Mu Bushinwa, umurongo mugari wa 100M optique umaze kumenyekana, kandi igihe cya Gigabit kiri hafi gufungura.Muri 2019, Minisiteri y’inganda n’ikoranabuhanga mu itumanaho yatangije igikorwa cya “Double G Double Lifting, Same Network Same Speed Speed” igamije imiyoboro migari, kandi ikomeza kwihutisha iterambere ry’imikorere ihamye ya porogaramu ya Gigabit.10G Ikoranabuhanga rya GPON rishobora kugera ku gusimbuka kuva “ijana megabytes ”kuri“ gigabit ”.Ubuhanga bwa 10G GPON bivuga ikoranabuhanga nka XG-PON, XG-PON & GPON Combo, XGS-PON, XGS-PON & GPON Combo.Ubwihindurize kuri 10G GPON bukeneye gusuzuma ibibazo bihuza ONU zitandukanye.
Mu rwego rwo gukemura ikibazo cyuko XG-PON idahuye na GPON ONU, ZTE niyambere itanga ikoranabuhanga rishya rya Combo PON kugirango tumenye XG-PON & GPON Combo. Kugeza ubu, ubu buhanga bwihuse bwa Combo PON bwabaye. yakirwa nabakoresha kubera guhuza neza no korohereza.Byahindutse igisubizo nyamukuru cyo kubaka 10G GPON kandi iraboneka mubucuruzi ku rugero runini.
Ubu tekinoroji ya XGS-PON yarakuze, kandi XGS-PON irashobora gutanga 10G yumurongo wo hejuru no kumurongo wo hasi, ariko XGS-PON OLT irashobora guhuza gusa na XGS-PON na XG-PON ubwoko bubiri bwa ONU, mugihe umubare munini wa GPON na ONU boherejwe mumurongo uriho, kandi guhuza imiyoboro ihari GPON na ONU bigomba gukemuka mugihe umuyoboro uhindutse kuri XGS-PON. Kugirango iki kibazo gikemuke, ZTE yatanze tekinoroji ya Combo yibiciro bitatu, aribyo XGS-PON na GPON gushyira mubikorwa Combo, ishyigikira kuzamura neza GPON kuri XGS-PON.
Ihame ryibiciro bitatu Combo PON ihame ryikoranabuhanga
XGS-PON & GPON's Combo PON igisubizo nigisubizo cyubatswe muri multiplexer gishyigikira XGS-PON / XG-PON / GPON uburyo butatu bwo kubana.Inganda nayo yita "umuvuduko wihuta wa Combo PON", izwi ninganda nkinganda igisubizo cyiza cyo kuzamura neza GPON kuri XGS-PON.
Ibipimo bitatu bya Combo PON ikoresha ihame ryuburebure butandukanye bwikwirakwizwa rya tekinoroji ya XGS-PON na GPON, ikanahuza uburebure bubiri bwumurongo umwe muri module imwe ya optique kugirango hamenyekane uburyo bwogukwirakwiza no kwakira neza ibimenyetso bya optique ya GPON na XGS-PON. PON optique module ifite ibyuma byubatswe bishobora guhuza hejuru no munsi yuburebure bune busabwa kugirango ugabanye XGS-PON na GPON.XGS-PON na XG-PON ukoreshe uburebure bumwe, aribwo burebure bwo hejuru bwa 1270 nm no kumanuka. uburebure bwa 1577 nm.GPON ikoresha uburebure bwa 1310nm hejuru yuburebure bwa 1490nm hamwe nuburebure bwumurongo wa 1490nm, kandi module ya optique ya Combo PON yibice bitatu byerekana fibre imwe yohereza no gutunganya (reba Ishusho 1).
Ibiciro bitatu bya Combo PON itanga ubushobozi bwimikorere ya GPON.Bitewe na tekinoroji ya WDM, umurongo mugari utangwa nicyambu cya PON nigiteranyo cyumuyoboro mugari wa XGS-PON na GPON.Iyo icyambu cya Combo PON cyibiciro bitatu gihujwe icyarimwe na XG (S) -PON terminal na GPON terminal, umurongo wamanuka utangwa na buri cyambu cya PON ni 12.5 Gbps (10 Gbps + 2,5 Gbps), naho umurongo wa uplink ni 11.25 Gbps (10 Gbps + 1.25 Gbps).
ZTE ibisubizo bitatu-Combo PON igisubizo
Ubuyobozi bwa ZTE butatu bwa Combo PON bwakoresheje 8/16-icyambu XGS-PON & GPON ibyuma byububiko byombi.Icyambu kimwe cya Combo PON gihuye na PON MAC ebyiri (GPON MAC na XGS-PON MAC) hamwe n'imiyoboro ibiri ifatika (WDM1r yinjijwe muburyo bwa optique).Mu cyerekezo cyo kumanura, imirongo ibiri yamanutse itunganywa na PON MAC itandukanye, yoherejwe kuri optique module yo kugwiza, hanyuma ikoherezwa kuri ONU zitandukanye.XGS-PON ONU yakira ikimenyetso cya XGS-PON, naho XG-PON ONU yakira XG.. kandi ukeneye gukora gahunda ya DBA kumuyoboro umwe.
Icyambu nimero yikarita ya Combo PON ni ibyambu 8 cyangwa 16.Imigaragarire hamwe nuburyo bugaragara ni umwe-umwe.Ibi byorohereza imiyoborere ya buri munsi no gufata neza ibikoresho hamwe na sisitemu yo gucunga umutungo.Iyo ugena amakuru yo gucunga imiyoboro, ugomba kongeramo ubwoko bushya bwibibaho, hanyuma ukandika GPON, XG-PON, na XGS-PON ONUs kugirango uhite umenya Ubwoko bwa ONU no guhuza umuyoboro. Kuva icyambu cyihuta cya Combo PON cyihuta gihuye numuyoboro ibiri wumubiri, uburyo bwo gufata neza uburyo bukurikira: Icyambu cya Combo PON kirimo imiyoboro ibiri ifatika: GPON na XGS-PON.Imibare yimikorere nogucunga impuruza bigomba kwagurwa hashingiwe MIB yambere (Amakuru yamakuru yo gucunga).
Mubisanzwe kubona amakuru yigenga kumiyoboro ya GPON na XG (S) -PON, birakenewe kubona amakuru yimiyoboro ibiri ifatika icyarimwe.
MIBs zijyanye nibindi bikoresho bya serivisi, imikorere nogucunga neza ntigihinduka.Bashyizwe ku cyambu cya Combo PON, kandi Combo PON ihita ihuza umuyoboro.
Kuyobora inzira yo kubaka 10G PON
Umuvuduko wihuta wa Combo PON urashobora kubona XGS-PON, XG-PON na GPON ubwoko butatu bwa ONU kubisabwa, bushobora guhuza byimazeyo ibyifuzo byabakoresha batandukanye: XGS-PON irashobora gukoreshwa kubakoresha leta hamwe nabikorera ku giti cyabo, na XG -PON irashobora gukoreshwa kubakoresha Home Gigabit, GPON ikoreshwa muburyo busanzwe bwa 100M.
Ugereranije na gahunda yo hanze ya multiplexer, ibyiza bya bitatu-Combo PON biragaragara:
Nta mpamvu yo guhindura ODN, umushinga uroroshye.Iyo multiplexer yo hanze ikoreshwa, birakenewe kongera ibikoresho bya multiplexer, kandi birakenewe guhindura umuyoboro wa ODN murwego runini, bigoye kubishyira mubikorwa mubuhanga, nimwe mumpamvu nyamukuru zituma XG-PON ari bigoye gupima.
Igihombo gishya cyo kwinjiza ntabwo cyatangijwe, kandi ikibazo cya optique power margin cyakemutse rwose.Gukoresha multiplexer yo hanze bizongeramo igihombo cyongeweho 1 ~ 1.5db, nta gushidikanya ko ari bibi cyane kuri bije yingufu nyinshi za optique zimaze gukomera, kandi umushinga ntushobora gushyirwa mubikorwa. Ibiciro bitatu bya Combo PON ntabwo byongera igihombo cyongeweho .Iyo urwego rumwe rwa optique rwemejwe, Combo PON iratangizwa, kandi ingengo yimari yingengo yimari ya optique ya ODN ntabwo ihinduka.
Bika umwanya mucyumba cyimashini kandi woroshye imikorere no kuyitaho. Module yihuta ya Combo PON yihuta ihuza imikorere nka XG (S) -PON, GPON, na WDM1r.Ntabwo yongeyeho ibikoresho byinyongera kandi ntabwo ifata umwanya wicyumba cyinyongera, koroshya kubungabunga no kuyobora.
OSS iroroshye gukora dock, inzira yo gufungura ntigihinduka, kandi umurongo wo hejuru uciwe.Ibice bitatu byihuta Combo PON ifata uburyo bwa WDM.Umuyoboro wa XG (S) -PON hamwe numuyoboro wa GPON uhita uhuzwa nubwoko bwabo bwanyuma.Ibiriho XG (S) -PON na GPON byahujwe na OSS, kandi inzira yo gufungura serivisi ntigihinduka.Biroroshye gufungura, umushinga uroroshye guca.
Igisubizo cyibiciro bitatu bya Combo PON cyakiriwe neza nabakoresha ibikorwa rusange nka Orange, Telefonica na China Mobile.Bishingiye ku gisubizo cya Combo PON hamwe n’ubucuruzi bunini, ZTE yitabiriye cyane ikizamini cya Combo PON y’ibiciro bitatu kandi imyitozo yubucuruzi yabakora ibikorwa rusange, kandi ikomeza kuyobora inzira ya 10G GPON.
