I-10G ye-PON yokusasazwa kweTekhnoloji:
Okwangoku, ukwakhiwa kwe-broadband ikakhulu yi-FTTH, kodwa ukwakhiwa kwe-10G PON kusalawulwa yi-10G PON + LAN.Izixeko ezinjengeBeijing, iShanghai, iGuangzhou kunye neShenzhen, apho i-FTTH isetyenziswa kwangethuba, sele iqalisile ukujongana nemfuno yokuphuculwa kwenethiwekhi ye-FTTH yokuqala.Nangona kunjalo, ngenxa yeentlobo ezincinci kunye nexabiso eliphezulu lee-terminals kwi-10G PON ONT, i-10G PON isetyenziswa kakhuluOLTicala kwixesha elifutshane, ngelixa icala le-terminal lisasebenzisa ubukhulu becala i-EPON / GPON terminals ukunyusa inkxaso ye-GE port, kunye nokubonelela ngenkonzo yasekhaya ye-gigabit kwinani elincinci labasebenzisi.Kwixesha elizayo, kunye nokuthandwa kwabasebenzisi be-high-bandwidth, kunye nesikali se-terminals ye-PON ye-10G kunye nokuhla kwexabiso, ukusetyenziswa kwesikali se-10G PON FTTH kuya kukhuthazwa ngokuthe ngcembe.Okwangoku, ukuhanjiswa kwesikali se-10G EPON kwiOLTicala lilungile, kunye nokuthunyelwa kwe-XG (S) -PON kwiOLTidinga ukuvuthwa yiCombo PON.Ngenxa yezithintelo zokuphunyezwa komgangatho wobugcisa, ixabiso le-Combo PON liphezulu kakhulu kune-10G EPON.Ukongeza, yenza lula umgangatho we-XGPON, usebenzisa i-wavelength efanayo ne-10G EPON ngaloo ndlela ukususa i-WDM1r kwinethiwekhi ye-ODN.Kwakhona yindlela enokwenzeka yokubingelela i-bandwidth ukuhlalisana ne-GPON ONT, kodwa kufuneka ikhuthaze ukuguqulwa komgangatho we-XG-PON.
Izixhobo zabavelisi abangaxhasi i-10G yekhadi lebhodi ye-PON kwinethiwekhi yangoku kufuneka ithathelwe indawo ngokuthe ngcembe, kwaye izixhobo ezingentla zifanele zisuswe ngokuthe ngcembe ngokusebenzisa ukufuduka komsebenzisi kwezinye i-OLT kunye nokutshintshwa kwezixhobo ngokubanzi.
Iingcebiso eziyeleleneyo zokusasazwa kobugcisa:
Okwangoku, inethiwekhi ye-PON iphethe iinkonzo ezahlukeneyo ezifana ne-broadband, ilizwi, usasazo lwe-IPTV, i-IPTV efunwayo kunye nomgca ozinikeleyo.Kwangaxeshanye, inethiwekhi ye-PON ithwala ulwazi lolawulo lwenethiwekhi yezixhobo ze-PON kunye namasango asekhaya, kwaye inokuphatha ukubuyiswa kweselula kunye neenkonzo ze-prequel kwixesha elizayo.Ngokunyuka kweentlobo zeshishini kunye nenani elincinci labasebenzisi phantsi kwe-PON port enye (ishumi ukuya kwishumi elinesibini), i-traffic port ye-PON enye ineempawu zokuqina ngokukhawuleza kunye nokungaqiniseki okukhulu.Indlela yokuqala yokubala i-traffic ngokwemodeli yeshishini ayisalungiswa kwiimpawu zendlela ye-PON network.Kucetyiswa ukuba inethiwekhi ye-PON kufuneka yamkele ezi zicwangciso zobuchwepheshe zilandelayo zokusasazwa ukwandisa i-bandwidth yenethiwekhi kunye nokuphucula amava omsebenzisi.
① Uthungelwano lofikelelo lwenkonzo ye-IPTV isasazwe ngokupheleleyo ngomaleko wesi-2 wokusasazwa okuninzi, ngeOLTkuthunyelwa i-IGMPProxy kunye ne-ONU ithumela i-IGMP Snoop-ing ukunciphisa ukusetyenziswa kwe-bandwidth ye-PON port.
② Inethiwekhi yokufikelela kwi-broadband isebenzisa iteknoloji ye-QoS esekelwe kwi-802.1p, ibeka phambili ekuqinisekiseni ukuthunyelwa kweenkonzo eziphambili.
③ Isango lasekhaya kunye nebhokisi yokuseta-phezulu iye yakha-ngaphakathi probe ethambileyo, kwaye isebenzisane nenkqubo yoqwalaselo lwetrafikhi yothungelwano kunye nenkqubo yohlalutyo (efana neHuawei uTraffic, iZTE BigDNA, njl. njl.) ukuqonda uhlolo oluguqukayo kwinqanaba leshishini kunye nenqanaba lothungelwano.
Izibuko ze-PON ezingenakukwazi ukuhlangabezana neemfuno ze-bandwidth ngokusebenzisa izicwangciso zobugcisa ezingentla kufuneka zihlengahlengiswe ngokulungelelanisa ukuhanjiswa komsebenzisi, ukunciphisa umlinganiselo wokuhlukana kwe-optical kunye nokuphucula i-PON ye-10G.
Ezi ngasentla ziziphakamiso kwi-10G PON iteknoloji yokuthunyelwa kwenethiwekhi kunyeOLTindaleko eziswa Shenzhen HDV Phoelectron Technology Co., LTD.Shenzhen HDV Phoelectron Technology Co., LTD.inehardware eyomeleleyo kunye namandla esoftware, kwaye ezona mveliso zithengiswayo zishushu zezi:
OLTizixhobo: i-olt ye-rack, i-olt encinci, i-compact olt, i-olt switch, imodyuli ye-olt, i-olt yonxibelelwano, njl.
I-ONUizixhobo: olt onu, ac onu, onu okrelekrele, unxibelelwano onu, ekhaya onu,
Tshintshela izixhobo: I-Ethernet switch, iswitshi yonke-optical, i-8 port switch,
