MuChina, 100M optical Broadband yave yakakurumbira, uye nguva yeGigabit yave kuda kuvhurwa.Muna 2019, Ministry of Industry and Information Technology yakatanga "Double G Double Lifting, Same Network Same Speed" chiito chebroadband network, uye yakaramba ichikurumidza kusimudzirwa kwezvakagadziriswa mashandisirwo emagetsi eGigabit.10G GPON teknolojia inogona kubudirira kubva ku "zana." megabytes" kusvika "gigabit".10G GPON tekinoroji inoreva matekinoroji akadai seXG-PON, XG-PON & GPON Combo, XGS-PON, XGS-PON & GPON Combo.Iko kushanduka kune 10G GPON inoda kutarisa nyaya dzekuenderana dzeONU dzakasiyana.
Kuti tigadzirise dambudziko rekuti XG-PON haienderane neGPON ONU, ZTE ndiyo yekutanga kutaura tekinoroji yeCombo PON kuona XG-PON & GPON Combo. inogamuchirwa nevashandisi nekuda kwekuenderana kwayo kwakanaka uye nyore.Yakava mhinduro huru yekuvaka 10G GPON uye inowanikwa mune zvekutengeserana pamwero mukuru.
Ikozvino XGS-PON tekinoroji yave yakakura, uye XGS-PON inogona kupa 10G yekumusoro uye yakadzika symmetric bandwidth, asi XGS-PON OLT inogona chete kuenderana neXGS-PON uye XG-PON marudzi maviri eONU, nepo nhamba huru yeGPON. uye ONU inoiswa mumambure aripo, uye kuenderana kweiyo iripo network GPON uye ONU inofanirwa kugadziriswa kana network ichishanduka kuenda kuXGS-PON. uye GPON yekushandisa Combo, inotsigira kukwidziridzwa kwakanaka kweGPON kuenda kuXGS-PON.
Matatu-chiyero Combo PON tekinoroji musimboti
XGS-PON&GPON's Combo PON mhinduro ndeye yakavakirwa-mukati multiplexer mhinduro inotsigira XGS-PON/XG-PON/GPON matatu-modhi kugarisana. yakanakisa mhinduro yekusimudzira yakatsetseka yeGPON kuenda kuXGS-PON.
Iyo mitatu-chiyero Combo PON inoshandisa musimboti weakasiyana mutakuri wavelengths neXGS-PON uye GPON matekinoroji, uye inosanganisa maviri wavelengths mune imwe optical module kuona yakazvimirira kutapurirana uye kugashira kugadzirisa kweGPON uye XGS-PON masaini masaini.Iyo matatu-kumhanya Combo PON optical module ine yakavakirwa-mukati musanganisi inogona kusanganisa kumusoro nekudzika wavelengths ina inodiwa kupatsanura XGS-PON uye GPON.XGS-PON uye XG-PON inoshandisa wavelength yakafanana, inova yavelength yekumusoro ye1270 nm uye yakadzika. wavelength ye1577 nm.GPON inoshandisa 1310nm kumusoro kwewavelength uye 1490nm kudzika kwewavelength, uye matatu-chiyero Combo PON optical module inoona imwe-fiber mana-wavelength kutapurirana uye kugadzirisa (ona Mufananidzo 1).
Iwo matatu-chiyero Combo PON inopa kugona kweanoenderana GPON zviteshi.Nekuda kweiyo WDM tekinoroji, bandwidth yakapihwa nePON port ndiyo chiyero cheiyo bandwidth yeXGS-PON uye GPON chiteshi. Kana matatu-chiyero Combo PON port yakabatana kune XG (S) -PON terminal uye GPON terminal, iyo downlink bandwidth inopiwa nePON imwe neimwe chiteshi i12.5 Gbps (10 Gbps + 2.5 Gbps), uye iyo uplink bandwidth i11.25 Gbps (10 Gbps + 1.25 Gbps).
ZTE's matatu-chiyero Combo PON mhinduro
ZTE's matatu-reti Combo PON board inotora 8/16-chiteshi XGS-PON&GPON mbiri-chiteshi hardware dhizaini.Imwe Combo PON port inoenderana nePON MAC mbiri (GPON MAC uye XGS-PON MAC) uye miviri miviri yemuviri (WDM1r inosanganiswa mune optical module).Munzira yedownlink, mafungu maviri ekudzikisa anogadziriswa nePON MAC yakasiyana, inotumirwa kune optical module ye multiplexing, uye yozotumirwa kune dzakasiyana ONU.Iyo XGS-PON ONU inogamuchira chiratidzo cheXGS-PON, uye XG-PON ONU inogamuchira XG.– PON chiratidzo, GPON ONU inogamuchira GPON chiratidzo.Mukukwira kumusoro, GPON neXGS-PON vanoshandisa mawavelengths akasiyana, sefa kutanga mune optical module, uye vozogadzira mumatanho eMAC akasiyana.XGS-PON neXG-PON vanoshandisa wavelength yakafanana. uye inoda kuita DBA kuronga pane imwechete chiteshi.
Nhamba yechiteshi cheCombo PON kadhi ndeye 8 kana 16 ports.Chitarisiko uye chimiro chemuviri chiri chimwe-kune-chimwe.Izvi zvinogonesa manejimendi ezuva nezuva uye kuchengetedzwa kwechishandiso uye resource manejimendi system.Paunenge uchigadzira network manejimendi data, iwe unofanirwa kuwedzera rudzi rutsva rwebhodhi, uye nhamba yeGPON, XG-PON, uye XGS-PON ONUs kuti uzvizivise otomatiki. ONU mhando uye gadzirisa chiteshi.Sezvo matatu-speed Combo PON port inoenderana nematanho maviri emuviri, maitiro ekuchengetedza ekuchengetedza akadai seanotevera: A Combo PON port inosanganisira miviri miviri yemuviri: GPON uye XGS-PON.Nhamba dzekuita uye alarm manejimendi inoda kuwedzerwa zvichibva pane yekutanga MIB (Management Information Base).
Pakutanga kuwana ruzivo rwakazvimiririra kune GPON uye XG (S) -PON chiteshi, zvinodikanwa kuwana ruzivo rwematanho maviri emuviri panguva imwe chete.
Iwo maMIB ane hukama kune mamwe masevhisi magadzirirwo uye mashandiro uye manejimendi manejimendi anoramba asina kuchinjika.Iwo akagadziridzwa kuCombo PON port, uye iyo Combo PON inozvigadzirisa kune chiteshi.
Inotungamira maitiro e10G PON kuvaka
Iyo mitatu-kumhanya Combo PON inokwanisa kuwana XGS-PON, XG-PON uye GPON matatu marudzi eONU painodiwa, ayo anogona kuzadzisa zvinodiwa nevashandisi vakasiyana: XGS-PON inogona kushandiswa kuhurumende uye bhizinesi vashandisi vemitsara yakazvimirira, uye XG. -PON inogona kushandiswa kune Kumba kweGigabit vashandisi kuwana, GPON inoshandiswa kune yakajairwa 100M munyoreri kuwana.
Kuenzaniswa neyekunze multiplexer scheme, zvakanakira iyo matatu-chiyero Combo PON zviri pachena:
Hapana chikonzero chekugadzirisa ODN, purojekiti iri nyore.Kana yekunze multiplexer ichishandiswa, zvinodikanwa kuwedzera iyo multiplexer mudziyo, uye inofanirwa kugadzirisa iyo ODN network pamwero wakakura, izvo zvakaoma kuita muinjiniya, ndicho chimwe chezvikonzero nei XG-PON iri. zvakaoma kuyera.
Iyo nyowani yekuisa kurasikirwa haina kuunzwa, uye dambudziko re optical simba margin rinogadziriswa zvachose.Kushandiswa kwekunze multiplexer kuchawedzera imwezve 1 ~ 1.5db yekuisa kurasikirwa, iyo isina mubvunzo yakaipisisa kune akawanda optical magetsi mabhajeti ayo atove akaoma, uye purojekiti haigoni kushandiswa.Iyo mitatu-chiyero Combo PON haiwedzeri kuwedzera kurasikirwa kwekuisa. .Kana iyo yakafanana optical module level inogamuchirwa, iyo Combo PON inounzwa, uye iyo optical simba bhajeti margin yeODN network haichinji.
Chengetedza nzvimbo muimba yemuchina uye kurerutsa kushanda nekugadzirisa.Iyo mitatu-speed Combo PON optical module inobatanidza mabasa akadai seXG (S) -PON, GPON, uye WDM1r.Iyo haiwedzere mimwe michina uye haitore imwe nzvimbo yekamuri, kurerutsa kugadzirisa uye manejimendi.
OSS iri nyore kuisa, nzira yekuvhura haina kuchinjwa, uye mutsara wepamusoro wakachekwa.Iyo mitatu-speed Combo PON inotora WDM mode.Iyo XG(S)-PON chiteshi uye GPON chiteshi zvinongoenderana nemhando dzadzo dzekupedzisira.Iyo iripo XG (S) -PON neGPON yakabatana neOSS, uye nzira yekuvhura sevhisi inoramba isingachinji.Zviri nyore kuvhura, chirongwa chiri nyore kucheka.
Iyo yetatu-chiyero Combo PON mhinduro yakagamuchira kutariswa kwakawanda kubva kune vanonyanya mashandiro akadai seOrange, Telefonica neChina Mobile.Kubva paCombo PON mhinduro uye hukuru hwekutengesa maitiro, ZTE yakatora chikamu muyero-yechitatu Combo PON bvunzo uye tsika yekutengeserana yevashandi vemazuva ose, uye yakaramba ichitungamirira 10G GPON yekuvaka maitiro.
