(1) Indlela yophuhliso lweTekhnoloji ye-PON ye-10G
I-EPON elawulwa yi-IEEE, kunye ne-GPON elawulwa yi-ITU zombini ziguqukela kwi-10 isigaba se-GPON okwangoku kwaye ukucwangciswa okulandelayo kuzo zombini i-100G PON. Kukho iiyantlukwano ezithile kwiindlela ezithile zokuzivelela, kwaye indlela yendaleko ehambelana nayo iboniswe kulo mfanekiso ulandelayo:
(2) Ukuziphendukela kweteknoloji ye-EPON
I-10G EPON imigangatho ye-symmetric kunye ne-asymmetric yezobugcisa kunye neemveliso ziye zafezekiswa, Ukongeza, inenzuzo yokuhlala kunye ne-terminal ye-EPON kwinethiwekhi ye-ODN efanayo ngaphandle kokongeza i-multiplexer. Emva kokuthengwa kwempahla ephakathiOLTngo-2016, iimodyuli zamehlo ze-OLT ze-OLT ze-10G ziye zacuthwa kwixabiso.
. Ukuqwalasela ukuguquka kwexesha elizayo lomnatha, abaqhubi baqala ukuphuhlisa i-10G EPON kwangaphambili ekupheleni kwendawo, kwaye basasebenzisa i-EPON ONT kumxhasi ukuphumeza ukwakhiwa kwe-FTTH. Ngexesha elifanayo, ngenxa yokuba umehluko wexabiso phakathi kwemodyuli ye-symmetric optical kunye nemodyuli ye-asymmetric optical ayinkulu, kwaye ukuqwalasela umlinganiselo we-bandwidth ye-asymmetric 10G EPON phezulu kunye ne-downstream link yi-1: 10, ukuze ugweme imfuno yokuphucula ebangelwa yilandelayo. uphuhliso lwenkonzo ye-uplink, abaqhubi bathambekele ngakumbi ekusebenziseni i-10G EPON imo ye-symmetricOLTicala. Inyathelo elilandelayo le-EPON liya kuguqukela kwitekhnoloji ye-PON ye-100G.
(3) Ukuziphendukela kweteknoloji yeGPON
Ngomgangatho we-10G GPON, umgangatho wezobugcisa we-XG-PON we-asymmetric kunye neemveliso ziye zagqitywa. I-wavelength esisigxina ye-symmetric ye-10G GPON standard XGS-PON yakhululwa ngoFebruwari 2016. Ngenxa yezixhobo ezivuthiweyo ezibandakanyekayo kumgangatho, ezinye iimveliso zabavelisi zilungele ukusetyenziswa kwezorhwebo. Umgangatho we-NGPON2 (TWDMPON) kunye ne-wavelength ehlengahlengiswayo igqitywe. Ngoku,OLTiimveliso ziye zafumaneka kurhwebo eYurophu naseMelika.Ngexesha elifanayo, kukho iimveliso ze-MDU ezihambelana neshishini elizinikeleyo kwimakethi yomgca. Imodyuli ye-optical ene-adjustable wavelength ye-NGPON2 iyabiza kwaye inzima ukuyifeza.Emva kokuba i-ITU yongezelela i-symmetrical fixed wavelength ye-10G standard (XGS-PON), abanye abavelisi bakholelwa ukuba i-NGPON2 inokugqithwa kwaye iguquke ngokuthe ngqo kwi-4 * 25G 100G isisombululo se-PON, kwaye kunokwenzeka ukudibanisa kunye nomgangatho we-EPON we-100G.
Ngexesha elifutshane, ixabiso le-ONT le-10G PON aliyi kuwela kwinqanaba elikhoyo lexabiso le-EPON / GPON, ngoko ke akunakuphepheka ukujamelana nesimo sokuhlalisana kwe-10 GPON kunye necala lomsebenzisi i-EPON / GPON terminal. Ngenxa yokuba ii-terminals ze-GPON kunye ne-XGPON zihlala kwinethiwekhi efanayo ye-ODN, iimodyuli ze-WDM1r kufuneka zongezwe, ezikhawulela ukuthunyelwa kwe-XG-PON kwinethiwekhi yangoku. Ngoko ke, abavelisi abanenzuzo banesicwangciso se-Combo PON ye-encapsulate GPON kunye ne-XGPON iimodyuli ze-optical kunye ne-WDM1r kwimodyuli enye ye-optical. Nangona kunjalo, imodyuli ye-Optical ye-Combo PON scheme inokupakishwa kuphela yi-XFP, kwaye ibhodi enye inokuqonda kuphela i-8 ye-PON port (eqhelekileyo).SFP+ ukupakishwa, kunye nebhodi enye inokuqonda izibuko ezili-16 zePON). Okwangoku, ngenxa yokunyuka kwelahleko yokufaka i-WDM1r, iimfuno zamandla ezikhanyayo zeemodyuli ze-optical ziphezulu. Okwangoku, amandla akhanyayo e-B +/N1 anokuphunyezwa kuphela, kwaye imodyuli yamandla aphezulu e-C +/N2a ayinakubonelelwa ngexesha elifutshane, elinciphisa ukusetyenziswa kweemeko ze-spectral ratio ende.
Oku ngasentla yinkcazo ye-EPON kunye nokuziphendukela kwezobuchwepheshe. Iimveliso zothungelwano ze-Shenzhen HDV photoelectron Technology Co., Ltd. zonke izixhobo eziveliswe malunga nenethiwekhi yePON, kubandakanywaI-ONUuthotho /OLTuthotho / uthotho lweemodyuli zokukhanya / uthotho lwe-transceiver njalo njalo. Ukuze udale izixhobo zenethiwekhi ezigqwesileyo, inkampani yethu ixhotyiswe ngophando lobuchwephesha kunye neqela lophuhliso, ukubonelela abathengi ngeenkonzo zenkxaso yobugcisa obuphezulu, bamkelekile ukuba bafune abasebenzi ukuba baqonde iimveliso zethu.
