholakale:
Uma i-optical module iyi-symmetrical optical module, thola uhlobo lwe-optical module ye-onu. Uma i-optical module iyi-symmetrical optical module, nquma imodi yokusebenza yamanje ye-onu. Uma imodi yokusebenza ye-onu iyi-symmetrical mode, thumela iswishi yemodi ehambisanayo ku-symmetrical mode switching module Signal; uma imodi yokusebenza ye-onu iyi-asymmetric mode, thumela isignali yokushintsha imodi engafaniyo ku-asymmetric mode switching module, bese uvula umsebenzi wokwamukela ukukhanya kwe-optical module ngemva kokuthi i-onu iqale ukusebenza;
Uma i-optical module iyi-optical module engalingani, yeka ukusebenza.
