Inkcazo yemizobo
Umzobo 1 yitshathi yendlela yokuba i-onu ikwazi ukuziqhelanisa nokulingana kwe-10g/10g kunye nokungalingani kwe-10g/1g kwindlela yokubonakalisa olu vumbululo.
Iindlela ezineenkcukacha
Olu vumbululo luza kuchazwa ngokweenkcukacha ezithe vetshe ngezantsi kunye nemizobo kunye neendlela ezisetyenziswayo.
I-onu ekusetyenzisweni kwale nto intsha iyaziqhelanisa nokulingana kwe-10g/10g kunye nokungalingani kwe-10g/1g, kwaye isetyenziswa kwimeko ye-10gepon.
Ngokwale njongo, njengoko kubonisiwe kuMfanekiso 1, i-onu ekusetyenzisweni kwale nto intsha iyaziqhelanisa nokulingana kwe-10g/10g kunye nokungalingani kwe-10g/1g, kuquka la manyathelo alandelayo:
s1: Xa i-onu iqala, fumana uhlobo lwemodyuli ye-optical ye-onu. Ukuba imodyuli ye-optical yimodyuli ye-optical elinganayo, oko kuthetha ukuba i-onu yangoku inako ukusebenza kwimo yokulinganisa kunye nemo yokungalingani. Ngeli xesha, yiya ku-s2. Ukuba imodyuli ye-optical yi-Imodyuli ye-optical engafaniyo ithetha ukuba i-onu yangoku inako ukusebenza kwimo yokungalingani. Ngeli xesha, i-onu inokuqhelana kuphela nemo yokulinganisa ye-10g/10g, ngoko ke iphelela ngokuthe ngqo ekunciphiseni iindleko zokusebenza kunye nokuphucula ukusebenza kakuhle komsebenzi.
s2: Xa i-onu itshintsha ukusuka kwimeko yokungakhanyi ukuya kwimeko yokukhanya, phinda ufumane uhlobo lwemodyuli ye-optical ye-onu. Ukuba imodyuli ye-optical yimodyuli ye-optical elinganayo, yiya ku-s3 (isizathu siyafana ne-s1). Ukuba imodyuli ye-optical yimodyuli ye-optical engalinganiyo, Emva koko phelisa ngokuthe ngqo (isizathu siyafana ne-s1).
Umgaqo we-s2 ngulo: isizathu sokuba i-onu itshintshe ukusuka kwimeko yokungakhanyi ukuya kwimeko yokukhanya kukuba: imodyuli ye-optical kwi-onu iyatshintshwa, ngoko ke uhlobo lwemodyuli ye-optical kufuneka luphinde lufunyanwe ukuqinisekisa ukuba i-onu iyakwazi ukwaziwa ngokuchanekileyo. Ukongeza, kuba kukho indawo apho i-onu ivuliwe khona xa iqhagamshelwe kwi-optical fiber, i-onu ibisoloko ifumana ukukhanya kwe-downlink okuthunyelwa yi-olt, kwaye isenokungakwazi ukubona isiganeko esitshintsha ukusuka kwimeko yokungakhanyi ukuya kwimeko yokukhanya. Ke ngoko, ukuqinisekisa ukuba i-s2 iyakwazi Kujongwa ukuba i-onu itshintsha ukusuka kwimeko yokungakhanyi ukuya kwimeko yokukhanya. Kubalulekile ukucima umsebenzi wokwamkela ukukhanya wemodyuli ye-optical ngexesha lenkqubo yokuqalisa ye-onu kwi-s1, uze uvule umsebenzi wokwamkela ukukhanya wemodyuli ye-optical emva kokuba ukuqalisa kwe-onu kugqityiwe. Yenza isiganeko apho i-onu itshintsha ukusuka kwimeko emnyama ukuya kwimeko yokukhanya.
Inkqubo yokufumana uhlobo lwemodyuli ye-onu optical kwi-s2 yile: funda kwakhona irejista yemodyuli ye-optical nge-i2c (ibhasi ye-serial elula, eneendlela ezimbini edibeneyo eyenziwe yinkampani ye-philips) ukuze ufumane ulwazi lohlobo lwemodyuli ye-optical (uphawu lomenzi kunye noonobumba bemodeli). Fumana uhlobo lwemodyuli ye-optical ehambelanayo ngokweenkcukacha zohlobo. Inkqubo ethile yile: seta kwangaphambili isiseko sedatha semodyuli ye-optical kwindawo. Isiseko sedatha semodyuli ye-optical siquka ulwazi lohlobo lwemodyuli ye-optical kunye nohlobo oluhambelanayo. Uhlobo oluhambelanayo lusetyenziswa njengohlobo lwemodyuli ye-optical.
s3: Chonga indlela yokusebenza yangoku ye-onu. Ukuba indlela yokusebenza ye-onu ikwimo yokulinganisa, kuyimfuneko ukumisela ukuba i-onu kufuneka iguqulwe ibe yimo yokungalingani ngokwe-OLT, oko kukuthi, yiya kwi-s4; ukuba indlela yokusebenza ye-onu yimo yokungalingani, kufuneka umisele ukuba i-onu iza kutshintshela kwimo yokungalingani ngokwe-olt, oko kukuthi yiya kwi-s5.
s4: Qinisekisa ukuba inani lamaxesha i-olt ethumela ulwazi lwefestile kwimo ye-asymmetric lingaphezulu komda ochaziweyo (izigwebo ezininzi zibangelwa kukuqwalaselwa kokuqina, amaxesha ama-5 kolu hlobo lokwenziwa), kwaye ukuba kunjalo, kungqina ukuba i-olt ine-uplink 1g kuphela. Amandla, oko kukuthi, i-OLT ikwimo ye-asymmetric, ngeli xesha, tshintsha imo yokusebenza ye-ONU ukusuka kwimo ye-symmetric ukuya kwimo ye-asymmetric, kunye ne-end; kungenjalo, kungqina ukuba i-OLT inamandla e-uplink 10g kuphela (oko kukuthi, i-ONU ikhuphe ulwazi lwe-window lwemo ye-symmetric), Oko kukuthi, i-olt ixhasa imo ye-symmetric. Ngeli xesha, imo yokusebenza ye-onu iyagcinwa, kwaye isiphelo siphelile.
s5: Fumana ukuba inani lolwazi lwefestile oluthunyelwe yi-olt kwimowudi yokulinganisa lifikelele kumda ochaziweyo (amaxesha ama-5 kolu hlobo lokwenziwa). Ukuba kunjalo, kungqina ukuba i-olt inamandla okuphakamisa i-10g, kwaye itshintsha ukusuka kwimowudi yokungalingani ukuya kwimowudi yokulinganisa. Ngeli xesha, tshintsha imo yokusebenza ye-onu ukusuka kwimowudi yokungalingani ukuya kwimowudi yokulinganisa, kwaye iphele; kungenjalo, kungqina ukuba i-OLT inamandla okuphakamisa i-1G kuphela, oko kukuthi, i-OLT ikwimowudi yokungalingani, kwaye ngeli xesha, gcina imo yokusebenza ye-onu, kwaye iphele.
Ulwazi lwefestile lwemo ye-asymmetric kwi-s4 kunye nolwazi lwefestile lwemo ye-symmetric kwi-s5 lufumaneka kwisakhelo se-mpcpgate esikhutshwe yi-OLT. Ulwazi lwefestile lwemo ye-asymmetric lulwazi lwe-uplink 1g window, kwaye ulwazi lwefestile lwemo ye-symmetric lulwazi lwe-uplink 10g window.
Ngokubhekiselele kwi-s1 ukuya kwi-s2, kunokubonwa ukuba indlela evezwe ngayo le nto intsha ifumana ngokuchanekileyo uhlobo lwe-onu kuqala, kwaye ngokubhekisele kwi-s3 ukuya kwi-s5, kunokubonwa ukuba indlela evezwe ngayo le nto intsha inokuyibona indlela yokusebenza ye-OLT, kwaye ihlengahlengise ukulungisa indlela yokusebenza ye-ONU ngokwendlela yokusebenza ye-OLT, ukuze kufezekiswe uhlengahlengiso olugqibeleleyo lwe-OLT kunye ne-ONU, kwaye ukungafani phakathi kwendlela yokuphela yendawo kunye nendlela yokuphela ekude kubugcisa bangaphambili akuyi kwenzeka.
I-onu ekuyimbonakaliso yale nto intsha iyaziqhelanisa neenkqubo ze-10g/10g ezilinganayo kunye ne-10g/1g ezingafaniyo, kwaye ichazwa ngokuba: inkqubo ibandakanya imodyuli yokufumanisa i-onu, imodyuli yokutshintsha imowudi elinganayo, kunye nemodyuli yokutshintsha imowudi engafaniyo ecwangciswe kwi-onu.
Imodyuli yokufumanisa i-onu isetyenziselwa: ukucima umsebenzi wokufumana ukukhanya kwemodyuli ye-optical ngexesha lenkqubo yokuqalisa ye-onu, kwaye ufumane uhlobo lwemodyuli ye-optical ye-onu. Ukuba imodyuli ye-optical yimodyuli ye-optical engalinganiyo, yeka ukusebenza; ukuba imodyuli ye-optical yimodyuli ye-optical elinganayo, xa Xa i-onu itshintsha ukusuka kwimeko engeyiyo yokukhanya ukuya kwimeko yokukhanya, uhlobo lwemodyuli ye-optical ye-onu luyaphinda lufunyanwe:
Ukuba imodyuli yokukhanya iyimodyuli yokukhanya elinganayo, fumana uhlobo lwemodyuli yokukhanya ye-onu. Xa imodyuli yokukhanya iyimodyuli yokukhanya elinganayo, misela imo yokusebenza yangoku ye-onu. Ukuba imo yokusebenza ye-onu yimo yokusebenza elinganayo, thumela iswitshi yemo yokukhanya elinganayo kwimodyuli yokutshintsha imo yokulinganisa iSignali; ukuba imo yokusebenza ye-onu yimo yokusebenza elinganayo, thumela isignali yokutshintsha imo yokulinganisa ingafani kwimodyuli yokutshintsha imo yokulinganisa ingafani, kwaye uvule umsebenzi wokwamkela ukukhanya kwemodyuli yokukhanya emva kokuba i-onu iqalile;
Ukuba imodyuli ye-optical yimodyuli ye-optical engalinganiyo, yeka ukusebenza.
Imodyuli yokutshintsha imowudi elinganayo isetyenziselwa: emva kokufumana isignali yokutshintsha imowudi elinganayo, gweba ukuba inani lolwazi lwefestile olukhutshwe yi-olt kwimowudi engafaniyo lifikelela kumda othile okanye akunjalo, kwaye ukuba kunjalo, tshintsha imo yokusebenza ye-onu ukusuka kwimowudi elinganayo ukuya kwimowudi engafaniyo; Ngaphandle koko gcina imo yokusebenza ye-onu;
