Pamene anONUimatulutsa kuwala popanda kuyika sitampu ya nthawi, idzasemphana ndi zizindikiro za onus zina, zomwe zidzakhudza kulankhulana kwabwino kwa ma onus ena kapena onse. Chizindikiro cha nthawiyo chikuwonetsa kuti ali ndi vutoONUsichitumiza zizindikiro zowonekera pamwamba.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.

WopusaONUntchito kuzindikira zikuphatikizapo njira ziwiri:
1. OLTkuzindikira
Pamene aOLTamazindikira kutulutsa kwa nthawi yayitaliONU, imatumiza malangizo odzipatula ONU malinga ndi ONU yomwe yapezeka. Nthawi zambiri, aOLTKuzindikira kumagwiritsidwa ntchito kwa nthawi yayitaliONU, ndipo pali cholakwika china pakuzindikiritsa zotulutsa mwachisawawaONU.Mwachikhazikitso, aOLTkuzimitsaOLTkuzindikira ntchito. Panthawi imeneyi, aOLTamatha 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.TheOLTakhoza kuzindikira zenizeniONUyomwe imatulutsa kuwala pansi pa doko la PON ndipo imatha kuwongolera kutali kuti muzimitsa mphamvu yotumiziraONUOptical module; Chofunikira ndichakuti ma ONU onse omwe ali pansi pa mawonekedwe a PON amafunikira kuti athe kufotokozera uthenga wa downlink ploam ndikuyankha molondola.
2. ONUpang'ono
Pamene aONUikazindikira kutulutsa kwautali wautali, imangodzipatula. Izi ntchito azindikire ndiONUndi 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 zikhalidwe ziwiri akapeza zovuta. Chimodzi ndi chakuti ntchito yowunikira 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 ochita zoipa kwa nthawi yaitaliONU, kuwalola kuti apezeONUmalo ophatikizidwa 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 ndi kufotokozera kwachidziwitso cha "momwe wonyengaONUzidakhalapo” zobweretsedwa kwa inu ndi Shenzhen HDV photoelectric Technology Co., Ltd.
