Namuhla, emadolobheni omphakathi, amakhamera okuqapha afakwa ngokuyisisekelo kuwo wonke amagumbi.Sizobona amakhamera okuqapha ahlukahlukene ezakhiweni eziningi zokuhlala, ezakhiweni zamahhovisi, ezinxanxatheleni zezitolo, emahhotela nakwezinye izindawo ukuze sinqande ukwenzeka kwemisebenzi engekho emthethweni.
Ngokuthuthuka okuqhubekayo komnotho nobuchwepheshe, ukuqwashisa kwabantu ngokugadwa kokuphepha kuyanda njalo, futhi nokuqapha kwezokuphepha kuyadingeka kunoma iyiphi indawo.Kodwa-ke, inkimbinkimbi yokuthuthukiswa kwedolobha kwenza uhlelo lokuqapha lwezindlela zokufinyelela zendabuko lungakwazi ukuhlangabezana ngokugcwele nezidingo, futhi i-PON iyamukelwa.Uhlelo lokuqapha ukufinyelela kwenethiwekhi kancane kancane seludumile.
Njengethuluzi lokufinyelela elibalulekile ohlelweni lwe-PON, ukukhetha kwe-ONU kubalulekile, ngakho-ke iyiphi i-ONU engcono nokuthi ungayikhetha kanjani?
I-ONU iyisisetshenziswa sokugcina somsebenzisi sezinhlelo zokusebenza ze-PON kanye nomkhawulokudonsa ophezulu kanye nesisetshenziswa esibulalayo esingabizi kakhulu esidingekayo ukuze kushintshwe isuka “enkathini yekhebula yethusi” iye “enkathini yefiber optical”.Idlala indima ebalulekile ekwakhiweni kwenethiwekhi.
I-ONU iyunithi yenethiwekhi yokubona, esebenzisa umcu weyunithi ukuze ixhume ehhovisi elimaphakathi le-OLT ukuze inikeze izinsizakalo ezifana nedatha, izwi, nevidiyo.Inesibopho sokwamukela idatha ethunyelwe yi-OLT, iphendula imiyalo ethunyelwe yi-OLT, igcine 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.Eyokugcina inomsebenzi we-PoE, okungukuthi, inezindawo ezimbalwa ze-PoE.Ungaxhuma amakhamera okuqapha ngalezi zindawo zokusebenzelana.Asebenza ngokujwayelekile futhi asuse izintambo zokuphakela amandla eziyinkimbinkimbi.
Ngokungeziwe kumachweba we-PoE, ama-ONU ane-PoE kufanele abe ne-PON.Ngale PON, bangaxhunywa ku-OLT ukuze bakhe inethiwekhi ye-PON iyonke.
