(1) 10G PON Inzira yiterambere ryikoranabuhanga
EPON yiganjemo IEEE, na GPON yiganjemo ITU byombi bigenda bihinduka kuri 10 GPON kuri presnt kandi igenamigambi ryakurikiyeho ni 100G PON. Hariho itandukaniro munzira zihariye zubwihindurize, kandi inzira ihindagurika yerekanwe mubishusho bikurikira:
(2) Ubwihindurize bwa tekinoroji ya EPON
Ibipimo bya tekiniki ya 10G EPON hamwe na asimmetric tekiniki nibicuruzwa byarakozwe neza, Byongeye kandi, ifite ibyiza byo kubana na terefone ya EPON mumurongo umwe wa ODN utiriwe wongeraho multiplexer. Nyuma yamasoko yibanze yaOLTmuri 2016, modul ya 10G PON ya OLT yagabanijwe kubiciro
. Urebye ubwihindurize bw'ejo hazaza, abashoramari batangiye gukora 10G EPON hakiri kare, kandi bagikoresha EPON ONT mubakiriya kugirango bakore FTTH. Muri icyo gihe, kubera ko itandukaniro ryibiciro hagati yuburyo bwa optique na modulike ya optique itari nini, kandi urebye igipimo cyagutse cya asimmetric 10G EPON hejuru no kumanuka ni 1:10, kugirango wirinde icyifuzo cyo kuzamura cyatewe nicyakurikiyeho kuzamura serivise yiterambere, abashoramari barushijeho gukoresha uburyo bwa 10G EPON muburyo bwa simmetrike muriOLTruhande. Intambwe ikurikira kuri EPON izahinduka yerekeza kuri tekinoroji ya 100G PON.
(3) Ubwihindurize bwa tekinoroji ya GPON
Kubisanzwe 10G GPON, ibipimo bya tekinike ya XG-PON nibicuruzwa byakozwe neza. Uburebure bwumurongo wa 10G GPON usanzwe XGS-PON yasohotse muri Gashyantare 2016. Kubera ibikoresho bisa nkaho bikuze bigira uruhare mubisanzwe, ibicuruzwa bimwe nababikora biteguye gukoreshwa mubucuruzi. Igipimo cya NGPON2 (TWDMPON) gifite uburebure bwumurongo ushobora guhinduka. Kugeza ubu,OLTibicuruzwa byabonetse mubucuruzi muburayi no muri Amerika.Mu gihe kimwe, hari ibicuruzwa bya MDU bihuye kumasoko yihariye yumurongo. Module ya optique ifite uburebure bwumurongo wa NGPON2 ihenze kandi biragoye kubigeraho.Nyuma yuko ITU yuzuzanya nuburinganire bwa 10G busanzwe (XGS-PON), abayikora bamwe bemeza ko NGPON2 ishobora gusimbuka hanyuma igahinduka muburyo bwa 4 * 25G 100G PON, kandi birashoboka guhuza hamwe na 100G EPON isanzwe.
Mugihe gito, igiciro ONT ya 10G PON ntikizagabanuka kurwego rusanzwe rwa EPON / GPON, kubwibyo byanze bikunze duhura nikibazo cyo kubana kwa 10 GPON hamwe nabakoresha EPON / GPON. Kuberako GPON na XGPON zibana zibana mumurongo umwe wa ODN, modul ya WDM1r igomba kongerwamo, igabanya kohereza XG-PON mumurongo uriho. Kubwibyo, abahinguzi bafite inyungu bafite gahunda ya Combo PON ya encapsulate GPON na XGPON optique na WDM1r muburyo bumwe. Nyamara, module ya optique ya gahunda ya Combo PON irashobora gupakirwa gusa na XFP, kandi ikibaho kimwe gishobora kumenya ibyambu 8 PON gusa (bisanzwe)SFP+ gupakira, kandi ikibaho kimwe gishobora kumenya ibyambu 16 PON). Hagati aho, kubera kwiyongera kwa WDM1r igihombo cyo gushiramo, ingufu zamashanyarazi zisabwa modul optique ziri hejuru. Kugeza ubu, imbaraga zamurika za B + / N1 zishobora kugerwaho gusa, kandi C + / N2a module yo hejuru ntishobora gutangwa mugihe gito, igabanya ikoreshwa ryintera ndende nini yerekana ibintu.
Ibyavuzwe haruguru nibisobanuro bya EPON nihindagurika ryikoranabuhanga. Ibicuruzwa byurusobe rwa Shenzhen HDV fotoelectron Technology Co., Ltd nibikoresho byose bikorerwa hafi ya PON, harimoONUurukurikirane /OLTurukurikirane / optique module ikurikirana / transceiver ikurikirana nibindi. Kugirango dushyireho ibikoresho byiza cyane byurusobe, isosiyete yacu ifite ibikoresho byitsinda ryubushakashatsi niterambere ryumwuga, kugirango duhe abakiriya serivisi nziza zo gufasha tekinike nziza, murakaza neza kugirango abakozi basobanukirwe nibicuruzwa byacu.
