Isingeniso:
Izintambo eziphakelayo zidlala indima ebaluleke kakhulu ezinhlelweni zesimanje zokuxhumana emhlabeni jikelele. Lawa amakhebuli akhethekile aklanyelwe ukuthuthukisa ukusebenza kahle kanye nokusebenza kahle kokudluliswa kwamasignali, ikakhulukazi eziteshini ezidluliswayo zenethiwekhi yokusakaza. Ingqikithi yokuba nezintambo eziphakelayo ilele emandleni azo okuletha amandla namasignali phakathi kwezingxenye ezihlukene ngaphakathi kwesistimu ngenxa yomthamo wazo omkhulu wokuthwala nokulahlekelwa kwesignali ephansi.
Izinhlobo Nokwakheka Kwezintambo Okuphakelayo:
Ngokuvamile, izintambo eziphakelayo zihlukaniswa ngezinhlobo ezimbili eziyinhloko: i-coaxial ne-fiber optic. Eyokuqala, i-coaxial, isetshenziswa kakhulu phakathi kwezinhlelo zokusebenza zefrikhwensi yomsakazo (RF) ngenxa yokuhlukaniswa kwayo okulungiselelwe nokuphazanyiswa yizibuthe kagesi. Le ntambo iqukethe i-conductor yangaphakathi, i-insulator, i-conductor yangaphandle, nesheath yangaphandle. Ibhalansi enhle kakhulu phakathi kokusebenza nezindleko kuvame ukufinyelelwa ngamakhebula angama-coaxial, okuwenza abe yinketho ethandwayo embonini yezokuxhumana.
Ngakolunye uhlangothi, izintambo ze-fiber optic zisebenza njengenye indlela engcono lapho kudingeka khona ukudluliswa kwesignali yebanga elide. Lezi zintambo zisebenzisa imicu yengilazi ngaphakathi kwegobolondo le-insulated, elivumela ukudluliswa kwedatha ngokushesha okukhulu.
Izicelo ze-Feeder Cables:
Izintambo eziphakelayo zivame ukusetshenziswa emikhakheni eyahlukene, okuhlanganisa ezokusakaza, ezokuxhumana, ezobuchwepheshe bolwazi, ezempi, nokunye. Umsebenzi wabo ekuhambiseni amasiginali ukusuka emthonjeni omaphakathi ukuya emugqeni wokusabalalisa noma amadivayisi amaningi kuyindawo yokuthengisa ebalulekile. Lezi zintambo zithola ukusetshenziswa okubanzi ekusethweni kwamanethiwekhi amaselula, lapho amasignali kufanele adluliswe esuka esiteshini esiyisisekelo aye ohlelweni lwe-antenna.
Izintambo eziphakelayo nazo ziwumgogodla wokusebenza kwamanethiwekhi kamabonakude ekhebula. Banomthwalo wemfanelo wokuthutha amasignali kamabonakude ukusuka emthonjeni oyinhloko wokudlulisa ukuya ku-antenna yomphakathi, ukuqinisekisa ikhwalithi ephezulu yesithombe lapho bezamukela.
Izinzuzo ze-Feeder Cables:
Ngokuphawulekayo, izici ezivelele zezintambo eziphakelayo umthamo wazo omkhulu wokuthwala, ukulahlekelwa kwesignali ephansi, nokumelana nokuphazanyiswa yizibuthe. Zakhiwe ngokuqinile ukuze zisebenze kahle ngaphansi kwezimo eziyinselele. Izingxenye ezibalulekile zezinhlelo eziningi zokusakaza nezokuxhumana, lezi zintambo zisiza ekudluliseni okunembile nokusheshayo kwamasignali ezindaweni ezihlukene.
Isiphetho:
Sengiphetha, izintambo eziphakelayo ziyisisekelo sezokuxhumana zesimanje, izinhlelo zokusakaza, namanethiwekhi angenantambo, aqhuba umhlaba oncike kakhulu ekuxhumaneni okusheshayo, okuphumelelayo, nokuthembekile. Ikhono lazo lokunciphisa ukulahleka kwamasignali, ukumelana kwazo nokuphazamiseka, namandla azo okuthwala lilonke kuwenza abe yingxenye ebalulekile emikhakheni eyahlukene yezomnotho. Njengoba ubuchwepheshe buqhubeka buthuthuka, sinjalo nesidingo sokuthuthukiswa okuhambisanayo kumakhebula okuphakelayo, okugcizelela ukubaluleka kwawo okuyisisekelo emhlabeni wethu oxhumene.
