Dongosolo la PON limagwiritsa ntchito ukadaulo wogawanitsa nthawi munjira ya uplink, ndipo ONU imatumiza ma datagraphs kupita ku uplink direction molingana ndi sitampu yanthawi yomwe OLT idaperekedwa.ONU ikatulutsa kuwala popanda kuyika sitampu ya nthawi, imasemphana ndi ma siginecha a onus ena, zomwe zingakhudze kulumikizana kwanthawi zonse kwa ma onus ena kapena onse.Sitampu yanthawi ikuwonetsa kuti ONU yoyipa siyitumiza ma siginecha m'mwamba.The onus wankhanza agawidwa mitundu iwiri, imodzi ndi yowunikira mwachisawawa ndipo ina ndi yowunikira kwautali.Kuonetsetsa kuti machitidwe a PON akugwira ntchito bwino ndikupewa chisokonezo m'dongosolo chifukwa cha kutuluka kwa onus wonyansa mu dongosolo.Huawei ali ndi ntchito yopeza ma ONU achinyengo.Ichi ndi ntchito mu PON system yomwe imayang'ana zotengera zomwe sizitumiza kuwala panthawi yoyenera ndikuzipatula.
Ntchito yodziwika bwino ya ONU imaphatikizapo njira ziwiri:
1. Kuzindikira kwa OLT
Pamene aOLTimazindikira ONU yotulutsa nthawi yayitali, imatumiza malangizo kuti adzipatula ONU malinga ndi ONU yomwe yapezeka.Nthawi zambiri, ntchito yowunikira OLT imagwiritsidwa ntchito ku ONU yomwe imatulutsa nthawi yayitali, ndipo pali cholakwika china pakuzindikiritsa ONU yotulutsa mwachisawawa.Mwachikhazikitso, OLT imazimitsa ntchito yozindikira OLT.Panthawiyi, OLT imatha kuzindikira ngati pali onus yotulutsa nthawi yayitali pamzere wa PON.Komabe, imatha kuweruza ngati pali onus yotulutsa nthawi yayitali pansi pa doko la PON, ndipo silingapeze mwayi wina.Iyenera kupeza onus wankhanza kudzera pa fiber disconnection pamalopo.TheOLTimatha kuzindikira ONU yeniyeni yomwe imatulutsa kuwala pansi pa doko la PON ndipo imatha kulamulira kutali kuti izimitse mphamvu yotumizira ya ONU optical module;Chofunikira ndichakuti ma ONU onse omwe ali pansi pa mawonekedwe a PON amafunikira kuti athe kufotokozera uthenga wa downlink ploam ndikuyankha molondola.
2. ONU pang'ono
Pamene aONUikazindikira kutulutsa kwautali wautali, imangodzipatula.Ntchitoyi imatha kuzindikira ONU ndi kutulutsa kwautali wautali komanso kutulutsa kwachisawawa.
3. Zolepheretsa kasamalidwe ka netiweki pakuzindikira onus achinyengo
Malinga ndi mfundo zomwe zili pamwambazi, kasamalidwe ka ma netiweki amayenera kukumana ndi mikhalidwe iwiri pozindikira zovuta.Chimodzi ndi chakuti ntchito yozindikira yatsegulidwa, ndipo ina ndikuti onse onus pansi pa doko la PON akhoza kusanthula uthenga wa downlink ploam ndikuyankha molondola.
Chifukwa chake, kasamalidwe ka netiweki ali ndi mwayi wina wopeza komanso kuzindikira zidziwitso za chipangizochoONUkwa ONU yankhanza yotulutsa nthawi yayitali, kuwalola kupeza malo a ONU kuphatikiza ndi kasamalidwe ka katundu;Kwa onus yachinyengo yomwe imatulutsa kuwala pang'onopang'ono, palibe njira yabwino yopezera ndi kupeza.
Njira yayikulu yopangira ma onus achinyengo akadali kuyesa kokakoka pang'onopang'ono pa optical splitter, kotero ndikofunikira kwambiri kusinthira chidziwitso pakuwongolera katundu.
Zomwe zili pamwambazi ndizofotokozera chidziwitso cha "momwe ONU wonyenga adakhalira" adabweretsedwa kwa inu ndi Shenzhen HDV photoelectric Technology Co., Ltd. Zolankhulana zopangidwa ndi kampani zimaphimba;
Magawo a module: Optical fiber modules, Ethernet modules, Optical fiber transceiver modules, optical fiber access modules, SSFP Optical modules,ndiSFP kuwala ulusi, ndi zina.Gulu la ONU: EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON PA, ndi zina.
kalasi ya OLT: Kusintha kwa mtengo wa OLT, Mtengo wa GPON OLT, EPON OLT, kulankhulana OLT, etc.
Zomwe zili pamwambazi zitha kuthandizira pazochitika zosiyanasiyana zapaintaneti.Gulu la akatswiri komanso lamphamvu la R&D litha kuthandiza makasitomala omwe ali ndi zovuta zaukadaulo, ndipo gulu loganiza bwino komanso laukadaulo litha kuthandiza makasitomala kupeza ntchito zapamwamba panthawi yokambirana zisanachitike komanso pambuyo popanga.Takulandirani kuLumikizanani nafepafunso lamtundu uliwonse.
