Izici Zomkhiqizo

I-LM240TUW5 imodi ekabili ye-ONU/ONT isebenza ku-FTTH/FTTO, ukuze inikeze isevisi yedatha esekelwe kunethiwekhi ye-EPON/GPON.I-LM240TUW5 ingahlanganisa ukusebenza okungenantambo nokuhlangabezana namazinga obuchwepheshe angu-802.11 a/b/g/n/ac, isekela nesignali engenantambo engu-2.4GHz kanye ne-5GHz.Inezici zamandla okungena aqinile kanye nokufakwa okubanzi.Ingahlinzeka abasebenzisi ngokuvikeleka kokudluliswa kwedatha okusebenza kahle kakhulu.Futhi ihlinzeka ngezinsizakalo ze-TV ezingabizi nge-1 CATV Port.

Ngesivinini esingafika ku-1200Mbps, i-4-Port XPON ONT inganikeza abasebenzisi ukuseshwa kwe-inthanethi okushelelayo okungavamile, ukushaya ucingo nge-inthanethi, kanye nokudlala ku-inthanethi.Ngaphezu kwalokho, ngokwamukela i-antenna yangaphandle ye-Omni-directional, i-LM240TUW5 ingakhuphula kakhulu ububanzi obungenantambo nokuzwela, okukwenza ukwazi ukuthola amasignali angenantambo ekhoneni elikude lekhaya noma ihhovisi lakho.Ungakwazi futhi ukuxhuma ku-TV futhi unothise impilo yakho.

I-ONU (Optical Network Unit) iyisisetshenziswa sokudlulisa amehlo esisetshenziswa ohlelweni lokuxhumana lwe-fiber optic enemisebenzi emibili “yokuthumela” kanye “nokwamukela”.Kuyidivayisi ekunethiwekhi yamehlo exhuma izintambo ezibonakalayo kumishini yomsebenzisi.Ukuxhumana kwe-Fiber optic ubuchwepheshe bokuxhumana obusebenzisa ukukhanya njengesignali ye-Bellman, i-ONU ingenye yemishini ebaluleke kakhulu yokuxhumana nesignali nokudlulisa.Uma kuqhathaniswa nemishini evamile yenethiwekhi, i-ONU inezici ezimbili:

Okokuqala, mayelana nokuxhumana ngokomzimba, i-ONU isebenzisa izintambo ze-fiber optic esikhundleni sezintambo zenethiwekhi zendabuko.Ngenxa yokuthi ikhebula le-fiber optic linejubane eliphezulu lokudlulisa, umthamo omkhulu wokudlulisa idatha, nebanga elide lokudlulisela, ifaneleka kakhulu ukudluliswa kwedatha ngesivinini esikhulu kanye nesivinini esikhulu.

Okwesibili, i-ONU isebenzisa ubuchwepheshe obuyingqayizivele be-TDMA (I-Time Division Multiple Access) ukuze idlulisele ngokuthembekile idatha kubasebenzisi abahlukene ngezikhathi ezihlukahlukene ukuze kuqinisekiswe ukuzinza nokuvikeleka kokudluliswa kwedatha.

Izimfuneko

Ukuthuthukiswa kweNhlangano Yezizwe Ezihlangene kwasheshisa kakhulu ukuthuthukiswa kwe-broadband.Ububanzi ngokuvamile bunezici ezintathu ezilandelayo:

1. Thola ububanzi bendlu

Ngaphezu kwalokho, izidingo zedijithali zemindeni yesimanje ziye zanda futhi kunesidingo sokuthumela ulwazi olwengeziwe esizeni sasekhaya, esidinga ukusekelwa okusheshayo nokuphumelelayo.Esikhathini esedlule, ubuchwepheshe be-ADSL babunemikhawulo mayelana nesivinini sokudlulisela, kodwa i-UN isebenzisa i-fiber optics ukufinyelela abasebenzisi bokugcina.Isekela isivinini esiphezulu samakhulukhulu ama-megabits, azohlangabezana nezidingo zokuthumela amanani amakhulu wedatha.

2. Ukufinyelela emaphandleni

Ezindaweni zasemakhaya, ukufinyelela kwe-broadband okuvamile kunzima ukuhlangabezana nezidingo zabasebenzisi ngenxa yengqalasizinda elinganiselwe.I-United Nations isebenzisa ubuchwepheshe be-fiber optic obukwazi ukudlulisa idatha ezindaweni ezikude, inikeze isevisi esheshayo ezindaweni zasemakhaya futhi ibe negalelo elikhulu kwingqalasizinda yeNhlangano Yezizwe Ezihlangene.

3. Ukwakheka kwebhizinisi

Ngokuphathelene nebhizinisi, lapho uthumela idatha ezindaweni ezahlukene, i-ONU isebenzisa izindlela ezihlukene nezihlukene zokufinyelela okuningi, okungathuthukisi kuphela ukusebenza kwenethiwekhi, kodwa futhi kuthuthukisa ukuphepha kokudluliswa kwedatha.inkampani.

esizayo

Njengamanje, ngokuthuthukiswa kwe-5G, i-cloud computing nobunye ubuchwepheshe, amanethiwekhi endabuko awakwazi ukuhlangabezana nesidingo esikhulayo.Ngokuphambene, ubuchwepheshe be-fiber optic bunobuhle bokudluliswa kwesivinini esikhulu, ukuzinza okuhle kanye nomkhawulokudonsa obanzi.Ngakho-ke, i-ONU njengedivaysi enwetshiwe inamandla amakhulu okuthuthukiswa.Ngokuzayo, olunye ucwaningo lungenziwa kulezi zindawo ezilandelayo:

1. Ukuthuthukisa ubuchwepheshe obungcono bokuthuthukisa ihadiwe kanye nesivinini sokulanda

Yenza ucwaningo oluqhubekayo ngobuchwepheshe obuhlobene, ugxile ekuthuthukiseni ukuzinza kwe-hardware, ukwandisa isivinini sokudlulisela ngokunciphisa imishini edla amandla, nokunciphisa kakhulu izindleko zokudlulisa inethiwekhi.

2. Nweba ububanzi bokusebenza futhi uqinise uhlelo lolwazi lomphakathi

Izicelo ze-UN azikhawulelwe ezindlini nasemabhizinisini.Ngokuzayo, izindawo zokufaka izicelo zinganwetshwa, futhi isistimu yolwazi lwezenhlalo ingasetshenziswa ezindaweni ezifana nokwakha idolobha elihlakaniphile nokwakha i-inthanethi Yezinto ukuze kuthuthukiswe uhlelo lolwazi.

3. Qinisa ukuphepha kwenethiwekhi futhi uthuthukise ukuphepha komsebenzisi

Njengoba ubugebengu bamakhompuyutha buyahlukahluka futhi buyinkimbinkimbi, ukuphepha kwenethiwekhi kufanele kuqiniswe ukuze kuqinisekiswe ukuvikelwa okuphelele nokuphelele kokudluliswa kwedatha yomsebenzisi.
