Hamwe no kohereza no gushyira mubikorwa uburyo bwiza bwo guhindura umurongo mugari, ubwiza bwurusobe buratera imbere, igipimo cyo gutsindwa kiragabanuka, kandi igitekerezo cyumukoresha cyiyongereye. Kugeza ubu, ishyirwaho ryumuyoboro mugari wiganjemo FTTH kandi ryuzuzwa na PON + LAN. Niba umuyoboro mugari uzaza ukoresha tekinoroji ya PON yo guhuza imiyoboro, ntishobora gutanga gusa ubunararibonye bwabakoresha ubuziranenge, ariko kandi igabanya ibiciro byumushinga no kuzamura inyungu zubukungu. Ibikurikira, iyi ngingo izatanga ibyifuzo byiterambere rya tekiniki no kohereza 10G PON ukurikije ibisabwa mubucuruzi.
Umuyoboro wa PON ni iki
Umuyoboro wa PON ugizweOLT, ODN naONU. AnOLTigikoresho ni ishingiro ryurusobe topologiya. Igera kumurongo wa serivise nyinshi hejuru na serivisi zabakoresha benshi hepfo binyuze muri ODN. Nibyingenzi byingenzi byo gukusanya serivisi no gukwirakwiza.OLTicyarimwe imenya ibikorwa byinshi byo kuyobora imiyoboro nko kugenzura, kuyobora, kuringaniza nibindi kubikoresho byabakiriyaONU. OLTibikoresho biri mumutima wumuyoboro wa PON, haba mubijyanye nurusobe rwabo hamwe nubushobozi bwurusobe. Nka serivisi nyinshi kandi nyinshi nka enterineti, videwo ya 4K IPTV, serivise zo murugo zifite ubwenge, imishinga mito n'iciriritse yumushinga wigenga, ijwi rya IMS, hamwe na terefone igendanwa bikorerwa kumurongo wa PON, icyifuzo cyumurongo hamwe nurwego rwo kunonosora. ubuyobozi bukomeje kwiyongera. Iterambere rya tekinoroji ya PON hamwe no kohereza ubwihindurize bwaOLTibikoresho bigira uruhare runini mugutezimbere imiyoboro yagutse ..
Isesengura ryimiterere ya PON
(1)OLTkohereza ibikoresho
UwitekaOLTibikoresho byabakozi bo murugo ahanini byatangiye koherezwa mumwaka wa 2006, kandi ahanini byakoreshwaga muburyo bwa PON + DSL mubyiciro byambere. Haraheze imyaka irenga 10 kuva FTTH itangiye koherezwa murwego runini mumwaka wa 2009. Ukurikije umurongo wa interineti, ubushobozi bwo guhinduranya muri rusange, hamwe nubuyobozi bwa PON, hari ibisekuruza 2-3 byibicuruzwa bikoreshwa kumurongo wa Live. Kumurongo wa Live, ubushobozi bwo guhinduranya umwanya umwe wigikoresho nyamukuru gisunika kigera kuri 40 Gbit / s kandi gishyigikira 10 Gbit / s EPON na XG-PON1.
(2) Ikoreshwa rya tekinoroji ya PON
Hamwe na tekinoroji ya 10G PON igenda igurishwa, imbaho za PON zagizwe kuriOLTibikoresho muri rezo nzima bigabanijwemo EPON, GPON, 10G EPON na XG-PON, muri byo EPON na GPON nibyo byingenzi. Mu rwego rwo kuzamura Ubushinwa Telecom na China Unicom mu rwego rwo kunoza igipimo cya EPON, imikoreshereze y’ubucuruzi ya EPON n’abakora mu gihugu yari hafi imyaka 2-3 mbere ya GPON. Mbere ya 2013, iyubakwa ryiganjemo EPON, nyuma, kubera ibyiza ya GPON mumurongo mugari, yiganje buhoro buhoro kubakaOLT. Urebye uburyo bwo kohereza imiyoboro isanzwe, Ubushinwa Unicom na China MobileOLTibikoresho ni GPON, naho Ubushinwa Telecom ni EPON.
Kubaka 10G PON byatangiye ahagana mu 2015. Kubera igiciro kinini cya modul optique ya 10G, igiciro cya 10G PON ONT nikubye inshuro eshanu icy'ibisanzwe bya EPON / GPON. Mubidukikije bigezweho aho itumanaho risanzwe ritangwa nuwabikoresheje kubakiriya, kandi serivisi isabwa iri munsi ya 100Mbit / s, abashoramari bakomeye bafite amakenga kubijyanye no kohereza porogaramu 10G PON. Kugeza ubu, uburyo bwo kubaka 10G PON bukoreshwa cyane cyane muri 10G PON + LAN na FTTH yoherejwe. 10G PON + LAN ni uguhindura cyane cyane umuyoboro wa LAN uriho hamwe numuyoboro wa PON + LAN. Ku ruhande rumwe, ukemure ikibazo cyagutse cyatewe numubare munini wabakoresha; Ku rundi ruhande, kubera ko abakoresha benshi basangiye igiciro cya optique muri MDU, igiciro rusange ntabwo cyiyongera cyane ugereranije numuyoboro wa PON + LAN, bityo rero washyizwe mubikorwa, kandi tekiniki 10G PON na XG-PON irakoreshwa . Kubaka 10G PON FTTH ahanini ni umuderevu wurugo wa gigabit ukorwa nabakozi batandukanye, kandi intego nyamukuru nukumenyekanisha no kugenzura ibicuruzwa bya 10G PON FTTH.
Hafi ya 10G (icumi gigabit) Ikoranabuhanga rya Ethernet no kuyikoresha ni ingingo zubumenyi zavuzwe haruguru, kubyerekeyeOLTibikoresho byavuzwe haruguru byavuzwe muri Shenzhen HDV Phoelectron Technology Ltd ni mubyiciro bizwi cyane byibicuruzwa byitumanaho, nka:OLT hindura, GPONOLT, EPONOLT, injangwe yorohejeOLT, n'ibindi, hejuruOLTibikoresho birashobora gukoreshwa mubidukikije bitandukanye, kubikenerwa bitandukanye byabakoresha kugirango batange amahitamo menshi, ikaze kugirango ubyumve, tuzatanga serivise nziza nziza.
