Incazelo yemidwebo
Umdwebo 1 uyi-flowchart yendlela yokuthi i-onu ivumelane ne-10g/10g symmetry kanye ne-asymmetry engu-10g/1g ekufanekiseni okusunguliwe kwamanje.
Izindlela ezinemininingwane
Okusunguliwe kwamanje kuzochazwa ngokuningiliziwe ngezansi ngokuhambisana nemidwebo ehambisana naso.
I-onu ekufanekisweni kokuqanjiwe kwamanje ijwayela ku-10g/10g symmetry kanye ne-asymmetry engu-10g/1g, futhi isetshenziswa kusimo se-gepon eyi-10.
Ngalesi sisekelo, njengoba kukhonjisiwe kuMfanekiso 1, i-onu ekufanekisweni kokuqanjiwe kwamanje ivumelana ne-10g/10g symmetry kanye ne-10g/1g asymmetry, okuhlanganisa nezinyathelo ezilandelayo:
s1: Uma i-onu iqala, thola uhlobo lwemojuli ye-optical ye-onu.Uma imojuli ye-optical iyimojuli ye-optical symmetrical, kusho ukuthi i-onu yamanje inamandla okusebenza kuzo zombili imodi yokulinganisa kanye nemodi ye-asymmetrical.Ngalesi sikhathi, iya ku-s2.Uma i-optical module ithi Imojuli ye-asymmetric optical isho ukuthi i-onu yamanje inamandla okusebenza kumodi ye-asymmetric.Ngalesi sikhathi, i-onu ingakwazi ukuzivumelanisa kuphela nemodi yokulinganisa engu-10g/10g, ngakho iphetha ngokuqondile ukunciphisa izindleko zokusebenza nokuthuthukisa ukusebenza kahle komsebenzi.
s2: Uma i-onu ishintsha isuka esimweni sokungakhanyi iye esimweni sokukhanya, thola kabusha uhlobo lwemojuli yokubona ye-onu.Uma imojuli ye-optical iyimojuli ye-optical symmetrical, iya ku-s3 (isizathu siyafana no-s1).Uma imojula ye-optical iyimojuli ye-asymmetrical optical, Bese uphetha ngokuqondile (isizathu siyafana no-s1).
Umgomo we-s2 uthi: isizathu sokuthi kungani i-onu ishintsha isuka esimweni esingakhanyisi iye esimweni sokukhanya ukuthi: imojula ye-optical ku-onu iyashintshwa, ngakho-ke uhlobo lwemojula yokubona ludinga ukutholwa futhi ukuze kuqinisekiswe ukuthi ikhono le-onu lokwaziwa ngokunembile.Ngaphezu kwalokho, ngenxa yokuthi kunesigcawu lapho i-onu ifakwa khona amandla lapho ixhunywe ku-fiber optical, i-onu ibilokhu ithola ukukhanya kwe-downlink okuthunyelwa i-olt, futhi ingase ingakwazi ukubona umcimbi oshintshayo ukusuka ku-no. -isimo esikhanyayo endaweni yokukhanya.Ngakho-ke, ukuze kuqinisekiswe ukuthi i-s2 can Igadwa ukuthi i-onu iyashintsha isuka esimweni esingakhanyi iye esimweni sokukhanya.Kuyadingeka ukuvala umsebenzi wokwamukela ukukhanya wemojula ye-optical ngesikhathi senqubo yokuqalisa i-onu ku-s1, bese uvula umsebenzi wokwamukela ukukhanya wemojula yokubona ngemva kokuqedwa kokuqaliswa kwe-onu.Dala umcimbi oshintsha i-onu isuke esimweni sobumnyama iye esimweni esikhanyayo.
Inqubo yokuthola uhlobo lwemojula ye-onu optical ku-s2 ithi: funda emuva irejista yemojuli ye-optical ngokusebenzisa i-i2c (ibhasi le-serial elilula, elinezintambo ezimbili elinezintambo ezimbili elakhiwe inkampani ye-philips) ukuze uthole ulwazi lohlobo lwe- imojuli ye-optical (uhlamvu lomkhiqizi nezinhlamvu eziyimodeli).Thola uhlobo lwemojula ye-optical ehambisanayo ngokusho kolwazi lohlobo.Inqubo ethize yilena: setha ngaphambilini isizindalwazi semojula ye-optical endaweni.Isizindalwazi semojula ye-optical sihlanganisa ulwazi lohlobo lwemojuli ye-optical kanye nohlobo oluhambisanayo.Uhlobo oluhambisanayo lusetshenziswa njengohlobo lwemojuli ye-optical.
s3: Thola imodi yokusebenza yamanje ye-onu.Uma imodi yokusebenza ye-onu iyimodi yokulinganisa, kuyadingeka ukunquma ukuthi i-onu kufanele iguqulelwe kumodi ye-asymmetric ngokuya nge-OLT, okungukuthi, ukuya ku-s4;uma imodi yokusebenza ye-onu iyimodi ye-asymmetric, kuzomele unqume ukuthi i-onu izoshintshela kumodi yokulinganisa ngokuya nge-olt, okungukuthi iya ku-s5.
s4: Thola ukuthi inani lezikhathi i-olt ethumela ngazo ulwazi lwefasitela ngemodi ye-asymmetric lingaphezu komkhawulo oshiwo (izahlulelo eziningi zibangelwa ukucatshangelwa kokuqina, izikhathi ezi-5 kulokhu kufanekiswa komuntu), futhi uma kunjalo, kufakazela ukuthi i-olt inakho kuphela. uplink 1g Amandla, okungukuthi, i-OLT ikumodi ye-asymmetric, ngalesi sikhathi, shintsha imodi yokusebenza ye-ONU isuke kumodi yokulinganisa iye kumodi ye-asymmetric, futhi igcine;ngaphandle kwalokho, kufakazela ukuthi i-OLT inamandla we-uplink 10g kuphela (okungukuthi, i-ONU ikhiphe ulwazi lwefasitela lwemodi yokulinganisa), Okusho ukuthi, i-olt isekela imodi ye-symmetric.Ngalesi sikhathi, imodi yokusebenza ye-onu iyagcinwa, futhi ukuphela kuphelile.
s5: Thola ukuthi ingabe inombolo yolwazi lwewindi oluthunyelwe yi-olt kumodi yokulinganisa ifinyelele umkhawulo oshiwo (izikhathi ezingu-5 kulokhu kufanekiselwa).Uma kunjalo, kufakazela ukuthi i-olt inamandla okuphakamisa u-10g, futhi ishintsha isuka kumodi ye-asymmetric iye kumodi yokulinganisa.Ngalesi sikhathi, shintsha imodi yokusebenza ye-onu ukusuka kumodi ye-asymmetric ukuya kumodi yokulinganisa, futhi uqede;ngaphandle kwalokho, kufakazela ukuthi i-OLT inamandla okuphakamisa i-1G kuphela, okungukuthi, i-OLT ikumodi ye-asymmetric, futhi ngalesi sikhathi, gcina imodi yokusebenza ye-onu, futhi uqede.
Ulwazi lwewindi lemodi ye-asymmetric ku-s4 kanye nolwazi lwewindi lwemodi yokulinganisa ku-s5 kutholakala kuhlaka lwe-mpcpgate olukhishwe yi-OLT.Ulwazi lwewindi lemodi ye-asymmetric wulwazi lwewindi le-uplink 1g, futhi ulwazi lwewindi lemodi yokulinganisa ulwazi lwewindi le-uplink 10g.
Uma kubhekiselwa ku-s1 kuye ku-s2, kungabonakala ukuthi ukuvezwa kwezinto ezisunguliwe kuthola ngokunembile uhlobo lwe-onu kuqala, futhi kubhekiselwa ku-s3 kuya ku-s5, kungabonakala ukuthi ukubonakaliswa kokusungulwa kwamanje kungathola indlela yokusebenza ye-onu. OLT, futhi uzivumelanise nokulungisa imodi yokusebenza ye-ONU ngokuya ngemodi yokusebenza ye-OLT, ukuze ubone ukujwayela okuphelele kwe-OLT ne-ONU, kanye nokungafani phakathi kwemodi yokugcina yendawo kanye nemodi yesiphetho esikude ubuciko bangaphambili ngeke kwenzeke.
I-onu ekufanekisweni kokusunguliwe kwamanje ijwayelana ne-10g/10g yamasistimu asymmetrical kanye ne-10g/1g asymmetrical, futhi ibonakala ngokuthi: isistimu ihlanganisa imojula yokuthola i-onu, imojula yokushintsha yemodi yokulinganisa, kanye nemojuli yokushintsha yemodi e-asymmetrical ehlelwe i-onu.
Imojula yokuthola i-onu isetshenziselwa: ukuvala umsebenzi wokwamukela ukukhanya wemojula yokubona ngesikhathi senqubo yokuqalisa i-onu, nokuthola uhlobo lwemojula yokubona ye-onu.Uma imodyuli ye-optical iyimojuli ye-asymmetric optical, yeka ukusebenza;uma i-optical module iyimodule ye-optical symmetrical, lapho Uma i-onu ishintsha isuka esimweni esingakhanyi iye endaweni yokukhanya, uhlobo lwemojula ye-optical ye-onu iphinda itholakale:
Uma imojuli ye-optical iyimojuli ye-optical symmetrical, thola uhlobo lwemojuli yokubona ye-onu.Uma imojula yokubona iyimojuli ye-optical elinganayo, nquma imodi yokusebenza yamanje ye-onu.Uma imodi yokusebenza ye-onu iyimodi yokulinganisa, thumela ukushintshwa kwemodi ye-symmetrical kumojuli yokushintsha imodi yokulinganisa Isignali;uma imodi yokusebenza ye-onu iyimodi ye-asymmetric, thumela isignali yokushintsha imodi ye-asymmetric kumojula yokushintsha imodi ye-asymmetric, bese uvula umsebenzi wokwamukela ukukhanya we-optical module ngemva kokuba i-onu iqalile;
