ONU (Optical Network Unit) yog cov khoom siv hluav taws xob tseem ceeb hauv fiber ntau -optic access networks. Nws lub luag haujlwm tseem ceeb yog hloov kho qhov muag teeb liab kis tau los ntawm fiber ntau rau hauv cov teeb liab hluav taws xob, muab kev nkag mus rau network rau ntau yam kawg - cov neeg siv khoom siv. Nws qhov kev siv cov xwm txheej feem ntau yog hloov mus rau qhov kev xav tau dav dav rau "fiber rau hauv tsev / tsev / chaw ua haujlwm" thiab tuaj yeem faib raws li hauv qab no:
Cov Tsev Neeg Nyob Hauv Tsev Scenarios
Qhov no yog qhov feem ntau daim ntawv thov scenario rau ONUs, feem ntau hu ua FTTH (Fiber to the Home). Cov chaw muab kev pabcuam khiav fiber ntau optic cables rau hauv tsev, qhov twg ONU feem ntau yog nruab rau hauv chav nyob, kawm, lossis lub thawv hluav taws xob. Nws txuas rau cov khoom siv hauv tsev xws li khoos phis tawj, TVs ntse, thiab routers los ntawm kev sib txuas nrog (Ethernet ports) lossis, nyob rau hauv rooj plaub ntawm wireless - qhib ONUs (feem ntau hu ua "optical modems"), muab tag nrho - tsev Wi-Fi kev pab them nqi. Qhov no ua tau raws li kev xav tau ntawm tsev neeg rau siab - internet ceev, IPTV, suab hu (hauv xov tooj), thiab lwm yam kev pabcuam.
Enterprise thiab Office Scenarios
Rau cov kev xav tau ntawm lub network me me thiab nruab nrab- cov tuam txhab loj lossis cov tsev ua haujlwm, FTTO (Fiber rau Chaw Ua Haujlwm) lossis FTTB (Fiber rau Lub Tsev) qauv tau txais yuav:
Cov lag luam me tuaj yeem siv tauONUncaj qha nyob rau hauv chaw ua hauj lwm cheeb tsam, nthuav cov chaw nres nkoj los ntawm cov keyboards mus txuas ntau lub chaw ua hauj lwm computers, printers, servers, thiab lwm yam khoom siv. Qhov no ua kom ruaj khov gigabit lossis txawm tias 10-gigabit broadband nkag, ntsib cov kev xav tau ntawm kev hloov ntaub ntawv, rooj sib tham video, huab ua haujlwm hauv chaw ua haujlwm, thiab lwm yam.
Hauv cov tsev ua haujlwm loj, fiber ntau yog thawj zaug txuas nrog ONU hauv pem teb chav tsev siv hluav taws xob, thiab tom qab ntawd muab faib rau cov chaw ua haujlwm ntawm ib cheeb tsam network cable.
Kev Lag Luam Kev Lag Luam Scenarios
Ntau lub khw, khw muag khoom, tsev so, thiab lwm qhov chaw lag luam kuj tseem yog thawj daim ntawv thov xwm txheej rau ONUs:
Cov khw muag khoom yooj yim, tsev noj mov, khw muag khaub ncaws, thiab lwm lub khw muag khoom siv ONUs rau kev siv dav dav rau kev txhawb nqa cov ntsiab lus - ntawm - kev muag khoom, them nyiaj QR code, lub koob yees duab soj ntsuam, thiab cov ntxaij vab tshaus digital.
Cov tsev so xa ONUs nyob rau hauv txhua chav lossis hauv txhua lub tsev los muab cov qhua nrog siab -Wi-Fi thiab IPTV cov kev pabcuam, thaum tseem ua tau raws li lub tsev so kev tswj hwm thiab kev saib xyuas kev ruaj ntseg network.
Internet cafes thiab gaming centers yuav tsum muaj siab -bandwidth ONU li ua ke nrog siab -kev ua tau zoo keyboards kom du, siab - internet ceev thiab gaming online rau ntau lub computer ib txhij.
Tsev Kawm Ntawv Qib Siab thiab Kev Pabcuam Pej Xeem
Hauv cov tsev kawm ntawv thiab cov chaw ua si, ONUs muab kev sib txuas lus rau cov tsev qhia ntawv, tsev so, tsev so, chaw ua haujlwm, chaw kuaj mob, thiab lwm yam, txhawb nqa kev kawm, daim npav hauv tsev kawm ntawv, kev saib xyuas kev nyab xeeb, thiab kev tshawb fawb cov ntaub ntawv xa mus.
Cov chaw pabcuam pej xeem xws li tsev kho mob thiab cov chaw pabcuam tseemfwv siv ONUs rau kev nkag mus tau ruaj khov, ua kom muaj kev ua haujlwm zoo ntawm cov tshuab xws li kev teem sijhawm thiab kev them nyiaj, kev xa cov ntaub ntawv kho mob hluav taws xob, thiab tsoomfwv cov chaw ua haujlwm.
Qee lub zej zog ntse thiab cov chaw ua si ntse kuj tseem siv ONUs los ua lub hauv paus rau IoT rooj vag, txuas cov khoom siv xws li kev tswj xyuas kev nkag mus, cov teeb pom kev ntse, thiab kev soj ntsuam ib puag ncig kom muaj kev tswj xyuas ntse.
Hauv luv luv, txhua qhov chaw uas xav tau fiber ntau - optic broadband nkag thiab qhov yuav tsum tau hloov kho qhov muag teeb liab rau hauv cov teeb liab siv tau hluav taws xob rau qhov kawg - cov neeg siv khoom siv, ONU yog siv. Nws yog cov cuab yeej tseem ceeb hauv mais kawg ntawm fiber ntau -optic networks.
Kuv tuaj yeem pab koj sau cov lus siv rau kev xaivONUcov qauv raws li cov xwm txheej sib txawv, ua kom yooj yim rau kev pom zoo cov qauv tsim khoom raws li cov kev xav tau tshwj xeeb. Yog tias koj xav tau qhov no, thov xa email lossis xa email. Kuv ib txwm muaj rau kev sab laj.
