| Ibanga Lokudlulisa | Igcina amandla esignali ngaphezu kwamakhilomitha | Isebenza kahle kumabanga amafushane kuya kwaphakathi |
| Izindleko Nokufakwa | Izindleko zokuqala ziphakeme kodwa azinaso isiqinisekiso sesikhathi esizayo | Kungabizi kakhulu futhi kulula ukukusebenzisa |
Ikhebula le-coaxial lisebenzisa izimpawu zethusi kanye nezikagesi, kuyilapho i-fiber optic isebenzisa ukukhanya. Ama-fiber optic anikeza isivinini esisheshayo esilinganayo, ukubambezeleka okuphansi, kanye nokukhula okungcono, okwenza kube kuhle kakhulu ezinhlelweni zokusebenza ezidinga idatha eningi. Kodwa-ke, amakhebula e-coaxial ahlala eyindlela ewusizo nengabizi kakhulu ye-broadband kanye ne-inthanethi yebhizinisi, ikakhulukazi lapho kudingeka khona i-bandwidth ephezulu kanye nokuphazamiseka okuncane ebangeni elifushane kuya kweliphakathi.
Izintambo ze-coaxial nazo zinikeza izinzuzo eziningana ngaphezu kwezinketho ezijwayelekile ze-coaxial:
• Ihlala isikhathi eside futhi imelana nomonakalo.
• Ukumelana okuhle kokuphazamiseka kwe-electromagnetic.
• Ishibhile futhi kulula ukuyihlela noma ukuyikhulisa.
• Kulula ukuxhuma ucingo nokufaka.
Ukulahleka kwesignali kuyanda ngobude bekhebula, ngakho-ke ukusebenzisa izintambo ze-coaxial ezimfushane nezijiyile kusiza ukunciphisa ukuncishiswa kwejubane nokugcina ukusebenza kahle.
Izinhlelo Zokusebenza Ze-5G Zangempela
Izintambo ze-coaxial ezilahlekelwa kancane zisetshenziswa kabanzi engqalasizinda engu-5g, kufaka phakathi iziteshi zesisekelo, ama-antenna, kanye namanethiwekhi asatshalaliswayo. Lezi zintambo zisekela ukuthunyelwa kwengqalasizinda ebalulekile ngokuqinisekisa ukuxhumana okuthembekile kwe-broadband kanye nokudluliswa kwedatha okusheshayo. Eziteshini zesisekelo ze-5G, izintambo ze-Telsto feeder zixhuma ama-antenna kumayunithi omsakazo, zigcina ubuqotho besiginali futhi zinciphisa isidingo sama-repeater.
Imikhuba evamile yokufaka izintambo ze-coaxial ezilahlekelwa kancane ihlanganisa:
• Ukuhlola okuphelele kwesayithi ukuze kugwenywe izinguquko zesikhathi esizayo.
• Ukusebenzisa imishini eqinisekisiwe ukuvimbela izinkinga zomthetho.
• Ukulebula ngokucacile amakhebula nama-port ukuze kube lula ukuxazulula izinkinga.
• Ukugcina imibhalo eningiliziwe yokubekwa kwe-antenna kanye nemiphumela yokuhlolwa kokuhambisana.
Ezindaweni zokugcina impahla, ama-antenna afakwa kuma-I-beams noma kuma-bracket enziwe ngokwezifiso aphezulu ophahleni ukuze kugwenywe ukuphazamiseka okuvela kuma-racking. Ezindaweni zehhovisi, ama-antenna afakwa ophahleni oluwela phansi noma ezindongeni, kanti izintambo zidluliselwa ezindleleni ezilinganiselwe umlilo ukuze kuphephe.
Naphezu kwezinzuzo zazo eziningi, ukufaka izintambo ze-coaxial ezilahlekelwa kancane engqalasizinda engu-5g kungaletha izinselele. I-Passive Intermodulation (PIM) ingabangela ukuphazamiseka, kuthinte ukuthembeka kanye namazinga edatha. Ukufakwa kungaba nzima ngenxa yenethiwekhi ebanzi yamaseli amancane kanye nesidingo sokushintshashintsha okunembile kanye nokuvalwa kwesimo sezulu. Izinqubo ezidinga umsebenzi omningi zingaholela ezinseleleni zezokuthutha kanye namaphutha okufakwa angaba khona. Kodwa-ke, ngokuhlela okufanele kanye nemikhiqizo esezingeni eliphezulu njengezintambo ze-Telsto feeder, lezi zinselele zingaphathwa ngempumelelo.
Qaphela: Ukukhetha uhlobo olufanele lwekhebula le-coaxial kukhulisa ukuzuza kwesignali futhi kuthuthukisa ukusebenza, ikakhulukazi kumasignali avame kakhulu asengozini yokulahlekelwa.
Izintambo ze-coaxial zihlala ziwumgogodla wokuxhumana okuhlakaniphile kwingqalasizinda ye-5g. Amandla azo okuletha ukuxhumana okuqhubekayo, ukumelana nokuphazamiseka kwangaphandle, kanye nokusekela izinhlelo zokusebenza ze-bandwidth ephezulu kuzenza zibe yinto ebalulekile kwingqalasizinda ebalulekile yesimanje.
Izintambo ze-coaxial ezilahlekelwa kancane, njengekhebula le-Telsto Feeder, zibalulekile engqalasizinda ye-5G. Onjiniyela batusa lezi zintambo ngoba:
• Phatha amasignali asebenzisa imvamisa ephezulu kahle
• Nikeza isivikelo esiqinile ekuphazamisekeni
• Hlanganisa kalula kumamojula amancane
• Kuletha ukuqina ezindaweni ezivame ukudlidliza
Khetha izintambo zekhwalithi ukuqinisekisa amanethiwekhi athembekile futhi asebenza kahle.
