Namuhla, emadolobheni omphakathi, amakhamera okuqapha afakwa ngokuyisisekelo kuwo wonke amagumbi.Sibona amakhamera ahlukahlukene okuqapha ezakhiweni eziningi zokuhlala, ezakhiweni zamahhovisi, ezinxanxatheleni zezitolo, emahhotela nakwezinye izindawo ukuze kuvinjelwe ukwenzeka kwemisebenzi engekho emthethweni.
Ngokuthuthuka okuqhubekayo komnotho nobuchwepheshe, ukuqwashisa kwabantu ngokuqapha kwezokuphepha kuhlala kuthuthuka, futhi kuyadingeka ukuthi noma iyiphi indawo kufanele ibe nokugadwa kwezokuphepha.Kodwa-ke, inkimbinkimbi yentuthuko yasemadolobheni yenza uhlelo lokuqapha lwemodi yokufinyelela evamile lungakwazi ukuhlangabezana ngokugcwele nezidingo, futhi uhlelo lokuqapha olusebenzisa ukufinyelela kwenethiwekhi ye-PON luya ngokuya luthandwa.
Njengedivayisi yokufinyelela ebalulekile ohlelweni lwe-PON, ukukhetha kwe-ONU kubalulekile.Ngakho-ke iyiphi i-ONU engcono nokuthi ungayikhetha kanjani?
I-ONU iyisisetshenziswa sokuphela komsebenzisi sezinhlelo zokusebenza ze-PON.Kuwumkhawulokudonsa ophezulu futhi idivayisi yokugcina engabizi kakhulu edingekayo ekushintsheni ukusuka "enkathini yekhebula yethusi" kuya "kwinkathi ye-fiber optical".Idlala indima ebalulekile ekwakhiweni kwenethiwekhi.
I-ONU iyunithi yenethiwekhi yokubona, esebenzisa i-fiber eyodwa ukuze ixhume ehhovisi eliphakathi le-OLT ukuze inikeze izinsizakalo ezifana nedatha, izwi, nevidiyo.Inesibopho sokwamukela idatha ethunyelwe i-OLT, iphendula imiyalo ethunyelwe yi-OLT, igcina idatha futhi iyithumele ku-OLT.Idinga ukuzwela okuphezulu futhi kulula ukuyisebenzisa.
Ama-ONU ahlukaniswe ama-ONU ajwayelekile kanye nama-ONU ane-PoE.Eyangaphambili iyidivayisi ye-ONU evame kakhulu futhi i-ONU esetshenziswa kakhulu.Eyakamuva i-PoE-iyakwazi, okungukuthi, inamachweba we-PoE amaningana, lapho amakhamera okuqapha angaxhunywa ukuze awenze asebenze ngendlela evamile futhi asuse izintambo zamandla eziyinkimbinkimbi.
Ngaphezu kwembobo ye-PoE, i-ONU ene-PoE kufanele ibe ne-PON.Ngale PON, ingaxhunywa ku-OLT ukuze yakhe inethiwekhi ye-PON iyonke.
Njengamanje, lolu hlobo lwe-ONU ene-PoE luthandwa izinkampani zobunjiniyela eziqaphayo.Isibonelo, intengo ye-ONU ye-Sushan Weida iphezulu kakhulu, kodwa ixazulula izinkinga eziningi ezingadingekile.Ngakho-ke, uma inethiwekhi ye-PON isetshenziswa kuphrojekthi yokuqapha, i-ONU enomsebenzi we-PoE ingakhethwa.
